THE INFLUENCE OF IODINE. 
the strength of the balls to ten grains per day. Seeing no bene¬ 
ficial effect from this plan, I applied the iodine in the form of a 
liniment to the tumours, made according to the following formu¬ 
la:— . *N| m -?<•£;

After a fortnight’s trial they were discontinued, and the animal 
was turned to grass. No medicines were given for some time ; 
the glands remained as hard and as large as when I first ex¬ 
amined them. 
Determined not to be baffled, I tried the effect of the iodine 
in the form of the hydriodate, as an ointment and internal 
medicine. 
They were employed according to the following formulae:—

The ointment was applied twice a-day, and two of the balls 
were given daily,—one in the morning, and the other in the 
evening, increasing their strength two grains per day, until 12 
grains were administered twice a-day. 
In about a fortnight a considerable alteration had taken place 
in the enlarged glands: they first became softer, and afterwards 
began to diminish in size. The internal use of this mineral was 
now discontinued, but the unguent was applied for about ten 
days longer, at the end of which period the glands were reduced 
to their natural size. 
In reviewing the history of this case, it appears that the blis¬ 
ters applied by the farrier, and the seton and mercurial frictions 
by myself, instead of diminishing, increased the disease. Neither 
did the iodine, when employed in its metallic state, appear to 
have any effect whatever on the enlarged glands. The influence 
of the salt was perceptible after being used for a few days. I am 
not prepared to say, that the reduction was altogether owing to 
the hydriodate, and none to the metal. The efficacy of the salt, 
however, in this case, was very perceptible; and it is plain that 
it must act with considerable energy upon the whole system ; 
for to suppose that it travels to the diseased gland, and expends 
its influence there, and there only, would be absurd.
