Pathogenic Bacteria

" In a work of moderate size, the author has succeeded admirably in presenting
the essential details of bacteriological technics, together with a judiciously chosen
summary of our present knowledge of pathogenic bacteria. As indicated in the
preface, the work is intended as an elementary text-book for students of medicine,
but Part II., or Specific Diseases and their Bacteria, will readily commend itself
to a large class of practitioners who recognise the value of acquaintance with the
behaviour of the bacterial causes of disease, even without a technical knowledge
of bacteriology. It is no unfavourable reflection on the scientific character of the
treatise, moreoYer, to mention the fitness of this second part for the use of the non-
professional readers who may be interested in the science or in its bearing on
matters of vital general interest.

"In the Introduction the author has sketched briefly, but in a sufficiently com-
plete and very interesting way, the history of bacteriology. The chapter on Im-
munity and Susceptibility is a more than usually successful attempt to briefly out-
line the present status of this very occult study, and in the discussion of the
various theories presented, the author has not given undue prominence to any of
the tenets. Tuberculosis is considered at comparative length, and all the more
important relations of this subject have received attention in the practical way
best adapted to the class of readers to which the book is addressed.

"Numerous photographic plates illustrate the text in the description of the
various bacterial species. Of these photographs, many are very characteristic.
The author has adhered with considerable uniformity to an easy and correct style
of diction, which is so often lacking in the treatment of very technical subjects.
The work, we think, should have a wide circulation among English-speaking
students of medicine."—New York Medical Journal.

MAISCH'S Materia Medica.—Sixth Edition.—A Manual of Or-
ganic Materia Medica : Being a Guide to Materia Medica of 4he Vegetable
and Animal Kingdoms. For the use of Students, Druggists, Pharmacists,

thoroughly revised by H. C. C. MAISCH, Ph.G. In one very handsome 12mo
volume of 509 pages, with 285 engravings. Cloth. 10s 6d net.

" New matter has been added, and the whole work has received careful revision,
so as to conform to the New United States Pharmacopeia. The great value of
the work is the simplicity of style and the accuracy of each description. It
considers each article of the vegetable and animal pharmacopoeia, and, where
important, sections on antidotes, etc., are added. Several useful tables are incor-
porated. 5*— Virginia Medical Monthly.

" The best hand-book upon pharmacognosy of any published in this country.
The revision brings the work up to date, and is in accord with its previous high
standard.5-"—The Boston Medical and Surgical Journal.

" We can add nothing to our previous commendatory notices of this standard
text-book of materia medica. It is a work of such well-tried merit that it
stands in no danger of being superseded."—American Druggist and Pharmaceutical
Record.

Physician-in-Chief to Johns Hopkins Hospital, Baltimore, M.D., Small Svo.
Illustrated. Cloth. 6s net.

" The volume before us contains six lectures delivered before the post-graduate
course at the Johns Hopkins University, which have already appeared in the
pa^es of the 'New York Medical Journal.' The first two are devoted to
the stomach, the first dealing with tumours formed by the dilated stomach itself,
almost always associated with a nodular mass at the pylorus. Amongst the special
points to which he calls attention in reference to diagnosis may be mentioned the
