THE ESSEX FIELD CLUB. 29
and he proposed that a resolution to this effect should be sent by the
Secretary to the members of Mr. Rudler's family. This was cordially
agreed to.
Letters were received from Miss Cooke in response to the letter of
regret and sympathy on the death of Dr. M. C. Cooke, and from Mr. B. W.
Bryan, in acknowledgment of a like letter on the death of Colonel Bryan,
C.E.
Presentations.—Books for the Library were presented by Mr. W.
Whitaker, of John Burrough's edition of White's "Selborne" (Macmillan,
1895), and by Mr. T, W. Reader, of Kirby and Spence's "Introduction
to Entomology" (1818), and the Curator announced that Mr. H. S.
Tabor, of Bocking, had again made a presentation to the "Pictorial Survey"
consisting of 49 local photographs, of Mr. Tabor's own taking, and 44
Pictorial Post-cards, and Mr. J. Tertius Smith had presented a clutch of
eggs of the Water Rail (Rallus aquaticus) from Hickling, Norfolk. Thanks
were accorded to the several donors.
Variation of Flowers of Ulex europaeus.—Mr. Wm. Howard
exhibited a variation of the flowers of Gorse upon a bush situate in Roding
Lane, Chigwell (see Note in the present part of Essex Naturalist).
Observations were made by Mr. Paulson and Mr. C. Nicholson.
Paget Colour Photography.—Mr. Henry Whitehead, B.Sc., exhibited
a number of lantern slides prepared by the Paget Colour Photography
Process. The speaker commenced by explaining the general principles
involved and then proceeded to show a number of slides in the lantern.
Some of these were photomicrographs of animal and vegetable preparations
and crystals under polarised light, all of which had been kindly lent for
the occasion by the Paget Prize Plate Company. Mr. Whitehead then
exhibited some slides of his own making which were chiefly British Wild
Flowers in their natural surroundings, scenery, etc.
In concluding it was pointed out that two great merits of the process
were its simplicity of manipulation and its cheapness as compared with
other colour processes. Only one negative was necessary and ordinary
prints and bromide enlargements could be made from it. The most
expensive item was the viewing screen, and this was only required when a
satisfactory positive had been obtained. Another advantage was that
an indefinite number of duplicates could be obtained.
The speaker said that his object in taking up the process had been to
provide himself with slides of British Wild Flowers suitable for demon-
stration to a class of students of Botany, and he considered that the results
had fully justified his expenditure of time and money.
Remarks were made by the President and Mr. Whitaker, who com-
mended the process to the geologist from its simplicity and inexpensiveness,
and the differentiation which the pictures afforded of the different strata,
by Miss Willmott, F.L.S., and others; and Mr. Whitehead was cordially
thanked for bringing this subject forward.
Mr. W. Whitaker, F.R.S., then exhibited a long series of lantern-slides
illustrating the geology Of the British Isles, belonging to the Geological
Photographs Committee of the British Association. Mr. Whitaker made
interesting running commentaries on the slides, pointing out the special
points of interest of each, and he was heartily thanked for his expositions.
