appears, witli any of the great military roads throngh the 
county. In the adjoining ground, a very rare Eoman coin 
was found, a first brass of Manlia Scantilla, the Wife of the 
Emperor Didius Julianus, who enjoyed during three months of 
the year a. d. 193, the imperial dignity which he had pur¬ 
chased Eom the Praetorian guards by a bidding of 25,000 
sesterces per man. 
The Ethnographical collection has been emiched with a 
series of casts from objects sculptured in Eeindeer horn, found 
in the Caves of the Dordogne, France. These interesting fac¬ 
similes were presented to the Society by the Trustees of the 
Cliristy collection, through the kind intervention of H. Wood¬ 
ward, Esq., of the British Museum. A valuable collection of 
objects (dresses, weapons, baskets, calabashes, &c.,) from the 
west coast of Africa was also secimed for the Museum by ]3iir- 
chase in the early part of the year. 
The Gteological collection is again indebted to J. F. Walker, 
Esq., B. A., &c., for an interesting series of fossils from the 
neighbourhood of Cambridge. These are illustrative of a newly 
discovered deposit of the age of the Lower Grreensand at Dpware, 
on the Cam, the general characters of which were described by 
Mr. Walker, in a paper read before this Society and published 
in the Geological Magazine. Together with these, Mr. Walker 
also presented the Museum with a small series of fossils from 
the nearly contemporaneous deposit at Farringdon in Berkshire, 
hitherto unrepresented in our collection. 
To the Mineralogical collection, the Reverend D. R. 
Roundell has presented a considerable number of fine specimens, 
including many interesting cut and polished agates, gems, &c., 
and Robert Denison, Esq., a large specimen of Fluor Spar with 
Pearl Spar from Cumberland. 
Among the contributions to the Zoological collections there 
are only two which call for specieJ notice, namely, an interestiug 
collection of Bird-skins from the Nile, presented by T. Codfi’ey 
Hatfeild, Esq., of Thorp Ai’ch, and a magnificent specimen of 
Cidaris papillosa^ one of the rarest of the British Echinodermata, 
presented by John Leckenby, Esq., F. G. S., of Scarborough. 
The latter was accompanied by some examples of scarce Polyzoa,
