perhaps due to the anthrax bacillus. Kunjaeff also gives an 

 account of a case of a carbuncle on the thigh of a man, probably 

 caused by a tick (I. ricinus), the mouth-parts of which could still 

 be seen in the ulcer. 



Tick-Paralysis. 



The Australian cases of tick-paralysis given below are taken 

 from Dr. J. Burton Cleland's paper. Speaking of human infesta- 

 tion by ticks, this author says : " Along the Eastern Coast of 

 Australia, in parts where there are dense scrubs and tropical 

 jungle, it is not at all uncommon at certain times of the year to 

 find that ticks (Ixodes holocyclus) attach themselves to the human 

 subject. As a rule, beyond some irritation they produce no 

 particular ill effects, but every now and again a case is reported, 

 usually in children, in which severe symptoms have followed, and 

 sometimes even death." 



In Australia dogs and cats frequently perish from tick-paralysis 

 or poisoning. According to Bancroft, after the tick has been 

 attached to a full-grown dog for two or three days the animal 

 begins to look weary. Puppies travel away and are rarely found 

 alive again. Weakness in the hind limbs is first observed, and in 

 about five days from the attachment of the tick the dog becomes 

 unable to walk. Native animals in Queensland usually endure 

 the attacks of Ixodidae without ill effects of this kind, and animals 

 in infected districts are said to become tick-proof, for a single 

 attack confers immunity. 



A woman of forty living in Australia, on whom a tick was 

 found attached, is said by Bancroft to have become very weak 

 and to have developed ocular trouble. 



At Eden, on the south coast of New South Wales, a little girl 

 aged thirteen died from paralysis especially affecting the respiratory 

 tract, induced by the bite of a tick (almost certainly Ixodes 

 holocyclus). 



Strickland records the case of a boy in Australia who had the 

 misfortune to get a tick in his ear whilst in the bush. Four days 

 afterwards he became very sick and giddy, and after being put to 

 bed got much worse, all his muscles apparently being affected ; one 

 side of his face became quite crooked, and he could not walk without 

 assistance. The child was carefully fed and given medicine, and was 

 well again ten days after the tick was removed. Dr. E. M. Eaton 

 gives an instance of a tick biting a little girl in Australia and
