TO CORRESPONDENTS, 
M. G., Richmond. —Guinea-pigs should be given a vegetable 
diet ; feed on barley-meal and oats with a little cabbage ; green 
food, however, should be given sparingly. They are very 
susceptible of cold and should be kept warm and dry. We 
regret we cannot give a separate article on this subject. 
Mr. J. F. Cordon, 16, Ironmonger Row, Old Street, St, 
Luke’s, E.C., will be glad to correspond with any other readers 
of the Naturalists’ Journal who are interested in Entomology 
with a view to mutual assistance and intercourse. We shall be 
pleased to hear from any other readers who wish a similar 
publicity. 
H. P., Bayswater.—R eceived ; the early pupating is no 
doubt owing to the fact that the season is a very early one, 
G. W., Clapham. —-We mentioned the fact of mice eating 
eggs in the May number (p. 128). It is hard to sav whether 
the bird mentioned was a cuckoo—an eye-witness (Dr. Jenner) 
has stated that he saw a young cuckoo eject three young birds 
within two days of hatching iand our own experience is almost 
similar, but even quite recent authorities have stated that it 
does not take place until the cuckoo is eight or nine days old. 
As to the moths they may be stuffed if desired by drawing out 
the contents of the abdomen with a fine hook (as soon as killed) 
and filling the cavity with cotton. 
F. P, P., Charing Cross.— -Many thanks for your interesting 
account of the Lambeth Field Club’s outing • it shall appear 
next month. 
W. G. C,, Thetford. —Shall appear next month, 
M. B., Bellagio, —Shall appear in August or September
