AD VERTISEMENTS. 



OPINIONS OF THE SCIENTIFIC PRESS. 



"SCIENCE GOSSIP," December 1st, 1894. 



" The first part of this long-expected work is at last before us, and we 

 may candidly say it exceeds our expectations. Well considered, well 

 arranged, well illustrated, and well produced, I'art I. creates the impression 

 that we have at last in view a standard work on this popular group of easily 

 studied animals. It bids fair to be, for a long time to come, much the best 

 and most complete work on the subject. The illustrations are excellent, 

 specially the coloured plate ... If the high character of this first part is 

 as well maintained to the end of the work, and of this there is no reason for 

 doubt, we shall have not only an useful, but a very handsome book indeed." 



"THE ZOOLOGIST," February, 1896. 



"This . . . new work on British mollusca . . . from the thorough 

 mode of treatment adopted by the author and the excellent and numerous 

 illustrations given, promises to eclipse all previous text-books on the subject, 

 as far as Great Britain is concerned. The introductory matter . . . being 

 admirably illustrated by explanatory figures . . . The typography is 

 excellent, and the illustrations, which are numerous, are far superior to any 

 figures of mollusca and their shells w hich we have seen . . . Indeed, so 

 far as it is possible to represent forms and markings without the aid of color, 

 we do not think the shells could be more correctly represented." 



"THE NAUTILUS," June, 1895. 



" The first part well sustains the expectations excited by the prospectus 

 . . . for it makes perfectly clear to the beginner in Conchology the whole 

 jargon of descriptive terms, and by a well chosen illustration fixes it in his 

 mind . . . Excellent illustrations are scattered freely throughout the 

 text, illustrating at every point the statements made or peculiarities men- 

 tioned ; and this is a new departure in Conchological treatises which can 

 hardly be too w^armly commended. The species will be illustrated with 

 coloured plates, of which one accompanies this part. It is a really superb 

 piece of colour printing." 



OPINIONS UPON THE ILLUSTRATIONS. 



"I have examined your very effective plate, which strikes me as really fine 

 work; especially in the drawing. Liviax viaximus is fairly gliding off the 

 plate, and a very happy likeness." R. D. Darbishire, B.A., F.G.S., etc. 



" I think it excellent. What struck me as most praiseworthy is the evident 

 minute faithfulness with which the markings had been copied ; as works of 

 art I think nothing more could be desired." L. E. Adams, B.A., etc. 



"It is admirable and almost beyond criticism . . . The Aspersas, 

 indeed everything, are wonderfully good and far beyond anything in English 

 works." Chas. Ashford. 



" I think it [the plate of figures] is excellent in every way, and the more 

 I inspect the more I admire it." J. Cosmo Melvill, M.A., F.L.S., etc. 



"I think your figures are admirable, free from that exaggeration of colour 

 which so often spoils the best drawn figures." 



Rev. A. H. Cooke, M.A., F.L.S.,etc.
