building in general, is provided for b} T large 

 shafts in the wall, which, however, for the sake 

 of simplicity, are not fully indicated in the 

 plan. There are similar shafts for warming the 

 rooms with heated air. There are also numer- 

 ous steam-radiators for the coldest weather. 

 Besides the waste-pipes belonging to the sinks 

 and bowls, shown in the plan, there are many 

 extra waste-pipes with stop- cocks, to which, by 

 means of hose, water may be carried off from 



of place here. It is intended to serve primarily 

 as a laboratory of research, and secondarily as 

 an adjunct to the lectures on physiology in 

 the preparation of suitable apparatus and ex- 

 periments. Courses in ' practical physiology ' 

 are also given in the ' laboratory to the class 

 in sections of a convenient size, but no in- 

 struction in ' biology ' is contemplated. All 

 histological work proper is carried on in a 

 special department in another part of the build-

any apparatus which can possibly be set up in 

 any of the rooms. The sink in the north-west- 

 ern corner of the laboratory and the adjacent 

 basin (Bn) have both hot and cold water. 

 With one exception, the water-supply comes 

 directly from the ordinary cit} T pipes. The 

 exception is the chemical table against the 

 southern wall, which has an independent sup- 

 ply from the tank already mentioned, and there- 

 fore useful for hydraulic experiments. 



To avoid any misapprehension, a word as to 

 the purpose of this laboratory may not be out 



ing. It seems desirable to mention these 

 things more particularly, lest any one should 

 miss those features which are prominent in 

 some American laboratories of recent date. 



The centre of the room is occupied by a 

 large double case (GC), with glass doors on 

 both sides, intended to hold such pieces of 

 apparatus as are used in laboratory- work. An- 

 other glass case at the side of the room to the 

 -west serves the same purpose, while that in 

 the little ante-room contains such special ap- 

 paratus and preparations as are used regularly
