238 NOTES. (new edit. revised, 1883) we learn that at Ashdon, in Essex, a potter's kiln of this period was discovered by the Hon. R. C. Neville in 1852. It was of square form, being, as nearly as could be measured, 18 feet square, inclusive of the outer walls, &c., &c." Mr. Fitch said that he had seen the site of the supposed kiln, and was also dis- posed to consider it as one of the rubbish pits similar to those at Maldon and elsewhere. Mr. George Massee, F.R.M.S. (of the Museum at Kew, and Lecturer on Botany to the London University Extension Society), then delivered a lecture entitled "How to Commence the Study of Botany." The leading idea of the lecture was to indicate the sequence of study necessary to enable the student to estimate the relative value of observations and experiments, in order to obtain a clear idea of the structure and affinities of plants, and also of the influence exercised by the Vegetable Kingdom on the earth, and consequently directly or indirectly on animal life:—(1.) What is a plant ? (2.) Chemistry of plant-life. (3.) Physics of plant-life. (4.) Progressive evolution of plant-life, and its effects on surroundings. The lecture was illustrated with diagrams, and drawings on the black board.6 A short discussion was carried on by the President, Mr. White, Mr. Greatheed, and the Lecturer, to whom a cordial vote of thanks was given. Rare Birds in Essex.—It is stated in the "Essex County Chronicle," of December 27th, 1889, that the following birds had recently been placed in the hands of Mr. J. Pettitt, of North Street, Colchester, for preservation:—"On December 7th, at St. Osyth, Mr. Dale, farmer, brought down a good specimen, in full plumage, of the great bittern. A female specimen of the great grey shrike was killed near Halstead on December 9th, and on October 31st a young specimen of the little gull was shot at Brightlingsea. A short time ago Dr. Salter, J.P., brought down a spotted redshank on Tollesbury Marshes ; and on November 19th, at the same place, a fine specimen of the peregrine falcon, weighing 21/2 lbs., was killed." Birds attracted to Burning Ricks as to a Lighthouse.—"Hearing that many birds were seen flying round some ricks set on fire by lightning at Stebbing, in Essex, on September 2nd, I asked the Vicar (Rev. A. R. Bingham Wright) for details as to the species, in case you should care to publish them, and he kindly replied, as follows :—'My informant in charge of our fire-engine said these were a lot of larks (this probably would include sparrows, yellowhammers, greenfinches, &c), some plover (lapwing, no doubt), and some gulls. The place is about 20 miles from the estuary of the Blackwater. Another witness of the fire describes the two kinds of large birds (he was ignorant of their respective names) as wheel- ing above the ricks at different heights, each flock keeping to itself. I may mention that in stormy weather gulls are frequently about the fields here.'—J. E. Kelsall," in "Zoologist" for December, 1889. 6 In the circular calling the meeting it was stated that "the Council greatly desires that more would take up the practical study of one or other of the subjects included within the purview of the Club, and Mr. Massee's is the first of a series of discourses which will be promoted from time to time, with the object of inciting and advising members to the selection of lines of practical biological and geological study. It was forcibly pointed out in the last Presidential Address, and it is a matter of common knowledge, that our Field Meetings are not so useful and instructive as they might be, owing to the want of some kind of elementary knowledge of the subjects brought forward, or the objects seen, on the part of these attending. If encouragement is given, the Council hopes to make some arrangements to enable members to remedy this defect; but to render these efforts successful, the members must show a desire to learn, and willingness to undergo the necessary training, and to obtain the books and instruments.
