logue does not merely give the names of the authors, it is also an index of subjects. But the great point about the library is its collection of periodicals. The authorities are striving to obtain every periodical medical publication ever issued, and they have already obtained them all with the exception of those given in the subjoined list. The papers contained in these publications have all been catalogued under both the authors' names and the subjects of which they treat. Anyone meeting with a rare case in practice and desiring to find out whether it has been observed before, or anyone wishing to write a complete paper on any medical subject, will thus save, by means, of this catalogue, the time and trouble which he now loses in looking through the indexes of all the periodicals, English and foreign. It is evidently most important for every worker in medicine that the list of papers should be perfectly complete. But the catalogue only gives the papers in the journals which the library contains, so it is the interest of every medical man that the collection of journals in the library should be, as far as possible, perfect. The authorities have done all in their power to render it so, but several numbers, or even series of periodicals are now out of print, and not to be bought. These can only be obtained by the help of medical men, who having them in their libraries, are willing to benefit medical science by either selling or presenting them to the National Medical Library. The catalogue of this library is really an international work; it will be an incalculable personal benefit to every writer on medical subjects, and we earnestly hope that every one of our readers, in whatever part of the world he may be, will do his utmost to aid the authorities of the National Medical Library to render their catalogue complete. We append a list of the periodicals they still require.

Reviews.

1. A Treatise on the Diseases of Infancy and Childhood. By J. LEWIS SMITH, M.D., Physician to the New York Infants' Hospital, &c., &c. Third Edition, enlarged, thoroughly revised, with Illustrations. London: H. K. Lewis, 1876.

2. Clinical Studies of Disease in Children, Diseases of the Lungs, Acute Tuberculosis. By EUSTACE SMITH, M.D., F.R.C.P. Lond., &c., &c. London: J. and A. Churchill, 1876.

WHEN a work like that of Dr. J. Lewis Smith arrives at the third edition it may be safely granted that its repeated appearance has established for it a claim to the possession of substantial worth, so that the book may be fairly considered almost independent of criticism. We may further allow that if this had been the first instead of the third edition of Dr. Lewis Smith's work, we should have gladly availed ourselves of the opportunity to point out in more detail its many excellences, and particularly to draw attention to the fulness of its information, the fairness with which the reasoning is conducted in relation to disputed questions, and the completeness and soundness of its therapeutical suggestions and recommendations. We must, however, observe that some important additions are made in the present edition, and we more particularly notice a very long and valuable article on cerebro-spinal meningitis, based chiefly upon the author's experience of the epidemic of this disease which occurred in New York during the spring of 1872. Dr. Smith regards this affection as most probably due to some general atmospheric cause, and looks upon it as little if at all contagious. The article on Diphtheria has also been in a great measure rewritten, and contains a very fair and full account of our present knowledge of that destructive disease. Like Steiner he is not disposed to give adhesion to the theory of its bacterial origin, but is inclined to look upon the demonstrated presence of those organisms in the tissues of sufferers from this disorder rather as an effect than as the cause of diphtheria. Like Dr. Steiner he holds on by the theory of an exudative and a diphtheritic croup, but he allows that the former is seldom

seen nowadays. He ingeniously suggests that the explanation of this fact may be that the poison of diphtheria which is now so common, constantly seizes the membrane of exudative croup, and, developing there, changes the original character of the exudation.

This argument seems to us akin in weakness to the old theory of change of type in disease, which was created to cover the retreat of the medical profession from the abuse of bloodletting. It seems to us that the first sentence of the article, viz. "Diphtheria is a disease of antiquity," removes entirely any force that might appear to be possessed by the reasoning. If the germs of diphtheria prevent the normal development of exudative croup, the latter disease surely ought never to have been seen since the days of Aretæus at any rate.

It appears to us that an easier escape from these difficulties is to accede to the doctrine that croup when accompanied by false membrane is nothing more nor less than laryngeal diphtheria. The work is perhaps a little loosely written, but it contains a very large amount of valuable material, and the results of very extensive practice. It is particularly good in the remarks upon the treatment of disease, which, though the most important, is often treated with little thoroughness in a systematic treatise. From its completeness and fulness we consider it is much better suited for student's text-book than Steiner's work, though it is not so accurate in its pathology.

Dr. Eustace Smith had already led us to expect good work from him by his book on the wasting diseases of children. We feel, however, that he has more than come up to the high expectations which that work originated by his Clinical Studies of Diseases in Children. By publishing this volume he has laid the department under fresh obligations to him. We have read the book with intense delight. Though one could have wished that Dr. Smith had been able to include a wider range of disease than he has found practicable in Clinical Studies, we receive the present contribution with gratitude in the double sense of thankfulness for mercies received and of anticipation of future favours. We hope this is not the last volume which we shall see come from his pen. He has taken up the classes of clinical diseases which are most especially common in childhood, and present the greatest difficulty to the student of pædiatrics, and he has managed his task with great ability and success. The cases included are well taken and admirably chosen, and serve very materially to impress the subject forcibly upon the mind of the reader, whilst they lessen the tedium that is apt to fall upon one when reading a systematic work. We commend for particular study his articles on Pulmonary Collapse, on
