to render our own useful, some method is necessary for concentrating the result of these labours. True-then, as we before remarked, nosology is a catalogue raisonnée of diseases and of authors; and, if so, we shall leave every writer to chuse his own mode, and the public will judge which is the handiest. For our parts, we have no objection to any, excepting as they endanger decision in the practice of acute diseases, and in chronic or local complaints encourage indolence, by substituting terms for well-defined descriptions. On the influence of nosology in acute diseases, we have already said enough; in chronic complaints, we shall find ample opportunities when we come to notice the various parts of the arrangement before us. Mr. Good concludes his prolegomena by some remarks on the oriental synonyms and writers. Of the accuracy of these it is not in our power to judge, nor have we, as on all other occasions, consulted those who might give us information. The truth is, we were unacquainted with any medical gentleman who pretended to a critical knowledge of those languages. We felt, indeed, at first, some alarm from learning that "no one ought to pretend to a scientific acquaintance with cutaneous diseases, who has not studied Serapion; nor to a practical history of small-pox, who has not read the pages of Rhazes." Yet it appears, on the same authority, that Willan was unable to read Serapion, and we have no proof that Sydenham knew any thing of Rhazes; yet the honest Boerhaave advised his hearers to read Sydenham, plus quam decies. Probably Boerhaave might be ignorant of the treasures contained in Rhazes. Such was not, however, the case with Mead, who procured Latin translations of his work from two different sources, and collated them with the highest authority in his days; yet, after all, he only speaks of Rhazes as containing an imperfect detail of what he knew before, and even demands ample "allowance for time and place.' This is very different from his language when speaking of his countryman Sydenham-of whom he remarks that he was the "first who divided that disease into different stages, and gave the method of cure in each.” Besides the English translation of Rhazes, by Mead, we have one in Latin, by Mr. Channing, an apothecary of considerable practice in London. This gentleman, after a laborious study, repaired to Oxford, that he might have a more perfect acquaintance with oriental literature, and was so ready at Arabic, that his private memorandums were all made in that language. His translation of Rhazes is from a MS. at Leyden. He has also added the Almanzor, but from from authorities less certain. After the perusal of these translations of the best Arabic works in physic, we feel less regret at our ignorance of that language, especially when we reflect on the first aphorism of the Grecian sage, and that we have heard profound scholars, not destined for medicine, regret the time they had lost in the acquisition of oriental literature. The best part, as far as relates to science, is well known to consist of translations from the Greek. Even Rhazes, in this celebrated work, would gladly have discovered small-pox in the writings of Galen,-an attempt about as successful as the researches of a modern writer into Hippocrates for a similar purpose. Whilst we thus submit, perhaps it will be said from necessity, to our ignorance, we feel the more obliged to those who have undertaken a labour from which we have shrunk. Etymology cannot be without its uses, and as Mr. Good has furnished us with the oriental words in their proper characters, we trust, in a future edition, he will imitate Mr. Tooke in furnishing us with alphabets, or an alphabet, with directions how to use it. "Occasionally," we are told, "where the Arabic names are also Persian or Turkish, the author has added the initials, or other marks of these cognate tongues, and, in a few instances in which they are peculiarly expressive, he has also superadded the Persian or Turkish names, even though different from the Arabic. At times, indeed, the Arabic writers themselves employ a Persian or Syriac term, for several of them were of Persian or Syrian birth, and in such cases the author has also indicated the proper origin: all which has been a labour of no small trouble, from the novelty of the attempt, and the difficulty of procuring medical Arabic and other eastern books that would answer the purpose." It is impossible to doubt the author's diligence, nor can we wonder if, in the midst of such multifarious inquiry into languages, he has occasionally become obscure in his own. We shall here conclude our remarks on the introductory part of the work. The reader may think them long, but we can assure him they are much shorter than our first MS. The extracts are, indeed, more copious, as we are always fearful of doing injustice to an author by partial quotations, or by offering his opinions in words at all different from his own. Where we differ from him, this is particularly necessary; and, where we agree, there is always danger lest by transferring his thoughts into our own words, we should seem to claim his discovery for our own. It is, however, time time we should enter on the Nosology itself. The following are the "Series of Classes and Orders. CLASS I. CELIACA-Diseases of the Digestive Function. II.-SPLANCHNICA-Affecting the Collatitious Viscera.” The six other classes follow, with their orders, after which is a "Table of the Affixes and Suffixes that chiefly occur in the ensuing Nomenclature, with the Senses in which they are used. We have transcribed this as a useful table, and which may be readily referred to in reading our future extracts. Only Only one objection occurs to us, which it will be time enough to notice when we arrive at a passage in which the term is introduced. In examining the execution of the work, we had determined to proceed seriatim. But, as this might prove less interesting to ourselves, and, as we apprehended, to our readers, after a minute attention to the first article, we contented ourselves with those which appeared more connected with nosological controversy, and some of which having come lately before us would be more fresh in our readers' recollection.

In the compounds of dos, odontia is common to the Greek writers, as Teodória, &c." [Here follows a note concerning the progress of dentition in the temporary and permanent teeth.] "1. y O. dentitionis, Adultorum.—The cutting of these teeth is often attended with peculiar pain and inconvenience, especially when the process takes place very late, and consequently after the jaw-bones have ceased to grow: for we have in this case often a want of sufficient room, and, in the upper jaw, the tooth on each side is frequently obliged to grow backward, in which position it sometimes presses on the anterior edge of the coronoid process in shutting the mouth, and consequently gives considerable pain. When the same fact takes place in the lower jaw, some part of the tooth continues to lie hid under that process, and covered by the soft NO. 223. Hh ♪ Senilium.

"For the most part, the teeth shoot forth irregularly, and few in number, so as to be of little benefit, and sometimes more injurious than useful, by preventing the approximation of the callous gums, which till now had been employed as a substitute for the teeth. In one instance, though only in one, Mr. J. Hunter informs us, that he was witness to the reproduction of a complete set in both jaws: and he supposes that in all these cases a new alveolar process is formed, as in the preceding sets. From this circumstance,' says and another that sometimes happens to women at this age, it would appear that there is some effort in nature to renew the body at that period.' he, "He alludes to a return of menstruation; but there are other facts, and of perhaps a still more singular kind, that point to the same conclusion. The author once attended a lady who cut several straggling teeth at the age of seventy-four, and at the same time recovered her sight so completely as to throw away her spectacles, which she had made use of for twenty years, and to be able to read with ease the smallest print in the newspapers. In another case that occurred to him, a lady of seventy-six cut two molares, and at the same time completely recovered her hearing, after having, for some years, been so deaf as to be obliged to feel the clapper of a small hand-bell, which she always kept by her on a table, in order to know whether she made it ring. "One of the most singular instances on record is that given by Dr. Slare in the Phil. Trans. vol. xxvii. 1713, as it occurred to his father. At the age of seventy-five, he renewed an incisor lost twentyfive years before; at seventy-seven, he renewed an incisor to supply a similar vacancy; at eighty, all his teeth were hereby rendered perfect; at eighty-two, they all dropped out successively; two years afterwards they were all successively renewed, so that at eighty-five he had an entire new set. His hair simultaneously changed from a white to a dark hue, and his constitution seemed somewhat more healthy and vigorous. He died suddenly at ninetynine or a hundred. "2. Odontia dolorosa.
