fumed, that Dr. Solano, tho' he never gave any explanation. "of this matter, understood in the preceding article that mea"fure of interval which the regular pulfations, between the "intermiffions, bear the one to the other in every Patient.

3. "A tenfion of the artery joined to the Intermitting Pulfe, is a certain sign of a critical Vomiting fuperadded to the "Diarrhoea.

4. "A greater or lefs tenfion of the artery, denotes a greater or less evacuation by Vomiting, more or fewer efforts to vo"mit. The length of the intermiffion fimply relates to the quantity of the conjoint Diarrhoea, or the number of ftools.

5. "The Doctor has never obferved a fimple crifis by Vo"miting without a Diarrhea, or, confequently, whether fuch "a crifis has any particular fign, unknown to the antients.

6. "A foftness of the artery joined with the intermiffion, "is a certain fign of a crifis by Urine with the Diarrhoea; and "the greater or lefs quantity of excretion of Urine is denoted, by the greater or le's degree of foftness in the artery.

7. "Dr. Solano has not observed a fimple crifis by Urine, without the complication of a Diarrhoea in fome degree, and was not acquainted with any fign of fuch a crifis."

To the above Dr. Cox has thought it neceffary to add, from the fame Author, the following rules, which, tho' applied in the original, only to the Pulfus Dicrotus, or rebounding Pulse, are remarked to be common to all the critical Pulfes*.

Rule 2. Concerning the rebounding Pulfe.-" When the re"bounding Pulfe appears at or about every thirtieth Pulfation, "the Hæmorrhage commonly follows in four days after, fome"what fooner, or fomewhat later. When it recurs at every "fixteenth Pulfation, the Hæmorrhage fupervenes in three "days. When it is obferved at every eighth Pulfation, the "Hæmorrhage is to enfue in two days, or in two days and a half. "Laftly, When it recurs at every fourth, third, or second "Pulfation, or is continual, the Hæmorrhage is to be expected "in twenty-four hours.-Therefore, in general, the shorter "the periods of Pulfation, at which the rebounding recurs, the "nearer the Hæmorrhage.

* If, adds our Author, the word intermitting is substituted for rebounding, and Dia rhea for Hamorrhage, Solano's meaning will ⚫ be obvious.'

3.

"Sometimes Nature runs regularly through all the fore" mentioned progreffions of the critical Pulfe, from its first appearance, at every thirtieth, down to every fingle Pulfation, by which the Hæmorrhage is forefeen gradually approaching in the fame degree. She fometimes inordinately haftens or delays the Hemorrhage; and then the rebounding of the "Pulle recurs with more or lefs frequency in the fame propor❝tion. And when this returns in variable fhifting periods, the time at which the Hæmorrhage is to happen, cannot be "exactly determined.

"

6. According as the blood flows, the rebounding of the artery gradually flackens, untill it entirely difappears foon "after the crifis; and gradual remiffion of the rebounding, is the fign of an immediately preceding Hæmorrhage.

7. "If after the Hæmorrhage the rebounding of the Pulfe "fhould continue, or appear again, it denotes another crifis of the fame kind, according to the above-mentioned rules.”—

In difcharge of the fecond part of his engagement, our Author gives twelve cafes from Dr. Nihel; and, in the third part, feven which fell under his own obfervation, with one communicated to him by Dr. Layard of Huntingdon. Thefe_cafes appear to be related with candour and integrity; and Dr. Cox's obfervations on them, feem pertinent and judicious. The prognoftic was generally verified by the event; and though they may not be deemed fufficient abfolutely to afcertain the doctrine intended to be hereby fupported, they certainly merit the serious attention of every well-difpofed Practitioner in phyfic.

In the opening of his fourth chapter, the Doctor reminds his Readers, that his obfervations are confined to only one of Solano's three critical Pulfes, viz. the Intermitting Pulfe, as it appears to have been a SIGN of a Diarrhea. The practical remarks deduced are 1. That the Intermitting Pulfe, in acute difeafes, the Diarrhoea not being prefent, indicates the ufe of purging remedies.-2. That when the Diarrhoea is prefent, and is accompanied by the Intermitting Pulse, the appearance of this fymptom prohibits the administration of aftingent remedies.-3. If this fymptom, the Intermitting Pulse, has been ufually found to ceafe on the access or conti• nuance of a natural Diarrhoea, or one procured by art; and if, with its difappearance, a train of other threatning fymptoms have likewife ceafed, and the Patient has recovered of the general distemper, by means of this Diarrhoea; that then it may, from analogy, be inferred, that a difeafe, attended with the fame fymptoms, arifing from the fame cause, though

• not

not accompanied by the Intermitting Pulfe, may be expected to yield to the fame method of cure.'

What has been faid, may ferve to convey an idea of this useful performance.-Our Author has fo modeftly apologized for what may, by fome, be thought defects, that to mention them would look more like ill-nature, than candid criticism.

A new Naval History, or compleat View of the British Marine. In which the Royal Navy, and the Merchants Service, are traced through all their Periods and different Branches: With the Lives of the Admirals and Navigators who have honoured. this Nation, and distinguished themselves by their Conduct, Courage, Victories, and Difcoveries. Including the most confiderable Naval Expeditions and Sea Fights: our Right to the Dominion of the Sea, and the Dignity of the British Flag: The Laws and Regulations for the Government and Oeconomy of his Majefty's Navy: And the Bufinefs and Management of the feveral Royal Yards and Docks in this Kingdom. To which are added, our Right and Title to the British Colonies in North-America: And an Abstract of the Laws now in Force for regulating our Trade and Commerce. Illuftrated with copper-plates. By John Entick, M. A. Folio. l. 15s. Manby, &c.

