464 Proceedings of the 



Mr W. A. Jardine, C.E., the engineer to the Edinburgh 

 Paving Board, had been for some time back making a collec- 

 tion of specimens of rocks ; and among those sent him from 

 the parish of Heriot, was a portion of this rock from near 

 Esperston, which he gave to Mr Forrest for examination, and 

 which was evidently grey granite. Mr Jardine and Mr 

 Forrest brought the matter under the consideration of the 

 Paving Board, and a deputation, including these gentlemen, 

 visited the locality. It appeared that Mr Pringle, Garvald, 

 in excavating for materials to build stone dykes, had recently 

 exposed the rock near Carcant Nick, on the road from Fushie 

 Bridge to Innerleithen, where it seems to form the principal 

 part of the hill of Broadlaw, stated in the Ordnance Survey 

 map as 1414 feet in height ; the strata, described as of grey- 

 wacke, being exposed on its side in nearly a vertical posi- 

 tion. Dr Smith observed what appeared to be small particles 

 of the White Iron Pyrites disseminated through one of the 

 specimens of this granite. Should this occur generally, from 

 the well-known easily decomposing property of this Pyrites 

 under the action of the weather, he feared the beauty, if not 

 the durability, of this granite might possibly be affected.] 



VII. Notes of some Experiments recently made on the Preservation of 

 certain Marine Radiata. (Numerous preserved specimens were ex- 

 hibited.) By James B. Davies, Esq., Assistant Conservator, University 

 Museum. 



Though the experiments, the results of which I am about 

 partially to lay before you, were commenced fully two years 

 ago, they are yet so far from being completed, that I can only 

 plead as my excuse for calling your attention to them just 

 now, the fact that they may be of some service to a few of 

 you during the recess, and may perhaps secure me the co- 

 operation of such of the members of the Royal Physical 

 Society as devote themselves to Marine Zoology. 



At present I desire to restrict myself to the Sub-kingdom 

 Radiata, not on account of any peculiar regard for that 

 group, but simply because many of the members of it are so 

 imperfectly represented in Museums, public as well as private, 

 on account of the difficulty of preserving the specimens with
