glass-ware, aud apparatus in immediate use. There are 

 tables with gas and water supply; a sink with hot water 

 apparatus and cleated shelves for drying purposes; and dry- 

 ing and constant-temperature ovens. Accompanying the 

 reagent case is a card catalogue, which indicates very nearly 

 the arrrngement of reagents, so that the time taken to find 

 one is reduced to the minimum. 



Among the pieces of apparatus in the room are auxanom- 

 eters, clinostats, electric and mercuric thermo-regulators, 

 hot stages, dialyzers, pressure regulators, chemical, torsion, 

 and ordinary balances, dynamometers, an electric motor, 

 transpiration tubes, etc. 



The bacteriological room has a south and east light, and is 



fungi, and physiological subjects. The library is carefully 

 catalogued. 



The herbarium contains both phanerogams and crypto- 

 gams, parasitic fungi being specially well represented. 



In the store room are kept the supplies not in immediate 

 use. Leading from the store-room is the dark room for 

 photographic work ; this room being supplied with gas, 

 water, a specially arranged sink, aud the chemicals and ap- 

 pliances needed in the work. 



A small greenhouse extends south from the station, its 

 main room opening directly from the laboratory and on the 

 same level. This room is fitted up with tables and benches 

 upon which apparatus can be placed when the student is 



fitted up with the latest appliances; such as steam and dry- 

 air sterilizers, germination ovens, bulb and ordinary culture 

 tubes, and all the various paraphernalia used in bacterio- 

 logical work. There is a large table with sink, having a 

 water supply, and cases of drawers for supplies of cotton, 

 agar, gelatine, cages, etc., a case of stains, and a large hood 

 with water supply in which the steam sterilizers are 

 placed. 



The library and herbarium on the opposite side of the 

 general laboratory to the bacteriological room contains the 

 standard works, and as Dr. Arthur's private library is kept 

 here besides, there are many valuable and rare works to 

 wbich one doas not usually have the good fortune to have 

 access. There is also a good supply of botanical journals 

 both ^n English and foreign languages. The library is speci- 

 ally well supplied with works on plant diseases, parasitic 



working with the living plants. The smaller room is on a 

 lower level, and is kept at a lower temperature than the 

 main room. Experiments can thus be carried on with plants 

 at different temperatures. There are also in this room a 

 floor tank for aquatic plants, and steam-heated cutting beds. 

 Both rooms are heated by steam. The greenhouse forms a 

 very useful adjunct to the laboratory.- 



The laboratory in the Station is entirely separate from the 

 University laboratory, the latter being under the direction of 

 Dr. Stanley Coulter; the work there is in systematic and 

 sti'uctural botany. The students in Dr. Arthur's laboratory 

 who do the physiological and bacteriological work are juniors 

 and seniors who have elected botany aud have done the sys- 

 tematic and structural work previously. There are also 

 post-graduate students who are doing original work.
