One of the conclusions reached is that typhus cases may prove 

 infective to lice as much as 3 weeks after the end of the fever. After 

 a period of 6 weeks this does not seem to be the case. The incubation 

 period for typhus was found to be 14 days.

Sarcoptic mange is particularly serious in the case of camels and 

 dromedaries, and in some caravans all the animals may be afTected 

 nnd reduced to a serious condition of wasting. The Moors resort 

 to applications of tar after pulling out the hairs ; fermented camel 

 urine, which is strong in ammonia, is also used for softening the crusts. 

 The lack of prophylaxis accounts for the rapid spread of the disease. 

 Good results were obtained with a grease ointment containing sulphur 

 and cresyl, but the grease impedes clipping and turns rancid owing to the 

 heat and may cause vesication. A soap omtment has given very excellent 

 results. This may be prepared by soaking white soap shavings 1| lb. 

 in tepid water 1 qt. After 24 hours flowers of sulphur \ lb. and then 

 cresyl | lb. and petroleum 6 oz. are added. After clipping, the paste 

 is applied with a brush or by hand and well worked in with the 

 iinger tips. On the following day some of the paste will be found on 

 the hair and should be rubbed back on to the skin. After an interval 

 of 4 days the parts are cleansed with a brush and tepid water. In 

 conjunction with segregation this treatment has given excellent 

 results. Of 100 camels so treated there were only about 10 cases 

 of re- infestation.
