claws, become infected, and shortly provide a fresh 
colony of acari ready for further attack when the dog 
again visits the spot. If the reader has attentively 
studied the paragraphs dealing with the symptoms of 
erythema and eczema, he will be able to realise by the 
changes produced by the parasite how rapidly the dis- 
organisation proceeds, constituting true forms of those 
diseases. The parasite burrows beneath the. cuticle, and 
may be found on raising the scabs which cover the 
wounded parts. This is the sure diagnostic sign of the 
disease, and the essential proof that it is not simple 
eczema or ‘red mange.” 
Treaitment.—Successful issues attend only diligent and 
orderly application of theremedy. The hardened cuticle 
and protecting scabs are safe refuges to the acari, there-

barriers must be removed. ‘The affected animal should

and cleansing. The owner need not be in haste to

him, and, with fresh additions of heated water after the 
first washing, it will be advisable to include one or two 
teaspoonfuls of “ Sanitas” Oil mixed with an equal bulk 
of glycerine. Next comes the operation of dressing. 
The dog is removed from the bath, carefully drained 
under protection from the cold, and the dressing, what- 
ever it may be, is patiently and carefully rubbed in. In 
order to realise how much of both is required, the opera- 
tor must endeavour to think how he would like to have 
it done to himself under similar circumstances. The 
process will be needed at intervals of at least three or 
four days, long hair being carefully removed, or even 
entire shaving must be resorted to. A muzzle should be 
in readiness to prevent the animal using his teeth. We
