 pt. 1, January 1922, pp. 25-26, 1 fig. 



The sjnnptoms of spirochaetosis in fowls caused by Argas persicus 

 (fowl tick) and the various remedial measures recommended are here 

 described. The following method for preventing the ticks from gaining 

 access to the roosting birds is said to have been in successful use for 

 nearly two years. Four blocks of wood are sunk into the ground and 

 into each of them is inserted a two-foot length of half-inch piping. 

 Narrow cups, with a cap above, to hold kerol or sheep dip, are soldered 

 on to these pipes about 6 in. from the top. The perches are then 

 bolted above these to the tops of the supporting pipes.

The new Tabanids described are Tabanus picticeps, Therioplectes 

 subfasciatus and Chrysops siccus. [According to Major E. E. Austen 

 the first-named is a synonym of T. taeniola, P. de B. — Ed.]

isolated from the Larvae of Lucilia caesar. — U.S. Publ. Health 

 Repis., Washington, B.C., xxxvii, no. 4, 27th January 1922, 

 pp. 164-170. 



An organism, the cultural and morphological characters of which 

 are described, has been isolated from the larvae of Lucilia caesar. 

 The filtrate of the organism is toxic on inoculation and also by the 

 mouth to certain animals, and no protection is afforded by polyvalent 

 botulinus antitoxin in inoculation tests. It varies greatly from the 

 strains of Clostridum botulinum. It has been thought to be the cause 

 of limbemeck in fowls [R.A.E., B, viii, 204], but its relation in this 

 connection cannot yet be definitely stated. Further work is needed 

 along this line, as well as on the relation of the fly, L. caesar, to the 

 disease.
