We cannot believe Mr. Wheeler when he says that the absurd 
trust in the Jennerian rite leads to “ recklessness and foolish 
exposure.” Our observation tells us that the vaccinated and the 
unvaccinated alike shun any person whom they suspedt of having 
been in contact with a smallpox patient, or of coming from a 
house where the disease exists or has lately existed. It seems 
to us that most people err rather by exaggerated caution than by 
over confidence. ... r 
We think that the fairest way of ascertaining the value, ot 
vaccination as a prophylactic would be for the present agitation 
to be suspended. If the entire community were duly vaccinated, 
and if smallpox epidemics still occurred, we should then be 
warranted in questioning the value of the “ rite. We fear the 
basis of the anti-vaccination “ movement” is not medical, but 
political. There are people, we fear, who consider themselves 
entitled to cherish diseases if they feel so inclined, and who 
regard vaccination, however efficacious, as an inioad on theii 
“ liberties.”

This issue contains a continuation of Mr. A. E. Hudd’s Cata- 
logue of the Lepidoptera of the Bristol District. Here we find 
mention of the disappearance of Solenobia pomonce, formerly 
plentiful. It appears that hundreds of specimens bred by the 
author, by Mr. Harding, and Mr. Vaughan were all apterous 
females, not a single male having appeared during several years. 
Depressaria pallorella , formerly common near Bristol, has be- 
come scarce. Of (Ecophora pseudospretella we find it recorded 
that Mr. Vaughan bred a series of specimens from a wax-candle 
a fadt which opens up some difficult questions in chemical 
physiology. . ... ,, 
The butterflies of the Bristol district — 55 species — include all 
those recorded by Mr. Barrett for Norfolk, and in addition P. 
daplidice, L. sibylla, L. arion, L. adonis, N. lucina, and 
H. comma. Of the Noaurni, Bristol has 73 species as against 
74 in Norfolk, and of Noauae 213 against 225. No fewer 
than 35 of the Norfolk Noauae have not been seen in the Bristol 
distria, which, on the other hand, has 27 species not recorded 
by Mr. Barrett. The total number of species of Lepidoptera 
recorded for Yorkshire is 1341, for the Bristol Distria 1310, and 
for Norfolk 1246.
