THE ESSEX FIELD CLUB. 149 Boyles Court is a comparatively modern mansion with recent additions, pleasantly situated, with charming views across the valley of the Weald Brook to Weald Park, Rochetts, and Dagnams. Here they were most cordially received by Mr. and Mrs. Lescher, who had kindly provided light refreshments, which were very welcome ; and claret cup, tea, fruit, etc., were well discussed, before the more scientific work was commenced.

Passing up into the Museum, where the collection is now very nicely dis- played, an inspection of the birds was made, and then Mr. J. E, Harting, F.L.S., editor of the "Zoologist," gave a short account of the late Mr. Hoy, and, walking round the cases, pointed out the more interesting specimens, making observations upon them and their habits. Mr. J. D. Hoy, by whom this very fine and interesting collection of birds was formed, was born in 1797, and resided at Stoke Priory, Stoke-by-Nayland, which (though close to the Essex border) is in Suffolk. He was a first-rate shot and a skilled bird-preserver. Dr. Bree has declared that "as a working naturalist he was almost unequalled in his day in this country." He collected chiefly upon the coasts of Norfolk and Suffolk, and his collection therefore contains few or no Essex specimens of importance. During the latter part of his life he paid many visits to Holland and Germany. It was during one of these expeditions, when collecting mainly among swamps and marshes, that he laid the foundation of the illness of which, at the early age of forty-two, he died on October 15th, 1839. He published little beyond a few notes in various natural history periodicals, but Hewitson, Yarrell, and other writers in the early part of the century received much valuable assistance from him. On his death his collection passed into the possession of his sister, the late Mrs. Lescher, of Boyles Court, mother of Mr. J. F. Lescher. It is contained in 269 separate cases, which were in the entrance hall, but have been re-arranged this year in the museum on the first floor, open- ing into the conservatory. Although very few of the specimens are local, many of them are of consider- able historic interest. The gem of the collection is, of course, the Great Auk, one of the seventy-nine specimens known to exist, of which only twenty-two are
