and has not hesitated to place near the genus Didelphis. 
Three specimens of the same bone were already known; the 
fourth which has now been presented to this Museum, was 
contained in a collection made for Sir Christopher Sykes by 
Mr. Platt, of Oxfordshire, more than forty years ago. It was 
found in that collection by Mr. Phillips, who, having declined 
the offer of it to himself, afterwards accepted the proposal of 
the liberal donor to place it in the Yorkshire Museum. 
A zealous patroness of geological science, Miss Benett, 
has honoured the Society with an extensive donation of fossils 
belonging to the chalk and inferior beds, and including speci¬ 
mens of the alcyonites of Wiltshire, accompanied by a copy of 
the unpublished work in which they are figured. From Mr. 
Mantell there has been received a selection of the fossils of the 
Tilgate beds and of the chalk of Sussex, augmented by a 
contribution from the same county by Archdeacon Croft,—from 
the President of the Geological Society , 1 specimens of the insects 
preserved in the lacustrine deposits of Aix, in Provence,—from 
Dr. Buckland, fossils and casts of bones illustrative of some of 
his discoveries,—from Mr. Chantrey, a cast taken by him from 
the magnificent specimen of Plesiosaurus, in the Duke of Buck¬ 
ingham’s collection,—from Mr. Henwood, a series of specimens 
illustrative of the rocks and mineral veins of Cornwall,—from 
Mr. Grimston, the fossil shells of the most ancient depository 
of organic remains in Britain, the slate of Snowdon,—from 
Mr. Lewis, those of the transition slate of Herefordshire; 
and from Mr. Loscombe, a miscellaneous collection which has 
supplied many desiderata in the geological catalogue. 
A few additions have been made, illustrative of interesting 
facts in the Geology of Yorkshire. To the Curator of the 
Philosophical Society of Leeds, 2 the Museum is indebted for
