In conclusion, I am very sorry to be forced to state this, but the fact 
of the matter is that Dr Woodcock has lost the perspective of his subject. 
He has worshipped so long at the shrine of Schaudinn and worked on 
cultures of trypanosomes that his view is narrow and biassed. He 
generalises on one or two instances, as witness the general hypotheses 
he raises on the investigation of the life history of T. lewisi, and having 
proceeded to generalise, he cannot resist meddling with the work of 
others. I would suggest that the study of a standard work on Logic, 
particularly Inductive Logic, and especially the chapters dealing with 
Fallacies and Generalisations would be of distinct value to the gentleman 
who so airily talks of “ logical views,” “ onus probandi,” etc. However, 
I cannot further waste my time in dealing with wild hypotheses founded 
on a basis of illicit generalisations.
