30 ON NATURAL HISTORY MUSEUMS. made, more or less systematically by students of natural history, though such collections might never rise to the dignity of a museum. Our great Essex naturalist, John Ray, must surely have possessed a collection. His friend and benefactor, Francis Willughby, we know collected extensively and secured the advantage of Ray's curatorial assistance. In a letter to Martin Lister, dated June 18, 1667, Ray says: "The most part of the winter I spent in reviewing and helping to put in order Mr. Willughby's collection of birds, fishes, shells, stones, and other fossils; seeds, dried plants, coins, etc."37 It is clear therefore that the Willughby collection was of a very comprehensive character. Ray, being a man of restricted means, could hardly indulge in a similar manner, however wide his sympathies may have been ; but that he had some kind of collection is clear, for we are told that "whatever he had preserved relative to any branch of natural history he gave before his death to his neighbour, Mr. Samuel Dale."38 The Ray collection therefore passed to his executor, and the herbarium was presented by him to the Physic Garden at Chelsea, but ultimately found an appropriate resting place in the British Museum. One of the earliest, and still one of the best, natural history museums ever founded by a local society in this country is the museum at Saffron Walden. Soon after the foundation of a Natural History Society in that town, in 1832, it was resolved "that a museum be founded to include specimens in the several departments of natural history, with antiquarian remains and such other articles as might be of general or local interest." The collections were accommodated at first in the house of Mr. Jabez Gibson, who had been mainly instrumental in organizing the society, but in 1834 they were removed to the building specially erected for their reception by Lord Braybrooke. This museum was opened on May 12th, 1835. That the special value of a local collection was recognized at that time is evident from a statement circulated before the building was opened, in which it was said that "the con- centration of Specimens peculiar to the District in which the Museum is established will form a leading feature in its 37 Dr. Derham's Life in Memorials of John Kay.
