COM PTE RENDU OF THE 
This last mode has not hitherto received confirmation by ex- 
perimentation. 
III. Transmission to man is possible in the same ways, by con- 
tact, and also, as it is said, by cohabitation. 
IV. The most certain mode of communicating glanders is by in- 
oculation under the epidermis. 
V. It is likewise with certainty communicable from the horse to 
other solipedes. It is in this way that man commonly contracts the 
disease ; and if it be communicable to the sheep and dog, as some 
rare experience would lead us to imagine, it is by this mode only that 
such transmission is practicable. 
VI. Its seat is throughout the orgasm infected by the virus ; and 
all tissues the products of it, impregnated with blood, possess — it 
is true, in different degrees — the property of transmitting the 
disease. 
VII. Nevertheless, there are situations in the body where the 
infection of glanders becomes developed and communicable more 
apparently than in other parts : the respiratory apparatus, and 
especially the na^al cavities, and the whole of the external tegu- 
mentary system, with the cellular tissue, and the superficial lymph- 
atic system. 
VIII. The frequency of the appearance of symptoms denotive 
of the glanderous infection in these places of predilection, has long 
caused glanders to be considered as a disease of the lymphatics, of 
the nose, the skin, and subcutaneous cellular membrane : an error 
which observation has corrected. 
IX. Glanders is a disease of the system at large, exhibiting an 
especial predilection for certain organs, a character common to it 
and all virulent diseases, be what will their nature. 
X. Among the numerous causes to which the origin of glanders 
is traced, the most certain, in our opinion the most infallible in its 
results, is work, over- work, the limitless unmeasured work to which 
are condemned those unfortunate horses which are used in carrying 
on industrial labours either on a large or a small scale. 
Some modern chemists have given it as their opinion that 
animals, man included, were nothing, in a scientific point of view, 
more than sorts of furnaces or machines for carrying on combustion. 
This ingenious supposition is realised to the letter by those who, for 
the most part, use the horse in their employ. In their hands the 
animal is no more than a machine, from which they expect an in- 
cessant movement in direct and absolute ratio to the quantity of 
aliment furnished for its consumption. Nutriment and labour con- 
stitute for them the simple calculation of usefulness of th£ animated 
moving power.
