der the formation vacuoles, and the bacterium growing- on 

 its substance, lives on and multiplies. Reaction against 

 noxious influences in the ameba consists in regeneration, 

 digestion, expulsion. This type is followed by all animals, 

 but the process is more complicated in higher organisms. 

 Following up this line of research, Dr. Knut Hoegh of 

 Hamline University finds inflammation to be nature's pro- 

 tection against infection, a friend and not an enemy to be 

 fought. 



Kentucky School of Medicine. — Each lecture room is 

 furnished with a powerful electric light, magic lantern or 

 projector, provided with stereoscopic, polariscopic, spec- 

 troscopic, and microscopic attachments, with a set of mi- 

 croscope objectives which yield brilliant results. Minute 

 microscopic objects can by this means be shown to hun- 

 dreds at once. A larg-e assortment of lantern photographs, 

 micro-photographs, and microscopical specimens are avail- 

 able to students. Recognizing the importance of the study 

 of Microscopical Anatomy, they have made additional im- 

 provements in the. laboratories. The course given con- 

 sists of demonstrations with the microscope, of lectures 

 and practical work in the methods of preparing, hardening- 

 staining, and section-cutting-, and mounting specimens for 

 the microscope. Students make permanent mounts, and 

 are furnished with all the necessary material, except the 

 slides and covers used for their individual collections. 

 Practical laboratory work following the lectures and dem- 

 onstrations constitutes the course in bacteriology. Ample 

 room, a superb and up-to-date equipment of microscopes, 

 dry and steam sterilizers, thermostats, plate culture appa- 

 ratus, etc., enable the student to do most excellent work. 

 Cultures of all the most important bacteria, and many of 

 the rarest, are kept constantly on hand. The student is 

 taught the methods of sterilization, of pure cultivation, of 

 the examination of colonies in cultures and of the micro- 

 organisms under the microscope. The student is drilled 

 to practical mastery of all that is needed by the modern 

 physician. The laboratory is open the entire year, and 

 opportunity is given advanced students and graduates to
