Discases of the Resprratory Organs. 41 
is with the utmost difficulty it can be checked; more often 
itis the case, of which I have had painful experience, that 
its abatement has not been apomplsned, and death has 
been hastened thereby. 
The remedial measures best adapted to this disease are 
diffusible stimulants and counter irritation.

A teaspoonful every four hours in twice the quantity of lin- 
seed tea for a small dog, and double of each for a large one. 
Counter-irritation may be applied to the chest in the 
form of mustard-plasters, ammonia or terebinth embroca- 
tion, or hot linseed-meal poultices. The temperature of 
the body should be equalised as much as possible, but due 
regard to the observance of proper ventilation is necessary. 
Many persons wrongly imagine that a warm room and the 
exclusion of fresh air is equally necessary to the lower 
animal as to the higher—a fatal error. 
Where the debility rapidly increases, and there is danger 
of effusion taking place, tinct. of ferri, 5 to 10 minims, should 
be added to each dose of the stimulant. This, from its con- 
stringent power, is undoubtedly one of the best agents we 
have for the prevention of dropsies. Where effusion is 
present the ferri iodidum should be substituted, active 
counter-irritation applied to the sides, and a seton may be 
inserted with benefit in front of the chest. It is necessary, 
however, to observe that where, the latter measure is 
adopted, increased support is needful, from the weakening 
tendency of the agent. Where the effusion increases, and 
the case appears hopeless unless the fluid is removed, tap- 
ping the chest by means of the insertion of a small trochar 
between the eighth and ninth ribs may be had recourse to. 
The operation affords immediate relief in removing the 
compression on the lungs and the displacement of the heart. 
It is, however, asa rule, but a temporary respite. Secondary 
secretion follows, and usually more rapidly than that which
