a question of mine,
in 'Journal of Horticulture,' 1862, pp. 225-242; also Mr. Bevan Fox, in
ditto, 1862, p. 284.

[493] This excellent observer may be implicitly trusted; _see_ 'Journal of
Horticulture,' July 14th, 1863, p. 39.

[494] 'Journal of Horticulture,' Sept. 9th, 1862, p. 463; _see_ also Herr
Kleine on same subject (Nov. 11th, p. 643), who sums up, that, though there
is some variability in colour, no constant or perceptible differences can
be detected in the bees of Germany.

[495] Mr. Woodbury has published several such accounts in 'Journal of
Horticulture,' 1861 and 1862.

silk-worm in China is given on the authority of Stanislas Julien.

Selection.

silk-worms taken to the Sandwich Islands were very irregularly developed;
and the moths thus raised produced eggs which were even worse in this
respect. Some were hatched in ten days, and others not until after the
lapse of many months. No doubt a regular early character would ultimately
have been acquired. _See_ review in Athenaeum,' 1844, p. 329, of J. Jarves'
'Scenes in the Sandwich Islands.'
