and recognized disease in the man or animal attacked by the tick. 
The Note by Dr Sant’ Anna and the letters I have quoted point to 
a fairly definite train of symptoms following the attacks of certain ticks, 
and it appears justified, at least provisionally, to give to the condition 
the name of “ tick-hite fever!' The effects may ultimately prove to be 
due to either a toxin emanating from the tick or to a specific virus. 
We can scarcely refer to it as “tick fever,” for this name has already 
been applied to African relapsing fever and Spotted Fever of the Rocky 
Mountains in man, and to the various diseases in animals due to 
Spirochaeta, Piroplasma, Nuttallia and Theilei'ia. The name “ tick 
fever” has, therefore, lost all significance, and should be dropped from 
our nomenclature.
