about six inches in length across the inner side of the fore-ai m, 
just above the lower termination of the superficial pectoral i ; 
muscle. It was washed with a disinfecting solution, sutured, t 
and bandaged. Being in a difficult place to dress properly, 
suppuration occurred and only a small portion healed by pri¬ 
mary union. After the sutures gave way bandages were dis¬ 
continued and only the powder applied, as in other cases. 
The wound healed fast. 
A good way to apply the powder is by means of the small 
insect-powder blower, which can be obtained of any druggist, i 
In the absence of this or any other powder blower,- I apply 
it with a spatula, or small wooden paddle. In some cases 
this is preferable to the blower, as more can be made to adhere. | 
The experiments and results obtained therefrom, referred 
to in the beginning of this article, were as follows: Knowing 
that iodoform was extensively used as an application to wounds, 
but still claimed by some to be of little value, we determined 
to test its effects on the staphylococcus pyogenes aureus, one 
of the most common pus microbes. In order to have the cir¬ 
cumstances as similar as possible to those in wounds treated | 
with iodoform, surface inoculations were made on agar-agar,j 
and iodoform dusted over the surface. The cultures were:! 
then either left to develop in the temperature of the room or 
placed in a thermostat at a temperature of about 37 0 Centi¬ 
grade. No growth was perceptible in any tube treated in 
this way, even when left in the thermostat for several days, but 
in every instance the control tube (inoculated tube not dusted! 
with iodoform) showed, after twenty-four hours, a vigorous 
growth of the aureus. 
The same experiment was repeated, with the exception ol 
using bituminized iodoform in place of the simple iodoform 
with the same results. No growth whatever took place cxj 
cept in the control tube, where it was vigorous. 
The new preparation known as iodol, which is claimed ten 
be equally as effective as iodoform, but minus the disagreeable, 
odor, was also tried, but with very different results. In every 
instance there was a very vigorous growth, apparently as vig 
orous as in the control tubes.
