with the various files on either side, the reading room is in the 

 alcove, and the book stacks are arranged on either side in the wings 

 of the room and in the stack rooms. They are metal and of the 

 type supplied by the Library Supply Company of Boston. 1 



The serum laboratory in the power house has the same general 

 arrangement of desks and hoods as the biological portion of 

 the building. It needs no special description, with the exception 

 of the serum kitchen, which contains a large, steam-supplied auto- 

 clave and sterilizer of the pattern made by Messrs. Bausch & Lornb, 

 and a centrifugal from Lautenschlager, of Berlin, the latter driven 

 by a four-horsepower motor. The serum laboratory also is pro- 

 vided with two large incubators of the same type as those used 

 in the biological division. The vaccine stable is placed immediately 

 next to the power house. It is fly-proof throughout, with cement 

 floors and stalls for twenty calves and an operating room for inocula- 

 tion and for collecting the virus. The calves in this place can be 

 kept under thoroughly aseptic conditions. On the other side of 

 the power house is located the building for small animals. The 

 guinea pigs and rabbits will be kept in galvanized-iron cages placed 

 on racks well in the center of the room to insure coolness. To 

 the rear of the driveway is a jiorse stable of a capacity sufficient 

 to accommodate twelve horses, fly-proof, as in the case of the 

 building for vaccine calves. It contains an operating room which 

 will make it possible to collect serums according to the most 

 improved methods. The last building of all is a small, two-storied 

 one for dogs, goats, and monkeys. 



APPARATUS AND SUPPLIES. 



In Manila the greatest difficulty encountered by a laboratory is 

 to keep on hand a sufficiency of special supplies, and also to 

 provide the apparatus which may be necessary. While the equip- 

 ment may apparently be complete, nevertheless requests for new 

 classes of work may suddenly bring the laboratories face to face 

 with the necessity of purchasing new kinds of apparatus, and until 

 these are delivered of refusing to do the work demanded. To procure 

 stores from Europe or America takes at least seven months. As a 

 result the equipment of a laboratory at such a distance from the 

 base of supplies must be somewhat more extensive and complete
