Leucocytozoa 
There are other remarks in Mr Wenyon’s paper to which exception 
might easily be taken. Some of these arise from consideration of 
sentences in my article isolated from their context. Such a procedure 
is more compatible with the political arena than with scientific research. 
I will not weary my readers with further details. 
In conclusion, I would cordially thank Mr Wenyon for the great 
honour he has done me in bringing into prominence my modest article 
on the Leucocytozoa, wherein I naturally considered all the parasites 
which had ever been so designated. The article, as Mr Wenyon knows 
quite well, was of a slightly popular nature, in which controversy—that 
adds glory to neither party—could not be set forth at length. At any 
rate, my article has served one purpose at which I aimed, that of 
drawing “ attention to an interesting group of parasites.”
