consist of a head anri body, which latter terminatea in a long and 

 obtusely pointed tail. They are furnished 'nith six or eight legs 

 situated on the anterior part of the body, three or four on each side. 

 The head consists of two antennse and a median proboscis, all of 

 which are capable of being moved forwards and backwards. The 

 legs consist of three segments. The movements of the creatures 

 are not often seen, and are very slow. The parasite measures 

 about one-hundredth of an inch in length by one five-hundredth in 

 breadth." 



In regard to treatment, Fleming, in " Veterinary Sanitary 

 Science," says : " The situation of the DemodRx renders it almost 

 inaccessible to parasiticidal remedies ; the disease it engenders is 

 therefore looked upon as extremely troublesome, and, in the 

 majority of cases, almost beyond a cure. Often, when it is believed 

 to be extinguished, it reappears in all its virulence in one or two 

 months. Nevertheless, Ziim asserts that he has frequently 

 succeeded with an oLatment composed of 1 part of benzine to 

 4 parts of lard. Weiss recommends the inunction of essence of 

 juniper. Zundel states that the balsam of Peru has often yielded 

 good results when the malady has not been of too long duration ; 

 he has employed it dissolved in alcohol (1 to 30) ; he has likewise 

 used the green ointment of mercuiy with success, aa well as the 

 nitrate of silver ointment. Hofer speaks highly of an ointment 

 composed of carbolic acid and Vogel prescribes a solution of caustic 

 potash." 



Messrs. Hunting and Buguid, after many unsuccessful experi- 

 ments, adopted the plan of softening the skin and breaking up the 

 outicular covering by the application of oil and caustic potash. The 

 following is Mr. Hunting's formula: "Creosote Joz. ; olive oU, 

 7oz. ; liquor of potash, goz. ; first mix the creosote and oil, and then 

 add the potash, mixing them by agitation. ' ' With this the affected 

 spots should be dressed twice a week, allowing longer intervals when 

 tie skin becomes soft and tender. Mr. Hunting says a cure i-equires 

 fi-om three to eight months, and a longer time allowed for the growth 

 of the hair. 



I have had some experience of Follicular mange, but principally 

 with pugs. In one case I had two sent to me in a very bad state, 

 and both eventually became eatii-ely denuded of hair. The treat- 

 ment I adopted was washing — I might say soaking — the dogs in a 

 strong lather of soft soap, hot water, and pearl-ash, carefully drying. 

 One, the youngest, I painted over with a solution of iodide of po- 

 tassium, loz. in a pint of water, and after allowing it to dry, applied 

 very freely Spratt's Mange Lotion. To the other, after drying, I 

 applied the lotion witiiout the solution of iodide of potassium, and
