The Sea-horse and its Young.—We in England have lately had 
the opportunity and pleasure of seeing those extraordinary little. 
fish the Hippocampt alive, and supported by their strange pre- 
hensile tails clasping rocks or corals, in the aquaria of the Zoological 
Gardens in London. In the ‘American Naturalist,’ we read an 
account of the habits and young of the American Sea-horse, written 
by the Rev. Samuel Lockwood. He had long wished to ascertain 
in what condition the young first appeared, and had repeatedly 
failed, owing to the death of the males which he obtained. In 
these fish, and also in the Pipe-fish and Pegasus, the female lays 
her eggs into a cavity of considerable size, which is placed along 
the tail of the male, and there the eggs remain until they are 
hatched, when the father squeezes them out of his pocket. Mr. 
Lockwood believes that the walls of this pocket in some way or 
other furnish nourishment to the ova, since they increase so largely 
while within it. After many failures he obtained a Hippocampus 
which did not prematurely turn out his young, but squeezed them 
out duly—active, transparent little creatures—to the number of 
several hundreds. Immediately on coming into the water the 
young fish began to use its prehensile tail, and curious mishaps 
were noticed—two or three often intertwining their little hair-like 
caudal appendages, and pulling in opposite directions. Mr. Lock- 
wood did not succeed in rearing his young troop of Sea-horses, nor 
did he examine them with the microscope, which he should have done. 
A Fish living inside a Gigantie Sea-Anemone. — Whilst 
searching about for animals on the shores of the China Sea, Dr. 
Cuthbert Collingwood saw an enormous blue sea-anemone, two feet 
in diameter, and a little fish swimming near it. On raking out the 
inside of the anemone with a stick, six other little fishes swam out 
of it, and these he caught with a hand-net. Several times he saw 
these anemones and their fish, but unfortunately the specimens of 
the fish he brought were destroyed. In the ‘ Voyage of the 
Astrolobe,’ a fish is mentioned as living inside a Holothuria, and 
several of these were seen by Dr. Collingwood about Labuan. But 
the fish which goes inside the sea-anemone is distinct from this 
species. Mr. Low, of Labuan, kept one alive for some months in 
a tub without the anemone, which seems to show that its habit of 
taking shelter within the capacious stomach of that benevolent 
creature is not a necessity of its existence. Fishes which inhabit 
the body cavities of large meduse are well known even on our own 
coasts. The writer saw such a medusa and fish recently in the 
Channel Islands. 
The Silkworm Delusion.—In an interesting new magazine, by 
name ‘The Student,’ Mr. Shirley Hibberd gives an account of an 
attempt at silk cultivation in Britam. He describes how an estate 
of a thousand acres was bought, and carefully planted with the
