Texas-fever spleen; and a series of sixteen models of various 
lesions of rinderpest; glanders of horse and man, etc. 
All exhibited a high order of skill, and were interesting and 
instructive. 
Alcoholic specimens of glanders; tuberculosis; swine plague; 
hog cholera ; pleuro-pneumonia bovina ; actinomycosis ; bovine 
broncho- and interlobular pneumonia were shown ; all of which 
were well selected and attracted considerable attention. 
Probably the most instructive and interesting part of this 
exhibit were the photographs and micro-photographs relating 
to infectious diseases and the bacteriological laboratory in 
operation. The photographs were mainly those of contagious 
pleuro-pneumonia of cattle. 
The micro-photographs included some fifteen of Texas fever 
of cattle; other of bacillus tuberculosis, septicaemia, black 
quarter, fowl cholera, swine plague, and hog cholera, portraying 
in an interesting and popular manner the chief factors in the 
causation of some of our most serious animal diseases. 
To these were added an interesting series of similar objects, 
mounted and in sistn under microscopes of appropriate power, 
which with a small bacteriological laboratory, with bacterial 
cultures in active growth, served to attract much attention. 
A considerable collection of dry pathological specimens, 
mainly of the legs and feet of horses, were exhibited, some 
ordinary anatomical diagrams of animals and some very inter¬ 
esting dry mounted specimens of gapes in fowls and glanders in 
horses. 
To these should be added a chart showing the portions of 
the United States in which Texas fever is indigenous, also ex¬ 
hibits of quarantine stations for imported animals, and methods 
of tagging inspected or quarantined animals. 
Altogether the exhibit of this important governmental de¬ 
partment was one calculated to reflect credit upon it and 
certainly attracted greater attention from visitors than any 
other science exhibit presented.
