CAUSE OF GLANDERS. 
199 
Atmospheric Influence .—This has much to do with the pre¬ 
valence of glanders. It is not so frequent in summer as in 
winter. There is perhaps a reason for this, independent of at¬ 
mospheric influence; the animal is not exposed to the same ex¬ 
citing causes from our absurd treatment. The stable is not so 
close nor so foul, and the alternation of temperature is not so 
violent. 
Moisture in various Forms .—It is not so prevalent in a dry 
winter as in a moist one. Moisture has much to do with the 
existence and the spread of almost every epidemic or contagious 
disease. It is necessary to the decomposition of every animal 
and vegetable substance, and it seems necessary likewise to give 
deleterious influence to the gases extricated in that decom¬ 
position. 
There are several remarkable cases of the connexion of mois¬ 
ture, or moist exhalations, with the prevalence of glanders. 
W hen new stabling w r as built for the troops at Hythe, and in¬ 
habited before the walls were perfectly dry, many of the horses 
that had been removed from an open, dry, and healthy situation, 
became affected with glanders. Some time having passed 
over, the horses in these stables were as healthy as the others, 
and glanders ceased to appear. 
An innkeeper at Wakefield built some extensive stabling for 
his horses; and, inhabiting them too soon, he lost a great pro¬ 
portion of his cattle from glanders. There are not now more 
healthy stables in the place. The immense range of stables under 
the Adelphi in the Strand, where light never enters, and the 
supply of fresh air is not too abundant, were for a long while 
notoriously unhealthy, and many valuable horses were destroyed 
by glanders; but now they are filled with the finest waggon 
horses that the metropolis or the country contains, and they are 
fully as healthy as the majority of stables. In a French journal 
an account is given of one of the French cavalry regiments. It 
w 7 as in a low damp situation, and the stables were damp; and 
they lost in that year thirty-one horses from glanders. Their 
quarters were then shifted to a drier situation and better con¬ 
structed stables, and one only was destroyed in that year. 
The Influence of Age. —Age seems likewise materially to in¬ 
fluence the development of glanders. Except in cases where 
the foal has sucked a glandered mare, there appears to be an 
almost perfect immunity until the animal is three years old. It 
is true that the horse can scarcely be said to be exposed to the 
usual exciting causes of this disease, until he has arrived at that 
age; and he is comparatively exempt from the influence of con¬ 
taminated air, or sudden alternations of temperature. From that