N this diffuse and bulky performance the Compiler professes to exhibit a compleat view of the rife, progrefs, and prefent ftate of the British Marine: he feems, however, to have been more industrious in accumulating, than fcrupulous in selecting his materials. He appears to have admitted into this work, without much regard to elegance, method, or connection, whatever fell in his way, that had any relation to the various subjects he treats of: hence the volume is chiefly composed of Statutes, Acts, and Debates of Parliament; Charters granted to the feveral Trading Companies; ftale Relations of Voyages, Difcoveries, and Sea-fights; copies of Orders, Inftructions, or Commiffions to different Admirals and Commanders; large excerpts from Pamphlets, Journals, and Memorials, published occafionally by thefe laft, to exculpate themselves, or throw the blame of their feveral mifcarriages on others; Minutes of Councils of War and Courts-martial, &c. He has even inserted at large, and judiciously adopted for real Debates, those published in the Monthly Magazines.

By an indifcriminate ufe of fuch kind of materials, it will follow, that many curious and ufeful vouchers for hiftorical

facts

facts may be prefented to view; but we are of opinion, that, even when fuch authorities are authentic, they ought more frequently to be referred to, than admitted into the body of the work; as they may tire the patience of a Reader, without adding much to his knowlege; interrupt the narration; and deftroy the uniformity which is requifite in every performance intended to be read as an Hiftory, and not confulted as a mere Collection of mifcellaneous Traas.

We must likewife be permitted to remark, that this Compiler's language is often incorrect; nor has he been at much pairs to improve the phrafeology of thofe Authors, however obfolete, whofe relations he has thought proper to adopt: hence the ftile of the book is generally unpleafing, and often perplexed and obfcure; which, added to an extream prolixity, renders the perufal of it tedious and difguftful. Neither, we imagine, do the political reafonings, reflections, and remarks with which it is liberally interfperfed, add greatly to its value; as they are frequently trivial and common.

It must, however, be allowed, that fome parts of this volume, from the very nature of its fubject, are useful and entertaining. Memoirs of eminent Seamen; accounts of Engagements that established our power and reputation at fea; Hiflorics of Voyages, Difcoveries, and Settlements, the fources and fupports of our prefent grandeur;-thefe, however, deficient in the graces of elegant writing, muft, nevertheless, ftrongly engage the attention of every English Reader.

We may further remark, in favour of this publication, that in the modern trade of book-making, it is lefs injuftice to prefent the public with a collection of materials whence fome benefit may be extracted, than to obtrude upon it the fuperficial, flimfy, and curfory productions of fome of our modern Writers.

This work, containing 887 folio pages, clofely printed, is divided into feven Books; and thefe are again fubdivided into a number of Chapters.

Mr. Entick, in the Introduction, defcants on the advantages arifing from Navigation and Shipping; gives a long Differtation on our right to the Sovereignty of the Sea, with the laws and cuftoms thereof; a detail of the regulations and inftructions relating to his Majefty's fervice; the duties of the Commiflioners and principal Officers of the Navy Office, and of thofe in the management of the Yards or Docks; an abstract of the charge of building fhips of the feveral rates, their dimenfions, and quantity of fores; a lift of the prefent Admirals and Captains of the Navy,

together with the names of the Lord High Admirals, and Commiffioners for executing that office, fince the year 1673. These particulars, of little confequence to Readers in general, may neverthelefs be agreeable to Gentlemen who delight in circumftantial details. As to the pains he takes to vindicate our right to the Sovereignty of the Sea, he expends his ammunition, we apprehend, to little purpose. A powerful fleet will always command that refpect which is due; but should we be ever rivalled in that particular, by other nations, they would hardly admit of the validity of pretenfions founded on ancient claims and ufages. We fhall infert his account of the prodigious increase of our naval force, from the beginning of Queen Elizabeth's reign, to the prefent times.

The Marine of England was a long time before it arrived to its prefent grandeur. For in 1575 the whole royal navy confifted of no more than twenty-four fhips; the largeft of which, called the Triumph, exceeded not the burthen of a thousand tons; and the fmalleft, the George, was under fixty tons. And according to a furvey then made of all the shipping belonging to England at that time, the whole number. employed in the Merchants fervice, meafuring from forty to a hundred tons, amounted only to fix hundred and fixty-fix veffels; and thofe of a hundred tons and upwards, to no more ⚫ than one hundred and thirty-five. The whole of our naval force, computing the Queen's fhips, thofe the hired, and fuch as were fitted out at the expence of the Sea-ports and private perfons, to defend the coast against the Spanish invafion, in 1588, amounted only to one hundred and forty-three ships, including tenders, ftorefhips, and veffels of all fizes. At the death of Queen Elizabeth, the royal Navy was computed at • fixteen thousand tons. During King James I's reign, naval architecture was greatly improved by the ftudy of the famous Phineas Pett; and the royal Navy, at his demife, was increafed to the burthen of twenty-three thoufand tons. And from this Æra, as our trade and navigation confiderably increafed, our fhipping was augmented in proportion, notwithftanding the great difcouragement which the mercantile part of the nation fuffered during the civil wars. For the Ufurper rightly judging the advantage a fuperiority at fea would give his politics over his neighbours, almoft doubled the national fleet, as the King found it at the reftoration: and the Dutch war which foon followed, occafioned fo large an augmentation, that Lord-Keeper Bridgeman, in 1670, reported, that for ten years paft, the annual charge of the navy amounted to half a million. In 1678 the royal Navy confifted of eightythree fhips, of which fifty-eight were of the line of batte: Oo 3
