orii3:in. I also noted some flint knives, and some other thin cutting implements 

 with regular serrated edges, wliich I took to be prototypes of saAvs. In addi- 

 tion to these ante-celtic remains, their are several instances derived from the 

 contents of barrows of flint " urchins" being treasured up as sling-stones. I 

 beg to suggest an examination of the local museiuns where such remains may 

 be expected to occur, and a reference to the locality where found, if given. In 

 the nmseum of Le Puy, I saw one of the flint tools which M. Aymard subse- 

 quently told me came from Perigueux, where a manufactory of them had evi- 

 dently been discovered. — S. R. Pattison. 



The Discovekjer of the Pteraspis Remains in the Lotvee, Ludlow Bed 

 (" Geologist," vol. iii., p. 26). — AVe have received a communication from Mr. 

 J. E. Lee, of Caerleon, inclosing certain letters from Mr. Lightbody to himself, 

 in relation to the discovery of these interestiug fish-remains. It is manifestly 

 impossible for us to know the minutiae of every geological transaction, but it 

 is always within our province, and certainly agreeable to ourselves to become 

 the means of correcting any of those accidental errors which will occasionally 

 occur. In the case of these Pteraspis remains, it appears Mr. Salter, in the 

 Annals and Magazine of Natural History for Jidy, 1859, has doubtless most 

 unintentionally committed the error of attributing their diseoverv'to j\Ir. Liglit- 

 body, who foi-warded them to Mr. Salter for examination and description, 

 instead of to Mr. Lee, who really found tiiem in the " starfish cpiarry" at Lcint- 

 wardinc, when collecting fossils there in company with ^Mr. Liglitbody. Errors 

 of this kind are much to be rej^retted, as the chief reward of the labours of 

 provincid geologists is in their due appreciation and acknowledgement by the 

 special authorities to whom they communicate, lend, and often give their most 

 prized treasures, and in the present ease it seems to be particularly unfortunate, 

 as the specimen lias been liberally presented by Mr. Lee to the Jermyu-street 

 Museum, and duly acknowledged by Sir Roderick Murcliison to him.

REVIEW. 



Geology in the Garden. By Henry Eley, M.A. London : BeU and Daldy. 



" Geology in the Garden " is a pleasing idea ; it suggests at once the simple 

 plan and story of the book, but we scarcely thought when we opened it the 

 garden would have given so wide a range — so much scope of subject available 

 for so much instruction as Mr. Eley has made it convey. 



Walking round his garden, one sees two prominent subjects of inquiry — the 

 gravel of the walks, and the soil of the beds. The gravel derived from tho 

 flints of the chalk contains microscopic and other cretaceous fossils, which of 

 course are fully described. Eor the most part they consist of Eoraminifera ; 

 and Mr. Eley's original observations and remarks upon that wonderfully diver- 

 sified class of simple rhizopods do him high credit for acuteness of investiga- 

 tion and perspecuitj of explanation. The other topic — the soU of the beds — is 

 handled with considerable skiU, and attention is admirably directed to the 

 powerful influences exerted by earthworms in assisting the waste by rainfall 

 and other denuding operations. One extract on this topic will bring a valuable 

 consideration home to many of our readers : — ^
