During the early part of 1916 there was a heavy mortahty among 

 pack-animals, mules and donkeys, accompanymg the Belgian troops 

 encamped north of Lake Kivu. These animals came mostly from the 

 Egyptian Sudan, travelling by way of Uganda. Examination of 

 their blood showed that death was due to an infection caused by a 

 dimorphous trypanosome of the type, Trypanosoma pecaudi. This 

 parasite was proved to be virulent to the grey rat of the country, to 

 dogs and to a burrowing rodent, Tachyorectes annectens, which was 

 abundant in the upland prairies near the lake.

Two cases are recorded of immunity in camels to Trypanosoma 

 berberum. The experiments are given in detail and showed, in the 

 first case, an acquired immunity following an infection inoculated in 

 the laboratory, later inoculations being given to maintain and streng- 

 then the immunity, and in the second case a natural immunity. 

 In both cases the animals became infected but showed no sign of 

 illness, having therefore what is termed relative immunity. It is 

 considered that this relative immunity may be due to the persistence 

 of a slight mfection ; but this infection must have been very slight, 

 since inoculation into dogs of large quantities of blood from the 

 animal produced no infection. Such animals, however, constitute 

 persistent reservoirs of the \irus, although, trypanosomes being very 

 rare in the blood, flies do not readily become infected in biting them.

Mange is the disease second in importance among camels of northern 

 Africa, debab being the worst. The Sarcoptid mite producing the 

 disease, Sarcoptes scabiei var. cameli, is described. An account is 

 given of the course of the disease among a troop of fifteen individuals 

 which were sent to the Algerian coast in the spring. They were 

 in a poor state of health, and most of them showed some traces of 

 mange. Although the animals were not worked and were well fed, 

 after some weeks in which the disease remained in abeyance mange 

 suddenly attacked the whole body of all the animals, causing death 

 in two or three months. The treatment with washes that has been 

 given to horses with much success proved very harmful to camels, 

 which are extremely sensitive to moisture. The best treatment as 

 yet known is the application of the preparation of tar made by the 

 natives with Juniper us phoenicea and Thuja articulata ; this, applied 

 promptly, thoroughly and repeatedly, has given much success.
