OPINIONS: OF THE SCIENTIFIC PRESS. 
“SCIENCE GOSSIP,” December ist, 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, Part 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 . . . Ifthe 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, 1895. 
“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 which 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 
f 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 warmly 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. 
“IT have examined your very effective plate, which strikes me as really 
fine work, especially in the drawing. Limax maximus is fairly gliding off 
the plate, and a very happy likeness.” R. D. DARBISHIRE, B.A., F.G.S., etc. 
“*T think it excellent. What struck me as most praiseworthy is the evi- 
dent minute faithfulness with which the markings had been copied; as works 
of art I think nothing more could be desired.” L. E. Apams, B.A., etc. 
“It is admirable and almost beyond criticism . . . The Aspersas, 
indeed everything are wonderfully good and far beyond anything in English 
works.” Cuas. ASHFORD. 
‘*T 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.”
