From observations on sheep the author beUeves that mange cannot 

 become estabUshed unless the skin is in a receptive condition, predis- 

 posed by a skin catarrh. Mites often occur in the sebaceous glands of 

 man and in the eyehds of sheep, cattle, and pigs without a general 

 infestation. The host tissues attempt to combat mange by an inflam- 

 mation, and this should be assisted by increasing the counter irritation. 

 Sulfargil is recommended as suitable for this purpose, and the author's 

 method of using this preparation is described.

 Qu^ities of the Granary Weevil, Calendra granaria. — Amer. Jl. 

 Trop. Med., Baltimore, ii, no. 3, May 1922, pp. 199-211. 



In view of the widespread behef that the granary weevil, Calandra 

 (Calendra) granaria, can be used as an efficient substitute for the 

 ordinary blister beetle, Lytta [Cantharis) vesicatoria, and also owing 

 to many current opinions concerning the poisonous nature of this 

 weevil, the literature concerning the insect from these aspects is reviewed, 

 and many experiments to test their truth are described. From the 

 results it may be concluded that the granary weevil contains no 

 cantharidin and cannot be used as a substitute for the blister beetle, 

 nor is there any evidence to indicate that it is responsible for cases of 

 poisonous flour.

Panama. — Amer. Jl. Trap. Med., Baltimore, ii, no. 3, May 1922, 

 pp. 251-266. 



Since the publication of a recent article demonstrating that Ornitho- 

 dorus talaje is the transmitting agent of relapsing fever in Panama 

 [R.A.E., B, ix, 198], the authors have been conducting investigations 

 with a view to determining the identity of the spirochaete that is the 

 cause of the fever. By means of comparative studies it is found that 

 the spirochaete concerned is distinct from Spirochaeta obermeieri, 

 S. novyi, S. kochi, S. duttoni or 5. carteri.

The main points of a study of an occurrence of plague from July to 

 September 1921 in the province of Naples are discussed. The disease 

 was imported by rats on board plague-free steamers arriving from 

 infected ports, and in spite of the most rigorous measures directed 

 towards preventing the landing of rats. Most of the rats normally
