6¢ ( X EOLOGY FOR ALL” is a very attractive title, and we wish 
that such a work may succeed, for no little credit would 
attach to the man who could enable the general public to master the 
alphabet of geology. Outside a limited circle even the well-educated 
continue in a complete fog as to things which are simple in them- 
selves, and ought to be understanded of the people without difficulty. 
How far the book in question fulfils this want is a point on which 
opinions may differ. It is dedicated to the memory of Prof. Morris, 
and a very good likeness of that best of all geological teachers faces 
the title-page. Not the least valuable part of this little work consists 
of the Preface and Introduction, which are full of inducements to 
pursue the study of geology. When we come to the dry bones of 
the subject, then a text-book is a text-book, whether it be long or 
short. On the whole, the author places before his readers a consider- 
able amount of matter of a useful kind within the space allotted to 
him, though he makes a slip here and there. As, for instance, at 
page 41, where he is rash enough to give a formula for orthoclase 
which would yield less than 24 per cent. of silica in a mineral con- 
taining over 64 per cent. He is especially strong in dealing with 
physical features, and his great experience in connection with geolo- 
gical excursions renders this part of his subject comparatively easy 
to him. We sincerely trust that his ability and enthusiasm may gain 
many converts to the good cause. W. H. H.

| eee though nominally only a fresh issue, is in fact a new edition 
of the volume which first appeared in 1886. It is printed in 
a handier form, has undergone revision, and the subject-matter has 
been re-arranged. 
The work ‘does not seek to be a book of instruction to those in 
charge of Free Libraries,” but is intended to further the extension of 
the Free Library movement and to aid those who are seeking to 
secure the adoption of the Libraries’ Act in their district by furnish- 
ing advice how to initiate and how to carry out the undertaking. 
A chapter is devoted to ‘‘Museums and Art Galleries,”—and 
another to “ Science and Art ”—*“ in connection with Free Libraries ;”’ 
but though “Commercial Museums” and ‘Technical Education ” 
have each their paragraphs, minerals and geological collections have
