crows of Senegal, all harboring microfilariae in the blood, with in¬ 
jections of galyl. The microfilariae disappeared from one bird for 9 
days and then reappeared; no adult worms were found postmortem. 
The microfilariae became rare and less active in the second bird; 
2 adult worms were found dead in the abdomen postmortem. No 
microfilariae were found in the third bird for 12 days; 1 worm, 
aparently dead, was found in the abdomen postmortem. Macfie 
(1920) treated 23 patients infested with Guinea worm, Dracunculus 
medinensis, by means of intravenous injections of tartar emetic; the 
worms and embryos died and could either be extracted safely or 
allowed to become absorbed. Jeanselme (1919) Montpelier and 
Ardoin (1919), and Grey (1920) report similar good results in 
infestation with Guinea worm from the use of injections of novar- 
senobenzol. 
The foregoing indicates that as yet we lack adequate evidence 
establishing any drug as effective in the treatment of cases of infesta¬ 
tion with Filaria bancrofti; that we may have a satisfactory treat¬ 
ment for Loa loa, though more work must be done to establish this; 
and that we apparently have satisfactory treatments for Dracunculus 
medinensis. 
In a paper read before the last meeting of the American Veter¬ 
inary ' Medical Association, Hall and Shillinger reported some tests 
of intravenous injections of carbon tetrachlorid and of tartar emetic 
for the destruction of Strongylus vulgaris in aneurisms in horses 
While these tests were inconclusive, the finding of a dead worm in 
an aneurism in one case suggests that further work along this line 
might result in the development of a satisfactory treatment for the 
destruction of these worms. 
We have as yet no well established treatment for lungworms, in 
spite of the many treatments reported in the literature, and at the 
present time nursing treatment, isolation of sick animals, and the pro¬ 
vision of safe and proper food and water supplies are apparently the 
best lines of treatment.
