MAST ON PLANS FOR A BIOLOGICAL LABOKAToKY. 207 



material, generally speaking, that can be supplied the more satisfactory 

 will be the work of the student. As a partial source of such material 

 we have planned a conservatory. The conservatory is to ])roject eight 

 feet beyond the building to the east. It is to be twelve feet 

 wide and thirteen feet long, and will have a cement door with 

 a drain, and glass roof and sides. It is to be supplied with an 

 aquarium two feet wide and four feet long with water and drain- 

 age connections. The conservatory is not only to serve as a source 

 of supply of fresh material but also as a suitable place for carrying on 

 physiological experiments, which require strong sunlight, a humid atmos- 

 phere free from injurious gases, and a comparatively constant tempera- 

 ture. Such experiments, however, that require more sunlight than can 

 be had in the conservatory, can be performed in the lecture room which 

 is in connection with the laboratory and faces the south. Certain land 

 plants, as well as some aipiatic plants and animals demonstrating ecolog- 

 ical principles may also be reared in the conservatory, although most 

 ecological work must be carried on out of doors. 



In physiology, particularly |)lant physiology, it is necessary to perform 

 some experiments in the absence of light. For this purpose, and in order 

 to carry on work in photography, which is constantly becoming of 

 greater biological importance, we are to have a dark room 7x10 feet in 

 the laboratory. The dark room will be supplied with water and non- 

 actinic light. In preparing chemical compounds and cooking solutions 

 of various kinds, a hood is desirable. We will have one 2x7 feet, large 

 enough to accommodate three students at a time. It will be supplied 

 with water and gas. 



As above stated the museum will occupy the third floor of the building 

 in which the laboratory will be situated, consequently the museum and 

 laboratory will be in close connection, so that most of the prepared 

 specimens can be kept in the museum within convenient reach of the 

 laboratory. But even under such conditions, it will be desirable to have 

 a case for specimens, preparations, and models in constant use in the 

 laboratory. Our laboratory will be provided with a small one 2x6 feet. 

 .This case should be much larger if a laboratory is not in close connec- 

 tion with a museum. As a convenient place for keeping chemicals, 

 stains, dissections, glassware, etc., not in constant use, we are to have 

 a store room GxlO feet. The store room is to be in direct connection both 

 with the laboratory and the lecture room. Where human physiology is 

 taught by the text-book method, it is especially desirable to have the 

 store room in direct connection with the lecture room in order that 

 preparations for demonstration can readily be gotten to and from the 

 lecture room. The lecture room is also in direct connection with the 

 conservatory, so thai ]»lauts used for demonstration can be easily pro- 

 cured. 



A lecture room is not absolutely necessary in connection with a 

 biological laboratory; lectures and quizzes can be given in the laboratory. 

 A lecture room, however, has certain advantages: First, It is much 

 more satisfactory both to students and instructor, in case of lectures 

 and quizzes to be in a small room free from apparatus, and Second, It 

 is often advisable to have work going on in both rooms at the same time. 

 Our lecture room will be 24 feet wide and 26 feet long, large enough to 

 seat forty students. It is to be supplied with large blackboard surface,
