The actual work appears to have begun in the summer of 1704, for under date August 10th, he writes to his friend and patron, Sloane : " I am now entering upon an history of insects, for which you would have been a far fitter person; having, what I want, your senses entire, your strength firm, your understanding and memory perfect," as having " already published the Histories of Birds and Fishes, and a Synopsis of Quadrupeds, there remains but that of insects to complete the History of Animals." Truly a marvellous man ! for this task was taken up long after he had passed the allotted span—the three score years and ten. To Dr. Derham he writes, under date Sept. 6th, 1704 : " The work which I have entered upon is, indeed, too great a task for me ; I am very crazy and infirm, and God knows whether I shall over-live this winter. Cold weather is very grievous to me ; besides, 1 have not bestowed sufficient time and pains in the quest of any tribe of insects except papilios, and I have told how far short I am of perfection in that. I rely chiefly on Mr. Willughby's discoveries and the contributions of friends, Mr. Petiver, Mr. Dandridge. Dr. Sloane, Mr. Morton, Mr. Stone- street. As for my own papers on this subject, they are not worth the pre- serving ; and Mr. Willughby's must be returned to his son, Sir Thomas Willughby, from whom I had them with promise to return them if I did not make use of them." Doubtless Ray overtaxed his strength in the production of the work We are chiefly concerned with, and he was justly disappointed that the publishers would not accede to his demand for " thirty pounds in money, and twenty copies to present my friends." Little enough recompense for the life-work of such a man. The author himself under- took to use his best endeavours to procure subscriptions. As he expresses it: "The booksellers will not go cordially about the work; there is not that prospect of gain which alone moves the wheels with them." These considerations, and his own sadly infirm condition, gave him little heart to proceed with his work. On Nov. 1st, 1704, he writes to Sloane : " The History of Insects must rest if I continue thus ill, and I see no likelihood of amendment, unless I should outlive this winter, which I have little reason to hope or expect." The following Jan. 7th, he wrote a farewell letter to his same kind friend, and on Wed- nesday the 17th Jan., 1705, about ten in the forenoon, "Death cut the fatal thread of life ;l and deprived the commonwealth of learning of so valuable and worthy a man," as Mr. Dale expresses himself. This was two years before the birth of Linnaeus. And so the Historia Insectorum rested until it was taken in hand by Dr. Derham, F.R.S., Rector of Upminster and Canon of Windsor, the talented author of 'Physico-Theology,' who edited Ray's MSS.; and the book was pub- lished posthumously in 1710, at the command of the Royal Society, consisting of 398 quarto pages. This work must speak lor itself; I have already presented a copy to the Club's library, and when the entomological fauna of the county is under consideration, I may have something further to say as to its contents ; meanwhile, I will not be further wearisome. I have attempted to give an account of its conception as nearly as possible in the words of its author and his friends in letters which are so fortunately preserved to us. Two honoured entomologists have referred to Ray :— Adrian Hardy Haworth says: " To pay due tribute to the virtues and extensive knowledge of this great and meritorious man, or to make deserved mention of his numerous works, is indeed a task beyond the essays of a feeble pen, but, aided by the biographic muse,
