The Bradford Public Free Libraries are to be congratulated on the 

 production of a ' Class List of Books in the Reference Library on Natural 

 Science.' The various subjects are classified, and, in addition, the list con- 

 tains an index of subjects and an index of authors. This is the fourth of 

 a series of Class Lists, and the example set by Bradford might well be 

 followed by the Library Committees at other places.

The summer issue of the ' Notts and Derbyshire Naturalists' Quarterly' 

 (formerly the * Derbyshire Naturalists' Quarterly') (24 pp., 6d.) is to hand. 

 It contains papers on some pre-historic remains in Cornwall, ' The Ancestors 

 of the Horse,' ' How to Choose a Microscope,' etc., and also reprints articles 

 from the Zoologist and other sources. It is a pity that more matter does 

 not appear relating to the two counties named on the title of the publication, 

 and surely a few local notes suitable for publication might have been found 

 to fill the last page, which is left blank.

Messrs. W. Lower Carter and W\ Cash are to be congratulated on the 

 appearance of the ' Proceedings of the Yorkshire Geolog^ical and Poly- 

 technic Society for 1902,' which is largely devoted to papers bearing on the 

 Carboniferous rocks. Mr. Robert Kidston's ' second paper,' dealing with 

 'The Flora of the Carboniferous Period,' should be particularly serviceable 

 to those interested in the Flora of the countv at that remote time, and the 

 numerous beautiful plates will doubtless be appreciated bv collectois of coal- 

 measure fossils. A specimen of Sigillaria on Plate LIX. shows some of the 

 difficulties in identifying: species : — ' The u])per portion of this specimen shows 

 the Sigillai-ia Brardii Brongt. . . . and the lower part Sigillaria denudata 

 Goppert ... in organic union. The intermediate portion is the Sigillaria 

 rhoiiiboidea Brongt. Quite a large number of the specimens figured are 

 Yorkshire specimens, collected by Mr. W. Hemingwav. Dr. Wheelton 

 Hind furnishes an elaborate description of the Carboniferous Rocks of the 

 Pennine system, with lists of fossils, comparative tables, etc.; and Mr. E. D. 

 W'ellburn follows with notes ' On the Fish Fauna of the Pendleside Lime- 

 stones,' and 'On the Genus Coelacanthus as found in the Yorkshire Coal 

 Measures,' the latter being accompanied bv a restoration of Coelacanthus. 

 Other papers are ' Ingleborough, Part II.,' by Prof. T. McKeimv Hughes ; 

 'The Circulation of Salt and its bearing on Geological Problems,' by 

 W. Ackroyd ; 'A Striated Surface near Sandsend,' by Mr. J. W. Stather ; 

 and 'Notes on the Igneous Rocks of the English Lake District,' b)- Mr. Alt".
