of Natural History, by whom they were performed without 

 remuneration till 1882. In 1883 the chair of Botany was 

 established by the appointment of Professor D. P. Pen- 

 hallow, B. Sc., under whom practical and additional courses 

 and laboratory work have been introduced, to which it is 

 desired more particularly to refer in the present paper. 



In 1886 an additional course in the third and fourth years, 

 embracing practical histology, was instituted for the benefit 

 of those students who evince a special taste for such work, 

 and desire to carry it on beyond the ordinary course of 

 the second year. Accommodations for this purpose were 

 secured in the Peter Eedpath Museum, but within the past 

 two years the combined growth of the botanical collections 

 and of a greater desire for instruction in this branch, 

 resulted in the room then occupied being wholly inadequate 

 to meet the requirements of the work. The removal of 

 the Faculty of Applied Science to new quarters, left vacant 

 a suite of rooms in many respects well adapted to the pur- 

 pose of a laboratory, and which were granted by the Board 

 of Governors for this use. They are on the upper floor of 

 the main building, and thoroughly lighted, the aspect being 

 northern. The problem then was to convert these rooms 

 to the required purpose with a minimum of expense, 

 utilizing, as far as possible, such furnishings as were on 

 hand. This has been accomplished in such a way as to 

 meet present requirements in a very satisfactory manner, 

 although were a laboratory to be constructed de novo, various 

 changes from the present form and arrangements would be 

 made. By reference to the plan, the details will be made 

 clear. Boom C originally consisted of two apartments 

 which were thrown into one. Boom A is used as a private 

 office and laboratory. It measures 11 X 15.5 feet. Boom 

 B, 7 X 15.5 feet, contains two series of shelves, 1, 1, with 

 drawers and cupboards for the storage of apparatus, 

 reagents in bulk, general supplies and balances. Boom C 

 is the general laboratory, measuring 15.5 X 56.5 feet, with 

 an ell room, 19 X 21 feet. Access to these rooms is gained 

 through the halls D, E, which open out from the main 

 hallway of the building.
