iiient in local acariasis was iiotod several times by the authors, 

 Moiissu t'ound Tessier's mange bath (see page 953) effective 

 in cases of acariasis which were not very extensive; the ani- 

 mals are rubbed for 2 or 3 minutes with brushes while in the 

 bath and kept from licking- their bodies; cure resulted after a 

 month. Roth recommends operative treatment in cases of cir- 

 cumscribed disease, which consists in cutting the epidermal 

 layer horizontally with a sharp knife until drops of blood ap- 

 pear, the animal being narcotized; the places are then disin- 

 fected, and powdered with xerof orm ; a bandage is applied and 

 renewed after two days ; healing occurs after 5 or 6 days. Eber 

 has also seen favorable results from this procedure. In septi- 

 cemic symptoms Uel)ele saw surprising results from collargol 

 clysters (0.5:50 parts of lukewarm physiological salt solution). 

 In all cases the treatment is to be continued long enougli 

 until no fresh nodules or pustules arise and the skin regains its 

 healthy appearance. During the whole duration of the treat- 

 ment the animal nnist be nourished intensively, the stal)le must 

 be kept clean, and care must be taken that the treated parts of 

 the body are not licked. The affected animals must be sepa- 

 rated from the healthy ones, and after their recovery kept under 

 observation for a month ; on the appearance of suspicious signs 

 immediate treatment must l)e undertaken. Acariasis of the 

 other animal species may be treated in the manner recom- 

 mended for sarcoptic scab. Schenzle was successful in a horse 

 affected with general squamous acariasis with caraway oil solu- 

 tion (according to Gmeiner) while in Walther's cases a pro- 

 tracted treatment with a mixture of tar. glycerine and alcohol 

 was necessary. 



Considering^ the all too frequent failure of the treatment, Frohner and Schin- 

 delka consider that acariasis of the dog should lie included in those diseases which 

 are under legal supervision.

1. Ticks. (Ixodida.) Besides mange and hair sac mites, 

 the ticks are the most important temporary skin parasites in 

 the mammalia. They live in the open in nature, and the females 

 especially, if gaining access to the skin of animals, bore into 

 it with the rostrum. 



The most important varieties are : 



Ixodes ricinus (dog tick) which attacks hunting dogs from the month of 

 May to October, but is only exceptionally found in sheep and cattle.
