the tapes with dry, powdered arsenic as much as would adhere 
to them, and drew them up into the wound, with the re- 
nr 
suit that we got a most outrageous enlargement of the head 
temporarily. At the end of this time we removed the tapes, 
and washed and dressed the wounds each day till they healed 
up, and then turned the colt out to pasture, when he at once 
began to grow and fill out, and is at the present time in train¬ 
ing and nearly fit to race ; is eating heartily and is doing 
generally well, and I shall be pleased to show him to any one 
who may desire to see him. The enlargement of the head 
still exists, but the breathing is in no way interfered with, and 
when last I saw him two weeks ago, he was as lusty a looking 
youngster as I most ever saw. I may as well say that he 
had been turned out prior to the treatment without any bene¬ 
ficial effect. Taking this in the light of an experiment, which 
does not prove of course the correctness of my theory, as I 
have had no further cases up to the present time to try the 
same course of treatment on, I would ask those who may 
have the opportunity offered them of doing so, to try the 
same course of treatment, or something similar, and report 
the result for the benefit of all.

SANDWORMS AND TUBERCULOSIS. 
By M M. Loetet and Despeignes. 
Sandworms may, for several months, store up in various 
regions of their organisms the baccili of tuberculosis, and 
bring up to the surface of the ground the microbes, thus in¬ 
filtrated in their tissues. 
The authors have demonstrated by inoculation of the 
faecal substances that these lumbricoids deposit upon the 
surface, that they can bring up from deep ground tubercu¬ 
lous baccilli which had been deposited there. Very deep 
flower-pots were filled with earth finely sifted. Tuberculous 
matter was then deeply buried in these pots, and they were 
placed in deep plates filled with water. The surface of the
