General Information. 



The laboratory of the School of Botany is temporarily located at 

 1724 Washington Avenue, and a good working library, containing the 

 usual laboratory manuals and periodicals, with memoirs on subjects 

 likely to be studied, is kept in the laboratory for reference. This is 

 being constantly added to, and will be made as complete as possible in 

 any department of botany in which advanced students present them- 

 selves. The herbarium of the school, now being formed, contains 

 already about 14,000 sheets of specimens, and will include as complete 

 a collection as can be made of the wild and cultivated plants of the re- 

 gion about St. Louis. Full sets of duplicate specimens are supplied for 

 the use of students of particular groups of plants. Advanced students 

 will also have the privilege of consulting, under certain restrictions, the 

 excellent herbarium and library of the Botanical Garden, including the 

 Bngelmann herbarium and library, as well as several sets of Ftmgi 

 exsiccati and the private cryptogamic herbarium and library of the pro- 

 fessor. 



Material for laboratory use, and for the illustration of lectures, is 

 furnished in abundance by the Garden, which, with its greenhouses and 

 arboretum, is open to students of the School of Botany for all necessary 

 purposes of study. In case duplicate herbarium specimens which have 

 been studied, are desired by members of the class, they may be retained, 

 if application is made at the beginning of the course, and are charged 

 for at cost. Where alcohol and other expensive substances are used in 

 quantity, as in work on bacteria, a special charge for material used will 

 be made a* the end of the course. 



The instrumental equipment of the laboratory includes one micro- 

 scope by Zeiss, with a working series of objectives from AA. to 1-18 

 inch homogeneous immersion, and accessories for spectroscopic studies 

 and work with polarized light; ten microscopes by Leitz, with the ob- 

 jectives needed for the best botanical work (including nine oil immer- 

 sion 1-12 in. lenses, one 1-16 in. oil immersion, and one 1-20 in. oil 

 immersion), polariscope, camera lucidas of several patterns, etc. ; 

 seventeen dissecting microscopes, mostly by Bausch and Lomb ; and a
