DISEASES OF THE RESPIRATORY ORGANS.

the surface was frequently applied a powder consisting of 
Lapis Caliminaris, Resina Flav. et Bol Armen., until the 
synovia became thickened and less profuse. I then substi¬ 
tuted Sol. Zinci Fort, for the Tine. Ferri Mur.; and I am 
happy to say my efforts were at last crowned with suc¬ 
cess. The horse is now removed from the slings, the 
escape of synovia has ceased, and he can not only bear his 
whole weight upon the injured leg, but walks very little lame. 
I have no doubt, after the application of an iodine blister, the 
usefulness of the animal will be unimpaired. 
ON SOME OF THE DISEASES OF THE RESPI¬ 
RATORY ORGANS OF THE HORSE AND 
OTHER ANIMALS.

[Continuedfrom p. 216.) 
THE VARIOUS NOISES PRODUCED DURING RESPIRATION 
UNDER DIFFERENT CIRCUMSTANCES. 
No attempt has ever been made to convey by words an 
idea of the sounds naturally resulting from the inhalation 
and exhalation of the air while the respiratory organs are in 
a healthy condition. That a certain sound accompanies the 
act, and that during respiration under exertion that sound 
amounts to a very decided noise, is a fact perfectly familiar 
to every one, but the absence of any artificial sound of a like 
character with which to compare it, renders it impossible to 
employ a term which would indicate it with any approach 
to exactness. 
Alterations in the character of the respiratory sounds 
resulting from disease are no sooner apparent, than we are 
at once in a position to designate the tone produced in a 
manner calculated to convey to the mind a very positive idea 
of its nature; thus, “grunting,” “whistling,” and “roaring,” 
three most common expressions among horsemen, are so 
absolutely descriptive of actual sounds, that any one would 
comprehend their force, without knowing or thinking any¬ 
thing of their application. 
Other expressions of a less definite signification are used 
to indicate peculiar modifications of sound—as high-blowing, 
piping, and fluttering. None of the terms are remarkable
