FISH 



Hermaphrodite Haddock. — A few days 

 ago, whilst a fish Shaddock) was being pre- 

 pared for dinner, my attention was drawn 

 to a very peculiar circumstance, the fish 

 containing both milt and ova, lying side by 

 side, and fully developed. There is no 

 doubt it was a hermaphrodite fish. — H, 

 Andrews, Aldborough, Borobridge. 



QUERIES. 



24. 



Have birds any additional sense that 

 enables them to find their way when 

 migrating ? — J.O. 



25- 



Is it true that every mole has a castle ? 

 and if so what is its use ? That every mole 

 makes a fresh castle every year, as Mr. 

 Osborne stated in his " Life History of the 

 Mole," is surely not the case, for moles' 

 castles, instead of being very numerous, 

 as they would be in that case, are, in reality, 

 very scarce. I should also like to call 

 attention to the unanswered question about 

 mole marks in the snow, in Y.N., vol. ii., 

 page 187. — F. E. Prescott Decie. 



26. 



Have any readers of the Y.N. ever tried 

 to kill butterflies or moths by keeping them 

 "in vacuo," and if so how did it succeed? 

 Unfortunately, I do not possess an air-pump 

 and so cannot try this myself. Has any one 

 ever tried to kill them by an electric shock ? 

 This I can try myself, and I intend to do so 

 in a short time, unless it has been already 

 tried, and found impracticable. — F. E. 

 Prescott Decie. 



REPLIES. 



16. 



Removing Scales from Lepidoptera. 

 — I have accomplished this in the following 

 manner :— First I relaxed the specimen by 

 putting the wings between sheets of damp 

 blotting paper. I then placed the wing to 

 be operated on upon a card, and brushed 

 the scales away from the underside, I then 

 gummed another card, and placed the de- 

 nuded side upon it, subjecting it to a little 

 pressure till dry. When dry there is no 

 difficulty in brushing away the scales on the 

 upper side. — S.L.M.
