laboratory of Glbemistrv, llbbarmacy ano Uoricologv I-IE Chemical Laboratory occupies the whole of the third Hoor of the new building QIOOX45 feetj, and has accommodations for I almost two hundred students. i Since it is the outcome of much experience, careful investi- ' gation and planning on the part of Prof. Haines, one would l naturally expect to find it a model laboratory, and such it is acknowledged to be by those best fitted to judge. The ceiling is high, and desks and other woodwork are of pine with hard oll finish: this, combined with an abundance of light from windows opening north, south and east, make every one of the 192 desks a desirable place to work. Aside from the main laboratory, Prof. Haines has two rooms in the south- east corner htted up for his own private use, and it is there he carries on his various investigations. A Taken altogether, the Chemical Laboratory, although not the most expen- sive, is one of the most complete and convenient that can be found anywhere in the country. g esoaia JBacterioIogicaI laboratory The room devoted to this department is 42x27 feet in size and well lighted. There are private desks and lockers for fifty men to work in one class. In a smaller room are similar desks where ten students pursuing special work can be accommodated. The laboratory is well supplied with all necessary apparatus, including sterilizers, incubators, oil immersion objectives, etc. Each student is supplied with the outfit required for the work of the course. The aim in the course work is to give such knowledge that the student may prosecute the study further at his leisure, but more especially that he may be able to apply this knowledge into the various branches of pathology and practical medicine. This may be accomplished if he obtains a clear idea of bacteria as causes of disease, and the measures to be employed in prophylactic and curative efforts. The work is not simply demonstrations, but each step is carried out by the individual students. Considerable time is spent on technique, on preparation of various nutrient media, principles of sterilization, staining processes, prep- aration of plates and rolls, etc. A thorough systematic studv of a few bacteria is made, notes and drawings being prepared on the same. Of the pathogenic bacteria only the most common are studied, and preferably those whose recog- nition is of practical value in diagnosis, z'. a., bacillus tuberculosis, gonoccus, bacillus diphtherife. The bacillus of typhoid fever is compared with the colon bacillus, and the spirillum of Asiatic cholera with those resembling it. The bacillus diphtheria? is studied on various media for its varying morphol- ogy, and the diagnosis by the use of Loefilers blood serum mixture is demon- strated. The class works six hours a week for six weeks. The laboratory is in charge of GEO. H. VVEAvER, lVl. D., assisted by XY. C. F. XYi'r'rE and -I. H. NICHOLS. 55

1DistoIogicaI ano llbathological laboratory The classes in Histology devote the first few weeks to the study of fresh teased tissues, as well as some of the commoner foreign substances occasionally found in specimens, as wool and cotton libres. When familiarity with the microscope has been attained, and a knowledge of elementary tissues. as tibrous tissues, bone, cartilage, blood, etc., the study of more complex structures is undertaken. Each member of the class mounts tifty specimens. These have been stained in bulk and cut in parafline. Many of these sections are from injected unstained tissues, and are utilized to teach the vessel distribution. In some double injection has been done, whereby arteries appear red and veins blue. These sections cover all the important organs and structures, and many of those of less importance. Instruction is so arranged that it shall go hand in hand with lectures on Physiology. ln this method function and minute anatomy are obtained together. The size of the classes tforty to sixtyj has so far prohibited further instruction in technique, but each class is shown apparatus and the methods used in the preparation of specimens. The course lasts throughout the year, each class working two hours a week. Drawing, while requested, is not made a special feature of the work. lt is valuable to impress the mental picture obtained. Especial stress is laid upon landmarks of different tissues, so that proficiency in the iden- tification of tissues can be obtained. All Freshmen are urgently requested to take the course in Histology the first year, as the early knowledge of minute anatomy is a valuable basis to many other branches of medicine. The work in microscopical Pathology, like that in Histology, extends throughout the year. Fifty sections from tissues that were imbedded unstained in celloiden are stained by each member of the classes and mounted. The method of staining is the double Haematoxylin and Eosin, with acid alcohol to destain. The first of these specimens are used to teach general pathology, a thorough systema- tized knowledge of this being the one object kept in view throughout the course. The latter part of the course comprises: 113 Examination of sections from special lesions that bear upon internal medicine, 14. tr., typhoid ulcer, unresolved pneumonia, etc. C23 The microscopical study of tumors, many varieties being examined. Q33 Microscopical urinalysis taken in con- nection with the study of morbid Histology of the kidney. No one is supposed to take Pathology unless well grounded in Histology.

There is desk room for sixty students, giving each a separate set of the apparatus neces- sary for the work to be done. A scale-table containing twenty prescription balances, each furnished with a set of dry and metric weights, has also been provided. Each member of the Freshman class works in the laboratory two hours per week through- out the term. The works consists of handling the prepared and crude drugs, thereby famil- iarizing the student with their physical propertiesg making some of the simpler pharmaceutical preparationsg writing prescriptions, thus giving practice in the proper form of a prescription, the official names and their proper abbreviations, incompatibilities of all kinds, compounding prescriptions of all classes.
