some ones secrets, or (7) of freeing something from worms, or (8) of

oyster or mussel, or (10) of giving something a spiral form, or (11) of

Some other word seems necessary. One cannot use the term “ larvate,” 
for that is already in use, as a past participle in speaking of certain 
peculiarities of diseases that physicians meet with, and as an active 
verb in expressing the idea of masking. 
The term “ delarvate,” the etymology of which is evident, is not to 
be found in the dictionaries and is here proposed as an English equiva- 
lent of the French échenillage. In his notes and manuscripts the 
author has used it constantly to avoid paraphrasing, and has gained 
time in so doing. Is the word not of sufficient value for general use?

Dr. Smith’s Study of the San Jose Scale.—At the 1896 ses- 
sion of the New Jersey Legislature, $1000 was appropriated to the 
State Experiment Station for the study of habits and enemies of the 
San José scale (Aspidiotus perniciosus) with a special view to the use- 
ful introduction of the latter into New Jersey. Dr. J. B. Smith was 
commissioned to make the investigations. In the Station report for 
1896 Dr. Smith gives a full account of his studies and an admirable dis- 
cussion of the subject. He visited Californiain May and found a great 
division of opinion regarding the usefulness of ladybird beetles as 
‘destroyers of this scale. ,But he found that “ there is absolutely no dis- 
agreement concerning the beneficial effects of the Vedalia cardinalis 
(Fig. 1) as against the Cottony Cushion scale Icerya purchasi. There 
is no doubt that this insect, once so destructive, has been almost com- 
pletely exterminated by the Vedalia. We do find that occasionally 
the scale reappears; but a colony of the beetles sent from the office of 
the local commissioner usually clears them out in a few weeks there-
