THOMPSON YATES AND JOHNSTON LABORATORIES REPORT 
Laboratories of Tropical Medicine 
These are situated on the first floor of the Johnston Laboratories, and are 
contained within a large room, about 95 feet long and 35 feet broad. The main part 
of the room is devoted to students, but three chambers are partitioned off for the 
special use of persons who wish to do research work in connexion with Tropical 
Medicine and Parasitology, each of these rooms having all fittings and appliances for 
this purpose. One end of the floor contains the professor's room and the incubator 
room. The whole is walled with white glazed tiles. The floor is rendered imper- 
meable by a layer of deep red lito-silo. Along the walls of the whole floor there runs 
a bench for microscope work, covered with a thick layer of sea-blue lito-silo. Electric 
light, gas, and water are suitably fitted at distances of every four yards of this bench 
for the use of students. The partitions of the room are fitted with cupboards, in 
which the museum of tropical diseases, which the school is now purchasing, is being 
arranged. Steam is also laid on to the laboratory, which possesses all the necessary 
apparatus. There is accommodation for quite forty workers in the new laboratory of 
the school. 
Laboratories of Comparative Pathology 
The Institute of Comparative Pathology occupies the basement of the new 
Johnston Laboratory, and comprises the lecturer's private laboratory, a general 
laboratory, incubating room, sterilizing room, and a post-mortem room. 
The laboratories are fitted with window benches and tables, and have a 
complete outfit of gas, water, and electrical fittings ; the walls are tiled with white 
glazed tiles, and the floors and bench tops are covered with lito-silo. Each side of 
the partitions dividing the area into sections is fitted with cupboards, which will be 
largely utilized for museum purposes. The post-mortem room will be fitted with 
a post-mortem table for large animals. 
These laboratories will be furnished for lectures, demonstrations, and practical 
work in the subjects of comparative pathology and bacteriology, and also for the 
testing of various vaccines and sera prepared at the Institute's Farm Station. Facilities 
will also be afforded for acquiring the technique necessary for the manufacture of 
these products, and also for research work. Practical instruction in the physiological 
and pathological actions of these and allied substances will also be provided. 
The farm in connection with the Institute is favourably situated in a most 
suitable and accessible agricultural district in North Cheshire. It has been provided 
with laboratories, fitted up with modern scientific appliances and apparatus for the 
production on a large scale of vaccines and sera. A general bacteriological 
laboratory, an incubating room, mixing, distributing, and sterilizing rooms, and a 
separate room specially set apart for the preparation of calf-lymph vaccine, and 
another room for plague prophylactic and serum, make up the laboratory accommo- 
dation.
