form gain access to the intestines of herbivorous animals, being 
swallowed with the green plants on which they feed. The embryos 
develop rapidly and finally encyst themselves in the walls of the 
stomach, coecum and colon, and later on emerge as full grown Scler- 
ostoma. Dochmius duodenalis, which is very similar to the Scler- 
ostomes, causes the dreadful disease in man known as ‘“‘ Kala- 
azar’’ or “ Beri-Beri.” The best remedy to be administered are 
‘repeated doses of % oz. each of Thymol, 1% oz. in all being suff- | 
cient to expel all the free worms, the treatment to be repeated when 
the cysts have developed. 
In a subsequent paper in the same part Mr. Giles describes 3 
species of Sclerostomes—vrobustum, equinum and tetracanthum, all 
infesting the horse. 
Following this paper is. one by the same author ‘‘On Nodular 
‘Disease of the Intestines in Sheep.’’ In Assam and Burma the 
keeping of sheep is almost impossible on account of this nodular 
disease, the sheep dying off one by one in quick succession. This 
disease, also common in United States, is caused by a nematode 
worm, Qsophagostoma columbianum Curtice. The ova are carried 
away by the dung, hatch out in one or two days and become Rhab- 
dites with short tails. They moult at least three times, and feed on 
green vegetation. Their eggs pass into the intestines of sheep, 
encyst there and later develop into CEsophagostomas. No success- 
ful treatment is possible and no prevention is likely to succeed. The 
Rhabdite forms exist continuously as free nemadotes and only await 
the opportunity to pass into the sheep. Stall feeding with steamed 
fodder appears to be the only prevention. G.E.
