94 The Microscope. 



The immediate fixing of specimens to the slide, the centering of 

 specimens and the use of the freezing microtome are clearly ex- 

 plained and show plainly that the doctor has fully tried all the 

 plans before indorsing or making them public. Then follows a short 

 chapter on the method of demonstrating the tubercle bacillus. 



We have tried the method recommended, but find it somewhat 

 unsatisfactory because of the difficulty of maintaining the tempera- 

 ture at llO'' Fahr. However, the slides that the doctor makes with 

 this method are among the best that we have seen. 



The Therapeuticat. Drinking of Hot Water, its origin and use- Origin 

 OP The Salisbury Plans op Diet in Chronic Diseases with direc- 

 tions FOR preparing BEEF PULP, by Ephraim Cutter ' M D New 

 York: W. A. Kellogg. 1886. pp. 34. , ., 



Dr. Cutter is well known to the readers of this journal as a 

 clear, terse writer, thoroughly familiar with the subject with which 

 he deals. The first of the papers in the little book before us has 

 already met with an appreciative reception, as it has been repub- 

 lished some five or six times. The second paper on the Salisbury 

 diet plan, although written as long ago as 1880, will be read with 

 pleasure by practitioners and laymen, for it is full of interesting and 

 valuable suggestions. We differ materially, however, from the state- 

 mant of Dr. Salisbury in " Appendix B," that measles is produced 

 by the vegetation of decaying wheat or rye straw, or that the in- 

 oculation of this fungus gives immunity from the real disease. This 

 theory was, during the late war, held to be true, but subsequent ex- 

 periments proved it fallacious. 



Annual Report op the Curator of the Museum op Comparative Zoo- 

 logy, at Harvard College, 1885-86. 



We are glad to note, in this report, the increased interest that 

 is being taken by students and the public in the subject of Zoology. 

 The Agassiz Museum is already too small to accommodate the stu- 

 dents who apply for instruction on special work. 



The Microscopic Structure op a Human Tooth, together with some 

 Unusual and Irregular Forms op Teeth, by C. H. Stowell, M. D.,

 of Michigan, etc. ; Chas. H. Stowell, publisher, Ann Arbor. Mich. ; C.

This work is issued in the form of an atlas and with the elegance 

 of an edition de luxe. Its object, as given in the preface, is two- 

 fold. " First, to give to the dental profession plain and definite 

 statements concerning the minute structure of the human teeth, and, 

 second, to place on record some of the specimens from the unique 

 collections of Professors Ford and Taft." To do this, careful and 

 detailed dravnngs were made by the author, and then were engraved
