number of simple tripods; togetlier witli instruments, pipettes, reageiits, 

 and other necessaries. Microscopes, dissecting needles, and glasswjde, 

 are furnished by the laboratory, members of the class being held re- 

 sponsible for breakage or other injury. Razors or other instruments for 

 sectioning are not supplied by the laboratory for ordinary -work. 



A special bacteriological laboratory, providing tables for thirteen 

 workers, has been equipped "with sterilizing apparatus, brood-oven, 

 microtomes, and otlier accessories needed, and is in successful opera- 

 tion. It is hoped that ultimately another small laboratory may be de- 

 voted to advanced investigation in bacteriology, by trained physi- 

 cians. 



The working year for the School of Botany is divided into three 

 terms : the lirst beginning with the College year and ending at the Christ- 

 mas holidays; the second beginning immediately after New Years and 

 ending the last of March; and the third beginning about the first of 

 April and continuing until the Saturday before commencement. Classes 

 for the study of particular groups of plants, and special work ;[or 

 advanced students, are planned as the demand for them appears. 

 "Whenever it is practicable, a class for day or night work, in any branch 

 that can be taught with profit, will be formed on the application of six 

 persons. The elementary classes are so conducted as to require no pre- 

 vious knowledge of botany; but admission to advanced classes depends 

 upon a sufficient familiarity with the subjects to render the work profit- 

 able. Persons desirous of entering any class should present themselves 

 promptly at the opening of the course. Correspondence is invited from 

 those wishing special instruction.

Up to the present time, the number of special students in 

 the School of Botany has been small, and there is no indi- 

 cation that they will become numerous in the immediate 

 future ; but this is not a source of either surprise or disap- 

 pointment, for it was foreseen from the first. The work of 

 such students, though it has been chiefly of an elementary 

 character, has, I believe, been fairly satisfactory. But the 

 most important work that such a department of a Univers- 

 ity can accomplish, is that with advanced students, aiming 

 at the solution of some of the many problems that await 

 the investigation of specialists. From the first, it has been 

 the policy of the School of Botany to provide the amplest 

 facilities within its power, for such work; and books and
