cariasis. This affection has been seen in two goats from the 

 Western Pyrenees (Pesgs and Morot). There appeared to be no 

 local irritation, but examination of the cerumen revealed the 

 presence of the acarus which has almost the same size and form 

 as those of the larger animals. It has been suggested that inves- 

 tigation may reveal their presence in many goats. If found to 

 cause irritation injection of glycerine, with or without tobacco 

 should destroy them. 



Symbiotic Scabies (Acariasis) in Goats. This has been 

 described in Angora goats and differs from the symbiotic acariasis 

 of horse, ox and sheep, in that it does not show the same prefer- 

 ence for the lower parts of the limbs. In one outbreak described 

 by Mollereau the disease was, however, confined to one hind pas- 

 tern which was encrusted with scabs and shreds of straw, and 

 attended by extensive exudation or oedema, and even commencing 

 gangrene. The symbiotes .swarmed beneath the scabs. In 

 Delafond's cases it attacked the back of the ears, sides of the 

 neck, shoulders, back and loins, and the root of the tail, and 

 generally avoided the lower parts of the trunk. There is at first 

 redness with papular eruption and exudate which concretes into 

 hard masses, matting the hair in tufts which are duly shed, or 

 forming thick, hard, yellowish scales or plates, beneath which 

 the skin is thickened and corrugated. The subjacent lymph 

 glands become swollen. Beneath the crusts and especially the 

 recent ones the symbiotes are found in numbers. The hair has 

 lost its lustre and elasticity and individual fibres show inequal- 

 ities in thickness from root to point. It is matted with scabs and 

 debris near the roots and proves unfit for combing. 



The disease makes a slow extension, and a lapse of months 

 may be necessary to show marked advance. 



The acarus, symbiotes communis var. capras, does not 

 differ materially in appearance from the symbiotes of horse and 

 ox. It can be readily distinguished from the sarcoptes of the 

 horse and ox, by the greater length of the rostrum and limbSj and 

 by the presence on the adult male of the two posterior abdominal 

 lobes, bearing the broad spathe-like prolongations. 



Treatment is by the usual anti-psoric liniments or ointments 

 after clipping and the softening and removal of the scabs by soap 

 suds and brush, with or without previous oiling. Delafond suc- 

 ceeded with simple alkaline baths : Ten pounds of carbonate of 

 potass or soda in 22 gallons of water.
