PREHISTORIC SITE AT BISHOP'S STORTFORD. 237 
their appreciation of Dr. Irving’s efforts to elucidate the difficult local 
problems in geology and archeology, and to record their satisfaction 
with the valuable work he has accomplished and continues to carry 
out in keeping definite records of local discoveries. Dr. Irving’s 
publications will show the nature and scope of his activities, but in 
this Report it is advisable to mention that he gave a general demonstra- 
tion (of the local geological conditions) to Dr. Haddon and the Secre- 
tary. In particular the gravel pit known as Frere’s pit was visited, 
and after the main exposure had been viewed, attention was directed 
to a trench in the Boulder-clay (above the gravel) in which prehistoric 
sherds and other objects were found in 1912 by Dr. Irving and his 
sons. A visit was paid subsequently to Gilbey’s gravel pit, and the 
remarkable fact was demonstrated that the Boulder-clay so conspicuous 
in Frere’s pit is absent from Gilbey’s, though the two are at most 
some two hundred yards apart, a ‘ river-drift ’ deposit occupying the 
horizon of the Boulder-clay. Dr. Haddon and the Secretary were thus 
enabled to gain a good idea of two typical exposures of the locality. 
In terminating this report Dr. Haddon and the Secretary have to 
express their opinion that under the present circumstances it does not - 
appear to them necessary that the special committee to investigate 
the prehistoric site at Bishop’s Stortford should be reappointed. 
Pal@olithic Sites in the West of England.—Report of the Com- 
mittee, consisting of Professor W. Boyp Dawkins (Chaitr- 
man), Dr. W. L. H. DuckwortaH (Secretary), and Professor 
A. KEITH, appointed to report thereon. 
THE members of the Committee visited various caves in the West of 
England during the early part of the present year (1913). 
Inasmuch as they have not been able to meet for the purpose of 
combining the results of their observations, the members of the Com- 
mittee ask to be reappointed without a grant. 
Anesthetics.—Fifth Interim Report of the Committee, consist- 
ing of Dr. A. D. Water (Chairman), Sir FREDERIC HEWITT 
(Secretary), Dr. Buumrenp, Mr. J. A. GARDNER, and Dr. 
G. A. BucKMASTER, appointed to acquire further knowledge, 
Clinical and Experimental, concerning Anesthetics—espe- 
cially Chloroform, Ether, and Alcohol—with special refer- 
ence to Deaths by or during Anesthesia, and their possible 
diminution. 
Durie the past year we have acquired further experience of the use 
of the chloroform-balance in the hospital and in the laboratory. Our 
opinion has been confirmed that this apparatus affords the safest pos- 
sible and the most convenient fixed means of inducing and maintaining
