Inflammation of the Respiratory Mucous Mem- 
brane. — Among the diseases that we attribute to atmospheric 
influence, and which have been frequent during the past year, 
are angina, bronchitis, pneumonia, pleurisy, and mucous and 
bilious fever. All these maladies are to be attributed to suspend- 
ed or suppressed perspiration ; and although common at all 
times, are much more prevalent when the air is agitated by fre- 
quent storms. 
The horses that live in places where the air is little disturbed, 
and seldom or never go out of them, as in the coal mines, are 
scarcely influenced by the changes of the atmosphere. It is a 
common remark, that in these subterranean abodes, the old 
maladies of the chest with which these animals were affected 
before they descended, not only do not advance, but in a manner 
disappear, if the labour to which they are subjected is not dis- 
proportioned to their strength. Very often we find that glan- 
ders disappears there without any medical treatment. 
Angina. — The diseases which pass under this name, have 
principally affected the larynx, and have been attended by great 
difficulty of breathing. A bleeding practised during the acute 
stage, and warm emollient drinks, have usually removed the com- 
plaint. Sometimes mustard to the fore-arm and to the thighs, 
setons in the chest, and embrocations of olive oil and oil of 
morphine under the throat, have been added, and the throat has 
been covered with sheep-skin. 
In three of these cases the inflammation extended to the upper 
part of the trachea, and was accompanied by a sonorous respira- 
tion similar to roaring. 
The preceding treatment not being effectual, more copious and 
frequent bleedings from the jugular w'ere effected, and a large blister 
was applied to the throat. The difficulty of respiration still increas- 
ing, it was necessary to open the trachea in order to enable the 
animal to breathe through the orifice, and at the same time to 
place the larynx in a complete state of inaction. Even these 
means were inefficacious, and in about six weeks, tw r o of the 
horses exhibiting evident symptoms of glanders, and the third, 
although he still continued to feed, yet being reduced to a skele- 
ton, they were destroyed. The mucous membrane of the larynx 
was thickened in all these animals, and ulcerated in one of them. 
One of those which had shewn symptoms of glanders had 
agglomerated tubercles, of the size of a small nut, in the inter- 
stices of the muscles that occupied the space between the right 
branch of the thyroid and the cricoid cartilage. Another had 
the cricoid cartilage ossified, and also the right branch of the 
arythenoid towards its insertion into the thyroid. The third had
