to secure a portion of the collection ; and thus, for 

 the sum of £103, a most valuable series of specimens, 

 illustrative of the London Clay of Hampshire and the 

 Isle of Wight; the Upper and Lower Chalk, Chalk 

 Marl, and Upper Green Sand of Wiltshire ; the Lower 

 Green Sand of Farringdon, Wealdon Formation; Port- 

 land Beds of Tisbury ; Oxford Clay of Weymouth ; 

 Lias of Lyme Regis; and Mountain Limestone of 

 Frome, were selected, and with especial reference, as 

 much as practicable, to the diagnostic Fossils of each 

 system. 



By this timely and munificent aid of the Members 

 whose names are recorded, the Geological department 

 has been enriched by many specimens of great beauty, 

 belonging to different formations of the secondary and 

 tertiary periods, of which the Museum was heretofore 

 very deficient. 



The Council have also great pleasure in report- 

 ing that in the Middle Paleozoic series, of which the 

 Museum at present possesses not a single example of 

 the organic remains of this early period, the Society 

 have the promise of a collection of those singular 

 forms of Fishes peculiar to the Old Red Sandstone, 

 from Caithness, &c., from the President, Rev. William 

 Sinclair, A.M., which they hope will be incorporated 

 with the collection before next Session, and thus 

 another and most important Geological epoch will be 

 illustrated.
