and sub-coccygeal regions are covered with a layer of hard, dry, 

 brittle cakes of a lightish brown color, easily detached by fric- 

 tion;" elsewhere the sides, flanks, neck, and tail are said to be 

 specially affected, but it is evident that in severe cases the seat 

 of eruption is no guide in distinguishing between the contagious 

 and non-contagious enzootic skin-disease. Burt describes the 

 disorder as follows " The indications of the disease in the early 

 stage resemble those of eczema, and in the latter those described 

 as ichthyosis. Symptoms : in the early stage the first symptoms 

 observed were small bare patches about the size of a pea, with 

 altered condition of the cuticle, consequent on eczematous erup- 

 tion. This eruption was noticed in all parts of the body except- 

 ing the top of the neck and back, where the hair is thickest. 

 This did not appear to be accompanied by any marked irritation. 

 It was followed by an apparently thickened state of the skin 

 and increased irritation, and the patches running together ; the 

 parts now most affected were between the fore limbs, under the 

 chest, the flanks and inside the thighs, where the skin is thinnest 

 and least covered with hair. It was also observed that the 

 muzzle and the parts just above the foot-pads became affected. 

 There was a peculiar papillated appearance of the skin immedi- 

 ately above the feet. Later on, the skin assumes a very thick- 

 ened and corrugated appearance, more especially between the 

 fore legs, flanks, and inner side of thighs. About this stage, 

 the camel, if previously in condition, begins to fall away ; even- 

 tually the lymphatics of the part become involved, being noticed 

 to be enlarged, and oedema of the extremities follows, accom- 

 panied by great loss of condition and general febrile symptoms 

 rendering the animal quite unfit for work. At the same time 

 the top of the neck and back remained perfectly free, the 

 rest of the body being denuded of hair. At this stage, also, 

 many camels thus affected would be seen standing in the 

 lines perfectly quiet, apparently showing no symptoms of irri- 

 tation. It was also observed towards the close of the Expe- 

 dition, that several camels, the private property of Officers, 

 havino- received better treatment, as regards feeding and work, 

 than other camels, were no worse than when first seen at the
