A FAILURE IN THE PRODUCTION OF HONEY. 
To the Editor of the Journal of Science, 
Sir, — Bee-masters in the London districft, as well as in Buck- 
inghamshire, Northamptonshire, and other parts of the Midlands, 
complain that their hives have been this season totally unpro- 
ductive, and that the bees, instead of having any honey to spare, 
will require food to support them through the winter. Can this 
be due to some disease among the insedts, to a lack of flowers, 
or to some peculiarity of the weather ? — I am, &c.,

EFFECTS OF DARKNESS ON ANIMALS. 
To the Editor of the Journal of Science, 
Sir, — How is it that mice, though spending their lives in abso- 
lute darkness, neither lose their colour nor their eyesight ? They 
seem to me to have quite as little need of sight as has the mole, 
yet disuse of the faculty does not seem to lead into degeneration 
of the organ. — I am, &c., 
C. G.
