fitted up for special experiments and investigations. On the same 

 floor there are two quarantine rooms, one of which is here shown in 

 Fig-. 3, wherein aie seen the cages in which are kept the animals under 

 observation, or those presenting pathological conditions requiring their 

 isolation. Beyond these we have the autopsy room, fitted out with all 

 the modern appliances for performing post mortems. 



In the case of three of these rooms, the walls are coated with hard 

 paint, and center-drains are found in their concrete floors for the pur- 

 pose of frequent flushing. One of the quarantine cages measures 27 X 

 24 X 20 inches and a larger one 29 X 36 X 30 inches, the top in any 

 case being five feet from the floor. These comfortable quarters are 

 of galvanized iron and fitted with a door which can not be opened by 

 the animal. 



Passing to the second floor of this building, we find it given over to 

 a single room of considerable size, measuring thirty feet by sixty-nine. 

 It is lighted overhead by a large, central skylight, while windows are 

 only found in the north and east walls, the south and west ones being 

 unpierced in any way to admit light. In this room is kept the collec- 

 tion of pathological specimens, some of which are from human subjects 

 for the purposes of comparison. Many drawings, charts and photo- 

 graphs are upon the walls, while tables and desks are placed in con- 

 venient corners for the use of those doing clerical or laboratory desk 

 work.
