Not content with the great success which the practice of inoculation hath mee with against the Small-pox in moit pa'ts of Europe, the Au. thor of this letter is for eradicating that terrible disorder entirely. He is indeed by no means of opinion, with most of the faculty, that this diltemper is a necessary evil to which almolt every person is naturally liable. He is far from thinkingit proceeds from a germe, or a virus, lodged in the blood, and which we bring with us into the world. According to Dr. Casimir, che variolous fever is produced by the same causes as produce every other inflammatory fever; and nothing more is necessary, to prevent the inflammation from breaking out in pullules, than to reduce the fever in the first instance. If the pustules appear to come to a head, says he, it is because we do every thing to favour their eruption, instead of checking it. Our Author is not the first physician by many, who hath entertaised this notion of the Small-pox; Dr. Krause of Leipfick, published a treatise on the same subject, but a very little while ago. This notion, however, appears to gain but little ground; and, indeed, it is to be apprehended that the advocates for it will never have a fair opportunity of putting it to the test of experience; especially since the progress of inoculation bath given fuch convincing proofs of its being å safe and easy method of paling through this horrid distemper, in permitiing the fever to come to a crisis by the suppuration of the puffules. There is another circumstance also attending this notion, which cannot fail to have a bad effect on the patient, who, in submitting to be inoculated, conceives he Mail for ever after be freed from the disor. der: whereas if the Small-pox be only a common inflammatory fever, no reason can be given why he should not be liable to the same fever again; as well as to other inflammatory disorders. This objection it Seems tared our good Doctor lo Itrongly in the face, that, in order to obviate is force, he is obliged to admit the fait, and own that there are many people who have had the Small.pox several times. He does admit, bowever, that in sach cales it generally comes under the difguise of the measles, the scarlet fever, &C. As a proof of this, he prescribes a method, by which a physician may convert the measles into the Small-pox, at any time, the patient chufe it. We cannot here coter into a controverty about any thing our Author hath ad. vanced ; but we greatly fear, that, fupposing him to be in the right, his remedy would, like many others, prove as bad as the disease.
Art. 3. Ratio facilis argue tuta Nafium curandi Polypos, &c. An easy and safe Method of curing the Polypus in the Nose.
8vo. Vienna. 1763. Mr. Pallucci, the ingenious Author of this little treatise, conceives that the Polyfus in the Nose is not an expansion of the picuitary membrane, as has been supposed by some ; because there is no mark in it of any diftiner organization. It is formed, says he, of a concretion of the blood, that oozes out after viclent bleedings at the nole. As a proof of this, he relates, that having extirpated a Polypus, and stopping the hemorrhage that succeeded too precipitately, another formed itself in a few days exactly like the former ; and which, being taken out and put into warm water, dissolved away. His method of extirpating these disagreeable concretions is somewhat different from those asually
practifed, and seems to be an improvement: but we cannot enter here

