temperature within the chamber rising to 86° F. Fumigation lasts 

 two hours. On the horse leaving the chamber its head and neck 

 are subjected to a vigorous dressing with cresylated oil, 1 in 10. In 

 order to destroy mites in the external ear a freshly made, warm 

 emulsion of 3 per cent, cresyl is introduced into the ear, and also 

 rubbed into its base. Three days after fumigation the animal is 

 again washed. This treatment has proved to be effective, simple, 

 inoffensive, rapid and economical. Ringworm also yields to this 

 treatment, while lice and their eggs are completely destroyed in 25 

 minutes,

In view of the success attending the treatment of mange in man 

 and horses in the British army by fumigation with Clayton gas the 

 French authorities examined this method in 1917. The procedure 

 adopted has been described in the preceding paper. At a strength of 

 3-4 volumes per cent, of sulphurous anhydride from 1 to 2 hours were 

 required for fumigation. Beginning on the third day afterwards, 

 the animals were well rubbed down daily. No other treatment was 

 required, and every one of the 70 horses dealt with was cured. Harness 

 may be disinfected at the same time, and the gas will also cure ringworm 

 and destroy lice.

This report relates to work in connection with the outbreak of 

 plague in Malta in the spring of 1917. From 2nd April to 1st July 

 about 1,000 rats were examined, 15 of which were infected with 

 Bacillus pestis. Xenopsylla cheopis, Ctenopsylla musculi, rarely 

 Ceratophyllus fasciatus, and still more rarely Ctenocephalus sp., were 

 found on the rats, but never on man. Pulex irritans was found 

 exclusively on man. From Mus rattus in the plague-infected area 

 102 fleas were examined, of which 60 were X. cheopis, 38 Ctenopsylla 

 musculi, 3 Ceratophyllus fasciatus and 1 Ctenocephalus. From Mus 

 decumanus from the non-infected area of 180 fleas examined, 118 

 were X. cheopis, 49 C. musculi, 3 C. fasciatus and 10 Ctenocephalus. 

 A species of tick {Ixodes) was found in great numbers on sopie indivi- 

 duals of M." rattus and M. decumanus and a louse was also noted on 

 both species of rats,
