depth of 2,435 fathoms, the surface temperature being 65.5 Fahr., 
bottom temperature, 35.5 F. ; pressure equal to 457 atmospheres, 
or nearly three tons to the square inch. The ooze consisted of 
calcareous mud, containing Globeriginze and Foraminiferzx. 
Dr. Hauirrax exhibited a number of very beautiful micro- 
photographs, taken by himSelf, some of the most striking being : 
stomach of owl (40 diam.) showing the glandular structure ; teeth 
of medicinal leech (480 diam.) in which the true nature of the 
teeth was well shown ; sections of the proboscis of the blow-fly, 
one transverse the other vertical, intended to exhibit the rasping 
teeth in the centre of the disc—in the photographs they were 
almost isolated and stood out very conspicuously ; poison bag of 
spider, with poisonous fluid exuding therefrom,—(in mounting, a 
slight pressure on the covering glass had caused the poison fluid to 
exude); a curious spine of echinus, trache of silk-worm, and 
tongue of bee. 
Mr. Wonror exhibited cluster cups on the dog-violet and 
common nettle ; cast of owl, consisting of fur and bones of mice ; 
and cocoons and eggs of the emperor moth, Saturnia Carpini, and 
forty-three males of the same moth, attracted in two days at Pole- 
gate and Tilgate by one female ; and read a paper on the power 
possessed by some female moths of attracting the males of the 
same species in great numbers and from long distances. 
The Saturnia Carpini belonged to a group, the females of 
many of which are noted for the peculiar property they possess of 
collecting, or, as the old entomologists named it, ‘‘sembling” the 
males from long distances. Some consider the females emit an 
odour perceptible to the sense of smell in the opposite sex, 
though the existence of such an organ has not yet been satisfac- 
torily localized by naturalists. Be that as it may, they certainly 
have the power of drawing from long distances, and in great 
numbers, the males of the same species, who, as it were, intoxi- 
cated, rush wildly after the females, heedless of danger, and 
allow themselves to be captured with the greatest ease. Nay, 
what is more strange, few persons walking over districts where 
these creatures abound ever see them, unless they are provided 
with a virgin female, and then, under favourable circumstances, 
and always against the wind, the males come flying up singly, in 
twos and threes,
