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."

 orderly application of the remedy. The hardened cuticle 

 and protecting scabs are safe refuges to the acari, there-

 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
