the clearest and ablest expositions of the subject. We believe that such a revision was sorely needed, since there have always been better books than "Green's Pathology" on the market. The chief additions are to be found in the chapters devoted to the Animal Parasites, the Autointoxications and Diseases of the Nervous System. Rewritings are noticeable at many places, and the form of presentation has been improved.

Pathogenic Micro-organisms, including Bacteria and Protozoa. A Practical Manual for Students, Physicians and Health Officers, by William Hallock Park, M.D., Professor of bacteriology and hygiene, University and Bellevue Hospital Medical College, and Director of the Research Laboratory of the Department of Health, City of New York. Assisted by ANNA W. WILLIAMS, M.D., Assistant Director of the Research Laboratory. Second Edition, Enlarged and Thoroughly Revised, with 165 engravings and 4 full page plates. Lea Brothers & Co., New York and Philadelphia. 1905.

The thoroughness of this work belies the author's estimate that it will be used by students only, such at least was his aim in its writing. We venture to suggest that it will be a hand book for bacteriologists as well. For one beginning the study of bacteriology other books will be found more accessible, and will be more readily understood, for the advanced student however it will give perfect satisfaction. The chapters devoted to the Protozoa (Part III) are gladly received, they are surprisingly complete and constitute the greatest advantage obtained by the revision of this book; the completeness found here, would we fear tend to confuse the average medical student, for there is much that he neither could nor need assimilate in his medical course. This section, however, is almost unique in its presentation and merits the highest praise; why it is omitted from so many good textbooks on bacteriology, even those written to-day is a question.

In the death of Dr. Gregory, the Medical Department of Washington University mourns one of its most honored teachers. Born at Hopkinsville, Ky., he began the study of medicine at the age of 16 with his uncle Dr. Thomas, in Cooper Co., Mo. Somewhat later he took a course of lectures in Louisville, Ky. He was married in 1845 and practiced medicine in Morgan and Cooper Counties, Mo. In 1850 he came to St. Louis and in 1852 was appointed Demonstrator of Anatomy in the St. Louis Medical College, which he served for more than fifty years, being made Adjunct Professor of Surgery in 1866 and Professor of the Principles and Practice of Surgery and Clinical Surgery in 1870.

Many other honors came to him. He was elected to the presidency of the St. Louis Medical Society in 1871, of the Missouri State Board of Health in 1883, of the Missouri State Medical Association in the same year, of the American Medical Association in 1887 and of the St. Louis Surgical Society in 1892. He was intimately connected with St. Louis Mullanphy Hospital, serving it with love and fidelity from its foundation until his death.

Of his influence as a teacher it is difficult to speak too

highly. Two generations of students sat at his feet and had the benefit both of his intellectual and moral influence. During the years in which antisepsis and asepsis in surgery were on trial he was one of the most earnest champions of modern ideas and the spread of proper surgical ideas in this portion of the country owes much to his influence. He will be chiefly remembered by his pupils, however, for the high professional ideals which he inculcated both by precept and by example. An earnest opponent of whatever savored of commercialism in medicine, his upright and unselfish spirit scorned mere money-making, and his pupils were better men as well as better physicians for having come under his influence. He will be remembered with love and veneration by all of our alumni.

AN OPERATION

FOR

STRAIGHTENING THE

NASAL SEPTUM.*

BY GREENFIELD SLUDER, M.D.

(From the Nose and Throat Clinic, O'Fallon Dispensary, Medical Department of Washington University.)

Even at the present time when the older operations for straightening the nasal septum in adults seem to have been superseded by the operation of Professor Killian (the sub-mucous resection of the deformed parts), there is still a need for an operation suited to the conditions existing in children; one that can be performed quickly and easily, and in which there shall be the least possible interference with the integrity of the septum which has to play so important a part in the subsequent growth and development of the nose.

In the course of the past eight years I have performed the operation now to be described twenty-four times in cases of the highest grade of deflection of the septum; five of these operations were on adults, and nineteen on children.

In twenty of the cases the crest of the deformity followed a horizontal or nearly horizontal direction, in four it was vertical or nearly vertical.

One case in a youth of eighteen, and a foot-ball player, was operated on for a horizontal deformity; after four months he sustained an injury which resulted in a vertical deformity which I saw, for the first time, six months later.

As is well known a capital difficulty in getting satisfactory
