THE GEOLOGIST. 



Postscript to Mr. Powrie's Letter on Cephalaspis. — The following 

 postscript to Mr. Powrie's letter on Cephalaspis has just reached us. Ed. Geol. 

 " Reswallie, March 26. Since sending off my short notice of Cephalaspis I 

 have, only yesterday, been able to add to those already noticed another Scottish 

 locality which promises to be moderately rich in remains of this fish ; haying 

 discovered a few imperfect heads in a quarry opened in a wooded hill a little 

 north of Westerton house, near Bridge of Allan, in Perthshire. I would not 

 have thought this deserving of notice had I not in the same place found two 

 heads, undoubtedly of the nearly allied genus Pteraspis, being so far as I am 

 aware the first specimen of this fish recognised in Scotland. I am not sufficiently 

 acquainted with the English specimens of this genus to be able to say whether 

 the two I have found are specifically the same with any of these, or whether 

 they may form an entirely new species."— J. Powrie. 



REVIEWS. 



Old Bones ; or, Notes for Young Naturalists. By B,ev. W. S. Symonds. 

 London: Hardwicke. 1861. 



Old Bones amongst our fore-fathers were of little value indeed, but modern 

 manufactures and chemistry have made them a valuable commodity. Geolo- 

 gists, too, have found a value in Old Bones beyond any ideas of manufacturers 

 or domestics. Prom the old bones of animals that lived in the vastly remote 

 periods of Geological History the paleontologist develops the ideal forms of 

 beings long since extinct and perished from the face of the earth. These he 

 mentally clothes anew with muscles and with flesh, and furnishes us from those 

 dried and stony relics with real accounts of the habits and natures of the 

 beasts and reptiles, fish and birds of lands and seas the eye of man ne'er 

 gazed on. 



W e all know Mr. Symonds' other popular little books, and this will be not 

 less a favourite. All Mr. Symonds does he does well ; but of the illustrations 

 we can only say that they are judiciously selected, and that their execution is 

 as good — or as bad— as in the generality of modem popular geological works, 

 in which the illustrations rarely have any pretensions to truthful or artistic 

 merit. 



The Dublin Quarterly Journal of Science. Edited by the Itev. S. Haughton, 

 M.A, F.R.S. Dublin : McGlashan and Gill. 1861. 



Although our space this month is greatly restricted, and we are still obliged 

 to leave over until future numbers a great quantity of valuable matter in hand, 

 we would not willingly allow the present occasion to pass without a few lines 

 Of congratulation on the appearance of another excellent scientific periodical, 

 the Dublin Quarterly Journal of Science, to which we wish every success, as 

 doubtless will be attained under the able direction of Professor Haughton.
