vitriol are favourite treatment among" the natives, but reprehen- 

 sible because they simply dry up the surface and produce a false 

 appearance of healing. This surface healing is specially to be 

 avoided, all dead tissue must be carefully removed, depending 

 orifices for escape of pus made, the ulcerated surfaces aroused 

 to activity in various ways as by scraping or dissecting- off their 

 surfaces, application of the hot iron, or other stimulant. Tonics 

 will be found beneficial in promoting the healing process. 

 The notes from the Nile Expedition Report concerning saddles 

 for camels are of considerable practical value. 



The Hump is specially tedious in healing; it is also liable to 

 slough and to become the seat of fistula. This part of the body is 

 mainly composed of fat in the meshes of fibrous tissue and care- 

 ful examination has shown that it contains some muscular 

 structure. Its firmness is considered a guide to condition of the 

 animal and a large full hump is a good point in a dromedary. 

 The camel man before an expedition feels the hump critically to 

 determine whether his animal is "fit" and aims at keeping the 

 hump in good order. This part must be carefully examined in 

 purchase of camels both as an index of fitness for work and 

 also because it is liable to hump gall from the saddle, and as 

 Vallon discovered, even when there is no outward sign of dis- 

 ease, cancerous disorder may be going on centrally in the part. 

 Vallon describes this state as true encephaloid, but there is reason 

 to believe from experience in India that such a state is very rare 

 and that the apparently cancerous ulceration is generally only 

 ordinary traumatic lesion aggravated by neglect or maltreatment. 

 An interesting observation by Lombardini is that even in the 

 droinedary there is a rudiment of the second hump, the two fatty 

 masses being separated by a well-marked septum. A diagram 

 published by the latter observer well illustrates this point and 

 also the relations which the humps bear to the spines of the 

 dorsal and lumbar bones. A glance at the skeleton of the camel 



to cool until partly solidified, and then applied with a paint brush was found 

 good for galls. Applied night and morning it served well to keep off flies 

 (Byrne). Martin found a mixture of salt, flour, and burnt felt a useful 

 application.
