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 V2 oz. each of Thymol, i^ oz. in all being suffi- 

 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 5 

 species of Sclerostomes — robiistion, eqiiinuni and tetracantJiuni, 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 ofif one by one in quick succession. This 

 disease, also common in United States, is caused by a nematode 

 worm, CEsophagosioma cohimbiamim 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.
