NITROUS OXIDE AS AN ANAESTHETIC. 
These men, like those who go down to the sea in ships and do business in great 
waters, see the works of the Lord and his wonders in the deep. 
To those of our own calling, laborious Chemists and Druggists, these remarks 
are most earnestly commended. Already we number amongst us some microsco¬ 
pic workers. Deane* of Clapham, cut nomen apud nos semper est in honorem , 
Brady f of Newcastle, Schacht of Clifton, Stoddart of Bristol, Clift of Lew¬ 
isham, Tylee of Bath, Martin of Redland, Waddington and many others, not 
forgetting one who though a dispensing chemist in a cathedral city is not un¬ 
favourably known to the Rev. J. B. Reade. Let me try, not without strong 
hope, to extend the list. King’s College, London, is the present home of the 
Royal Microscopical Society.

The Library of the Society, at King’s College, is open for use, together with 
the collection of objects, microscopes, etc., on Mondays, Tuesdays, Thursdays, 
and Fridays, from 11 a.m. to 4 p.m. ; on Wednesdays in the evening only, from

NITROUS OXIDE AS AN ANAESTHETIC. 
As nitrous oxide is now being used largely in this country, it may not be out 
of place to say a few words for the benefit of those who may be called on to 
make the gas. As most of the readers of the Journal are aware, this gas has 
been used largely in America as an anaesthetic, and at the present time the den¬ 
tists in England are investigating its effects, and probably it will become a 
favourite agent in the place of chloroform for short operations, such as the 
extraction of teeth. 
It may seem strange to some that nitrous oxide should come so suddenly into 
* Xanthidia and Polythalamia (foraminifera) found in the grey chalk between Folkestone 
and Dover. (Oct. 15, 1845.) 
On the first discovery of Xanthidia in flint so great was the anxiety to obtain specimens 
that several tons of flints were broken up in order to find them, hut Mr. Deane obtained them 
from the chalk containing no flint nodules. In one piece of a greyish kind of chalk no less 
than six species were found by treating it with hydrochloric acid. They were accompanied 
by Polythalamia and the remains of other organized bodies called Potalia—he proved that 
the Xanthidia possessed a horny skeleton. 
Vibrio Tritici. (Jan. 1863.) 
Physical Characters of Magnesia. (Pharm. Journ. Vol. 8, p. 266.) 
Papers read at the British Pharm. Conference on Microscopic Analysis Applied to Phar¬ 
macy. (Joint author.) 
Mr. Deane also worked for and with Pereira, some of the drawings in the last edition of 
the Materia Medica being made from his preparations.

a new Genus of Foraminifera, with Notes on Structure and Affinities.
