ORGANIC GEMS IN MARINE DEBRIS.

Many otlier forms, alas ! I also saw, but was un- 
able to identify ; exquisite organisms only indicated 
by stray fragments and detaclied members, the 
minute anatomy of which was very elaborate. How 
the fragile shells of Bulla, which were somewhat 
numerous, had escaped destruction from the rolling 
stones among which they lay, Avas to me a mystery, 
although 1 easily imagined their safety ensured 
from the buffetings of the waves by reason of their 
lio-htness. From the same cause the shells of lan- 
thina were cast ashore here in a perfect condition. 
As for the milk-AAdiite Aventletraps and polished 
Eulimae, and the tribe of tiny Kissoids which I 
likewise disentombed, they were once living inhabi- 
tants of the giant Laminarife that now lay rotting 
on the beach. The Foraminifera or Ehizopods 
were very abundant in some portions of this 
marine debris, and as the eye alighted upon their 
highly sculptured forms, Avhen scanning under 
the lens this mass of crude fragments, I Avas quite 
startled to see the contrast betAveen the rude inor- 
ganic bodies and the perfect results of animal life.
