wrong ; and the error lies in stating this 
inference, whether right or wrong, as an 
observation. 
As an instance of another class of 
errors, 1 would mention a case which 
occurred a short time since. Most of 
your readers will recollect a paper on 
digging for pupae, which gave such an 
impetus to that mode of collecting. 
While that paper was being read before 
the Society, a friend sitting by me said 
“ I know some people who get numbers 
of pupae from hedge-rows;” and almost 
immediately after came the dictum of the 
author, “ as for hedge-rows, it is no use 
trying them.” The error in this case 
arose from drawing a conclusion from 
unsuitable observation : the information 
sought to be given was the comparative 
value of different localities for pup®; 
and the only observations from which 
such an inference could be justly drawn 
would have been those in which each 
locality had its equal share of attention, 
which in this case it evidently had not. 
This, however, is an error from which 
few are exempt, and from it arise all 
those strange partialities for particular 
times, or places, or trees, which some- 
times produce such strange results. 
Hearsay descriptions I have not 
noticed, for a person trusting to them is 
almost certain to go wrong ; nor have I 
mentioned errors of reasoning, for they 
belong to the higher walks of science, 
and would be foreign to the subject in 
hand ; but I shall be glad if what I have 
said has the effect of lessening that mass 
of error which arises from causes so 
readily prevented.
