It is readily raised, loAvered, or, if thought desirable, re- 
moved altogether from the lamp. 
It can be made cheaply. Mr. Baker, of High Holborn, is 
taking steps to produce this shade, and will, I have no doubt, 
be able to supply it at a trifling cost. — Henry F. Hailes. 
Dr. Woodward’s Paper in the October Number.— Mr. Glaisher, 
in his late address to the Microscopical Society, states that 
Dr. Woodward’s paper on Roberts’ test-plate was published 
in the Journal without acknowledgment of its having been 
sent for publication by the Society. This is very true, 
because it was not sent for publication by the Society, but 
was published by Dr. Woodward’s special request in the forth- 
coming number of the Journal. 
Snow Crystals. — A Mr. Charles Belcher, of Bedford, has 
made the startling discovery (!) that snow consists of crystals, 
and has written a letter on the subject to the ‘ Times.’ The 
leading journal, with its characteristic appreciation of scientific 
fact, publishes the astounding announcement (!) Is not this 
a powerful argument in favour of science-teaching in our 
schools ? — Scientific Opinion. 
The Fauna of the Gulf Stream at Great Depths. — The in- 
vestigations ordered by the new Superintendent of the Coast 
Survey, Professor Pierce, of Harvard College, into the marine 
fauna of the Gulf Stream, in connection with the regular 
duties of the survey, have begun to produce their natural 
result, in such valuable contributions to science as we have 
now before us. The line of the present survey was “ in a 
section between Key West and Havana, incidentally with 
the purpose of sounding out the line for the telegraph cable.” 
Although the work was interrupted, and the casts made with 
the dredge few, “ the interesting fact was disclosed that 
animal life exists at great depths, in as great a diversity 
and as great an abundance as in shallow water.” By 
two casts in 270 fathoms off Havana, Crustacea and worms, 
numerous dead shells of gasteropods and pteropods, living 
terebratulae, and seven species of bryozoa, besides echini, 
starfishes, and an abundance of corals, hydroids, and 
foraminiferse, were taken. Only one species of seaweed, 
however, was mixed with this luxuriant animal life, which 
corresponds with similar results of deep-sea dredging in the 
European seas, and shows that “ the greater number of deep- 
sea animals must be carnivorous.” They found, also, that a 
porous limestone was in process of formation, “ composed
