BOTANICAL LABORATORY. 



In the botanical laboratory instruction is given in the prac- 

 tical study of the structure, development, and physiology of 

 plants, and opportunity is offered for investigation in cellular 

 biology, in embryology, physiology, and pathology. Provision has 

 also been made for graduate students entering upon the profes- 

 sional study of forestry to carry on special work in botany. 



The library contains approximately 3,000 bound volumes of 

 exclusively botanical books, 2,000 volumes of which are shelved 

 in the laboratory. These include the leading American, English, 

 German, and French botanical periodicals, among which are the 

 Annals of Botany, Botanical Gazette, Journal of the Linnaean 

 Society, Botanische Zeitung, Botanisches Centralblatt, Botan- 

 ischer Jahresbericht, Flora, Jahrbucher fur wissenschaftliche 

 Botanik, Annales des Sciences naturelles, Bulletin de la societe 

 botanique de France, Annales du jar din botanique de Buitenzorg, 

 and others. 



The laboratory comprises four large rooms for general work, 

 five smaller rooms for the work of instructors and investigators, 

 a room for alcoholic material, a dark room and store rooms. The 

 section assigned to morphology and cytology is provided with 

 high grade microscopes, cameras, and polarizing apparatus; Cam- 

 bridge, Minot-Zimmerman, Jung, and freezing microtomes; ster- 

 ilizers, means for embedding, Wardian cases, aquaria, and pho- 

 tographic apparatus. The equipment for physiology, besides 

 rooms provided with chemicals and general apparatus, includes 

 a dark room with constant temperature, incubators, sterilizers, 

 refrigerator, horizontal microscopes, balances, thermograph, 

 barometers, auxanometers, klinostats, and centrifuges. The heav- 

 ier apparatus is driven by electric and water motors. A plant 

 house affords space for work under glass. 



The University herbarium, with 100,000 specimens, and the 

 botanical garden include a large proportion of the plants indi- 

 genous to Michigan, besides many foreign species. The collec- 

 tion of fungi includes Briosi and Cavara's Funghi Parasiti, Sey- 

 mour and Earle's Economic Fungi, Ellis's North American
