THE ESSEX FIELD CLUB.

had ever seen. It comprised nearly all the British Pyrales and Crambi, 
and all the Tortrices with the exception of a dozen or eighteen species 
practically unprocurable. Each moth was set on a silver pin, and then 
mounted on little slabs of artichoke pith. These slabs were stuck again 
with a stouter pin so as to avoid damage on removal of the specimens. 
Every insect was accurately named, with full data. Mr. Cole added that 
the above collections were a valuable and instructive addition to the 
museum. 
Dalyellia diadema Hoftsten.—Mr. Henry Whitehead, B.Sc., exhibited 
Essex specimens of this Turbellarian. The species appears to have been 
recorded only once before, viz., in the Bernese Alps. Mr. Whitehead gave 
some particulars of this interesting form. (See “ Notes.") 
A Lecture was given by Mr. Hazzledine Warren, F.G.S., on " Pre¬ 
historic Art." The lecture was abundantly illustrated by lantern slides. 
A cordial vote of thanks was given to Mr. Warren for his exceedingly 
interesting lecture. 
Dr. Alexander Graham gave a demonstration by means of actual 
specimens and drawings on the blackboard of points in the structure of 
the human skull, as compared with the skull of Eoanthropus dawsoni 
shown to the members by Dr. Smith Woodward, at the Meeting at the 
British Museum on 12th April last. The demonstration was of too 
detailed a nature to be reported upon without the aid of drawings. 
The President pointed out the very interesting nature of Dr. Wood¬ 
ward’s and Dr. Graham’s discussions, and a vote of thanks was passed to 
Dr. Graham. 
It was announced that our Member, Mr. Fred Enock, F.L.S., had 
presented to the Library over 300 pamphlets and reports relating to 
economic entomology.

CAMBRIDGE BOUNDARY OF THE COUNTY (THE CHALK 
DOWNS OF ESSEX). 
Saturday, 31ST May 1913. 
This excursion was organised to enable the members to visit the chalk 
Lynchetts at Ickleton, the burial mounds of Bartlow and other interesting 
points on the Northern boundary of Essex. 
The conductors were Mr. W. Whitaker, F.R.S., Mr. G. Morris, B.Sc., 
Mr. Guy Maynard, and others. 
The assembly was at Audley End station at 9.45 a.m. Here a group 
photograph was taken, and entering brakes the party drove up the Cam 
Valley. Opposite Audley End House a halt was made, and, without 
alighting, Mr. Guy Maynard pointed out the ancient Guest House, British 
Camp, etc., and explained the original forward extension of the Mansion 
towards the water edge. 
At Littlebury a stop was made to inspect the base of a church-yard or 
village cross now inserted in front of Gate House Farm. This showed a 
curious design of a flowering heart, the Tudor Rose, and two kneeling
