of the parasite leads to a tumor presenting a characteristic macroscopic and 

 microscopic appearance. The affection linown as swamp cancer in the Northern 

 Territory of Australia Is almost certainly a variation of the same condition. 



"Prophylaxis should be in the direction of (1) ridding horses of the adult 

 forms of the genus Habronema which are located in the stomach, and (2) in 

 the destruction of feces which bear the embryos and which act as a breeding 

 ground for flies. Complete excision of the lesion before it has become inoper- 

 able is the only treatment to be advised." 



Sclerostome parasites of the horse in England. — II, New species of the 

 genus Cyliclinostomum, C. L. Boulengeb {Parasitology, 9 (1917), No. 2, pp. 

 203-212, figs. 5).— Tliis second part of the paper previously noted (E. S. K., 

 36, p. 280) consists of descriptions of three new species of the genus Cylich- 

 nostomum. 



Parasitic occurrence of Eimeria stiedae in the liver of the dog, A. Guil- 

 LEBEAU (Schweiz. Arch. TUrheilk., 58 (1916), So. 11, pp. 596-602, figs. 6; abs. 

 in Rec. M6d. V4t., 93 (1917), No. 1-2, pp. 71-73; Trap. Vet. BuL, 5 (1917), No. 

 1, pp. 5, 6). — The author describes two cases of the occurrence of E. stieda 

 in the liver of dogs, 10 and 13 years old, respectively, in which great enlarge- 

 ment of the abdominal cavity was the most marked symi)tom during life. 

 Ck)Ccidiosis of the liver, although common in rabbits, Is said to be very rarely 

 found in the pig or dog. 



Chick troubles, W. C. Thompson (New Jersey Stus. Hints to PouUrymen, 5 

 (1917), No. 7, pp. 4). — This circular discusses a few of the more conunon chick 

 troubles, especially tho.se that usually appear when chicks are brooded in large 

 colonies. 



Apparent recovery of a hen infected with bacillary white diarrhea as de- 

 termined by the macroscopic agglutination test, G. D. Horton (Jour. Bad., 

 1 (1916), No. 6, pp. 625, 626). — The author reports upon the recovery of a 

 Bantam hen, indicating the possibility of recovery or tlie throwing off of 

 ovarian Infection. 



The part played by the goblet cells in protozoan infections of the in- 

 testinal tract, P. B. Hadley (Jour. Med. Research, 36 (1917), No. 1, pp. 79-86, 

 pi. 1). — "The present paper presents observations which demonstrate that, in 

 the case of tlie flagellate protozoan. Trichomonas, tJie cause of an acute malady 

 of several species of birds, notably the turkey (blackhead), the avenue of 

 invasion of the subepithelial tissues Is the goblet or chalice (gland) cells located 

 In the fundus of the crypts of Lieberklilin. It is suggested that the passage 

 of the parasites through these cells Is not inadvertent, but due to a natural 

 invasive power present in the motile flagellate trophozoite which accomplishes 

 the Infection of the deeper tissues." 



Eimeria avium: A morphological study, P. B. Hadley and ELiZAnETii E. 

 Amison (Arch. Protixtrnk., 23 (1911), No. 1-2, pp. 7-50, pis. 2).— Following an 

 Introduction and historical r^sum6 the authors dlscu-ss the material, methods, 

 and technique and the life cycle of the coccidium and the infectious process ; 

 and give a detailed description of the several stages of the coccidium, namely, 

 the mature cyst, sporoblast.s, .sporozoites, sch!zout.s, nierozoltt'.-^, macrogamotos, 

 microgametocytes, and microgametes. 



A list of 37 references to the literature is included. 



Coccidia in subepithelial infections of the intestines of birds, P. B. Haw 

 LEY (Jour. Bad., 2 (1917), No. 1, pp. 75-78).— This is a brief report of studies. 

 of coccidia now in progress. In continuation of investigations above noted, in 

 which the author considers In a preliminary way the bearing of certain of the 

 observations upon the problem as discussed by Smiti* /^^ S. R., 35, p. 684).