fcription du Cabinet du Roi. Tom X. Paris. 1763. The Natural History and Description of the Curiosities in the
Royal Cabinet. There are two volumes of this celebrated work, viz. the roth and 11th, lately published ; The former, however, is as yet only come to hand; and in this, we have the history and description of twenty foreign quadrupeds ; diftinguished in this work by the following names, the Oudatra, the Difman, the Pecari, or the Tajacu, the Roulette, the Rougelle, the Vampire, the Polarouche, the Petir-gris, the Palmiste, the Barbarifjue, and the Suise; the Tamanoir, the Tamandue, and the Fourmillier; the Pangolin, and the Phatagin; the Tatous, the Paca, the Sarigue or Opolum, the Marmose, and the Cazopollin. We need not acquaint the Reader with the obvious impossibility of our being particular on such a work as this; we cannot dismiss it, however, without inserting the following reflections of Mr. de Buffon, respecting the nature of quadrupeds in general.
• When we speak of a quadruped, the name alone seems to import an animal covered with hair; just as when we speak of birds or of filhes, their wings and their fcales present themselves to our imagination, as inseparable from their very being. But nature is so little acco dant with our ideas, that he seems to delight in contradiảing our moit general systems ; aitonishing us even more by her exceptions than her laws. Quadrupeds may be ranked, after the human species, in the firit class of animals; they are not superior nevertheless to all others in every respect, nor diftinguished from them by invariable qualities.
Their first characteristic from which they are denominated, viz. their having four legs, is common also to lizards, frogs, &c, which are so diflimilar to quadrupeds, however, in other respects, that they are juftly distinguished as a separate class of beings. Their second general property is that of being viviparous; but this belongs not exclufively to quadrupeds ; as it is equally common to all cetaceous animals. Their third general property of being covered with hair, which seems til less equ vocal, as it is the most apparent, is incompatible with the two former properties in many species of animals; which nevertheless cannot be separated from the order of quadrupeds ; for if we except th:s fingle quality, they resemble that order in all others. But as these apparent exceptions to the rules of nature are, in reality, only the shades of difference which the employs to unite beings, the most diftant in other respects from each other, we should never lose light of these lingular relations, but endeavour to observe them accurately whenever they present themselves. The Tatous, inftead of being covered with hair, have shells like tortoises, lobsters, and other crustaceous animals. The Pangolin is covered with scales, resembling those of fish. Again, por. cupines are armed with pointed quills without feathers, but the quill itself exactly resembles those of birds. Thus we see that, in the class of quadrupeds alone, and even in the most general and obvious property of such animals, Nature hath diversified her designs, in approaching three other classes very different; viz. birds, scale filh, and thellfilh.'
It is for this reason, continues Mr. de Buffon, that Naturalifts should

Dr. Storcke, viz. bemlock, has been publickly tried, and without luce cels, in above an hundred and twenty cases. As this, however, is only a second-hand kind of information, it may posibly not appear of luf. ficient weight, to deter the many poison-dealers which Dr. Storcke has fet to work in these and the neighbouring kingdoms, from the very exceptionable occupation of making such dangerous experiments. But it is confirmed from other quarters; and indeed were it not so, if we turn to our pharmacopeias, we shall find no such dearth in the Materia Medica, as to warrant this application to violent remedies.

der. By Antonio Genoveli, Profeffor of Moral Philosophy in the Royal Academy at Naples.
This work is divided into five paris, agreeably to the number of volumes. In the first the author undertakes to refute the doctrines of Fatalism; in the second Deism ; in the third Epicureanism, and in the fourth Libertiniím. Volume the fifth, contains four dissertations ; the first on the origin and primitive state of things : the second, on the eternity of the world ; in which the author attacks the Platonists and Peripatetics; the third treats of the nature of God; and the fourth of the origin of Phyfical and Moral Evil,
or the subjects of the three first of these differtations, it is impossible for the author to know much; and on the fourth it appears he does not know a great deal. In treating this lat, however, he gives a concise history of the various systems of religion and irreligion that have prevailed in the world. He examines into the metaphysical fyftems of King and of Leibnitz; and is of opinion that they are very visionary, and at bek mere paraphrases of Aristotle. We have no very great opinion, it is true, of the depth and folidity of this Writer; but we admire his courage, 'in daring to fand up for the reputation of that immortal Genius, which has of late years been as unreasonably depressed, as it was once ridiculously exalted. Our modern philosophers, inechanics, and experimentalists, may probably ftare at what we are going to affirm, because they never read Arittotle, or at least not with sufficient attention to understand him ; but we will venture to say that, if we excepe Lord Bacon, there never hath appeared a Genius for Physic:, fince the days of Ariflotle, that hath been even capable of underfanding the profound, and at the same time, the sublime truths, contained in the Physics of that celebrated antient. We adınit that he wanted innue merable data that we are possessed of; and that therefore half the experiment mongers in London know more than Aristotle. But what would they say, if it thould be shewn, that (among numerous inevitable errours, the effects of ignorance) the amazing genius of the Stagyrise suggelted those principles which the discoveries of succeeding centuries serve but to conform? We are far from depreciating the labours of those who can do nothing more than make experiments, or by din: of conllant enquiry, ftumble on discoveries : as far as they are accurate they are useful ; but we canazt help admiring infinitely more that fa.
