proposal was discussed at the meeting and a resolution was passed in 

 favour of the creation of a separate organisation for the study of the 

 insect parasites of man and animals in connection with the Civil 

 Veterinary Department on the lines suggested.

The rural population of Millard County, Utah, has in recent years 

 been troubled by a disease caused by the bite of a fly on some exposed 

 part of the body, and giving rise to a septic fever lasting from 3 to 6 

 weeks. The first case known to have terminated fatally was reported 

 in 1919. Guinea-pigs and rabbits have been inoculated from a typical 

 case of the fever and both developed the disease, which terminated 

 fatally after a few days. Cultures made upon coagulated egg-yolk 

 Aaelded a growth of small non- motile coccobacilli which reproduced the 

 lesions of the disease in guinea-pigs. This is believed to be identical 

 with Bacterium tularense obtained in 1911 in a similar manner from 

 ground squirrels in California that were suffering from a new plague- 

 like disease.

The War has been responsible for a great increase of mange among 

 horses, an inevitable consequence of the crowding together of all 

 grades of horses, frequently in quarters that there was no opportunity 

 to disinfect after the evacuation of the previous occupants, sometimes 

 under conditions of insufficient nourishment and poor shelter. The 

 nature of the malady in its three forms, sarcoptic, psoroptic and 

 symbiotic mange is discussed, and the role played by Acarid parasites 

 explained. Sununer is the most favourable time for treatment of the 

 disease, the cure requiring from two or three weeks to two months 

 or more. Horses affected with mange should be rigorously isolated 

 from healthy ones, and should not be considered cured until every sign 

 of ill-health has disappeared and everything about them, stables, 

 harness, etc. has been throughly disinfected with cresyl solutions and 

 milk of lime wash. Army treatments comprised sulphur or arsenical 

 baths or fumigation with sulphuric anhydride. The latter method, 

 though excellent, is obviously impracticable on ordinary farms. Many 

 forms of sulphur treatment may be substituted, sulphurated oil 

 probably being the most convenient and rapid in action. Attention 

 is again drawn to the fact that horse mange has been included in the 

 list of notifiable diseases [see this Review, Ser. B, v, p. 120].

The author records an observation confirming the fact that wild 

 animals are the reservoirs of trypanosomiasis from which Glossina 

 become infected, and proving that trypanosomes taken direct from
