of the leaf and the traces of insect puncture, either by leaf-miners or by
the dipteron, Hormomyia piligera, which produces the hairy tubular galls
on the upper surface of the leaf. It would seem as if the presence of the
insect-larva in the leaf-tissue was associated with some secretion (whether
caused by the parent when inserting its egg in the leaf, or by the larva
itself during active feeding) which tended to arrest the decay of the leaf-
chlorophyll immediately surrounding it. The benefit of such arrest to
the developing larva, by conserving its food supply until it attained its
full growth, was obvious : but detailed investigation of this curious
phenomenon by chemists was necessary to demonstrate the presence of
such a secretion as was suggested.
Other entomological finds were a male specimen of the Feathered
Thorn Moth, at rest on an oak trunk, several beetles (Helops striatus)
under the loose bark of old trunks, and specimens of the neuropteron,
Boreus hyemalis, amongst moss. The curious little Myriopod, Polyxenus.
lagurus, was also found under loose bark.
ORDINARY MEETING (649TH MEETING).
SATURDAY, 24TH NOVEMBER, I92S.
This meeting was held as usual in the Physics Lecture Theatre of the
Municipal College, Romford Road, Stratford, the President in the chair.
Over sixty members were present.
Miss Nellie Carter, D.Sc., F.L.S., cf the East London College, Mile End
Road, E.1 ; Miss Annie Hopkins, of 32, Wanstead Park Avenue, E.12 ;
Miss Edith M. Lister, of Sycamore House, 871, High Road, Leytonstone,
E.11 ; and Mr. John Robert Avery, A.C.A., F.S.S., of Compton, Roebuck
Lane, Buckhurst Hill, were elected members of the club.
Mr. Avery, sen., exhibited water-colour drawings of Waltham Abbey,
Latton church and Nettleswell church, also a print of the cut brick panel
on the exterior of the last-named church ; and presented the latter to the
Club. He also exhibited a curious form of marriage certificate, customary
among members of the Society of Friends ; this certificate recorded the
marriage of William Alfred Smee and Jane Pearson Wilson, solemnized
on 1st September, 1853, at Kendal, and bore the signatures of no less
than seventy-nine witnesses to the ceremony !
Mrs. Hatley exhibited and presented to the Club two original pencil-
drawings and a key-map of the buildings of Pimphall Farm, Chingford,
prepared by herself, together with several lantern-photographs of the
farm, which bears the date 1576 over the porch. Mrs. Hatley gave
an interesting resume of the history of the Manor of "Pimps," from
which we quote as under :—
The farm known as "Pimphall" is an interesting historical property,
possesses marked characteristics, and is a good specimen of Essex manor-
farm house, situated one mile E.N.E., of Chingford Old Church.
Originally there were but two manors in Chingford parish. Part
of the manor of Chingford Comitis (or Earls, so called after its one-time
owners, the Bourchiers, Earls of Essex) was, in the 14th century,
reckoned as another manor and called "Gowers and Buckerells" (alias
Pimps Manor").
