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 Booking, 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.
