ON SYMPTOMS FOLLOWING TICK-BITES IN MAN. 
By GEORGE H. F. NUTTALL, F.R.S. 
The interesting Note by Dr Sant’ Anna, which precedes this paper, 
leads me to record some observations of a somewhat similar nature to 
those he has reported. My information is derived from three letters 
received fiom Africa, and from Dr Kindle. 
The first letter, dated 2 October, 1.909, was communicated to

and some watery material being squeezed out, after which a small sore 
is formed. It is generally fresh arrivals to the East Coast who become 
infected. Dr Campbell, of Durban, tells me that persons down in that 
part of the country are to a great extent immune; consequently, it is
