728 EXPERIMENT STATION RECORD. 



Ahl., Orig., S5 {190S), No. 1, pp. 37-42). — The author investigated an outbreak of 

 disease among t-hirkens in Turin. The combs, lungs, liver, spleen, and kidneys 

 aiipeared i)erfeotly normal while the alimentary tract was affected in various ways, 

 accnnling to tiie duration of the disease. A microscopic and bacteriological investi- 

 gation failed to reveal the i>resence of any micro-organism, but the author believes 

 that the disease is due to an organism sufficiently small to pass through a porcelain 

 (liter. Inoculation experiments with animals showed tliat the virus was pathogenic 

 for chickens but not for ral)l)its. 



Parasitological notes, B. G.\lli-Valekio {Centbl. Bali. ii. Par., J. Abf., Orig., 35 

 {1903), No. 1, pp. Sl-91, figs. 4). — Brief notes on various plant and animal parasites,

 Fle'mh- n. Mlklihyg., 13(1903), Xo. 5, pp. 136-139) .—Tha examination of beef during 

 the ordinary meat inspection in the slaughterhouse at Trieste yielded valuable data 

 on tlie occurrence of the beef measle worm and its relative distribution in various 

 muscles. This parasite is found most extensively in the internal and extei-nal 

 muscles of mastication. 



Trichinosis and heredity, A. O. de Landazuri {Gac. Med. Zool., 27 {1903), 

 No. 16, pp. 261-364). — Attention is called to the possibility of intrauterine infestation 

 by trichina in hogs, and a few (lases are cited in which such a method of infesta- 

 tion appeared to be demonstrated. In such cases it was urged that the public should 

 be warned against the use of the meat of young pigs.
