YORKSHIRE NATURALISTS' UNION. 
proved most satisfactory. Not only has the firm kept to its 
arrangement and produced a magazine equal in every way, as 
regards the number of pages and illustrations, to the 1905 volume, 
but they have even exceeded their undertaking in a most generous 
manner. This year the volume contains 30 plates, and the number 
of pages and illustrations is also far in excess of last year's 
number. In March, July, and September additional sheets were 
included in the magazine without additional expense to the 
members of the Union or to the subscribers. In connection with 
the special British Association number, issued in September, the 
firm printed 32 pages extra in the magazine, and reproduced 
portraits of some of the Presidents. This number can be safely 
said to contain the scientific results of the British Association so 
far as they affect the northern counties. 
From a scientific point of view, the Naturalist " for 1906 
can be safely said to have fully maintained, if not exceeded, the 
value it has had in recent years. Whilst most of the former 
contributors still favour the journal with notes, we welcome in our 
1906 volume the appearance of several contributions by other well 
known authorities. Palasontology has been particularly well repre- 
sented, and largely in connection with the work upon the Yorkshire 
Carboniferous rocks, papers have appeared from the pens of 
Messrs. Cash, Cosmo Johns, Wheelton Hind, Walcot Gibson, 
Weiss, and Miss Stopes. The rocks of the Cretaceous system 
have also received unusual attention, and upon these, notes have 
appeared by Messrs. C. Davies Sherborn, W. Hill, J. W. Stather, 
H. C. Drake, C. G. Danford, A. Burnet, and G. C. Crick. Impor- 
tant notes referring to other systems, and to Glacial Geology, have 
also been published. The botanists have been well catered for, 
and in the forthcoming volume will be treated even more gene- 
rously. The zoologists have been favoured by Mr. A. Whitaker's 
most valuable notes on the habits of bats ; and more ornitho- 
logical notes than usual have appeared, though with this branch, 
as with entomology, an improvement might be made. By means 
of the ''Notes and Comments," and "Northern News," columns, 
the readers of the Naturalist" have been kept well and promptly 
informed of papers and notes likely to interest them, which have 
appeared elsewhere ; these items, to some extent, taking the place 
of the bibliographies formerly appearing in the journal. The 
excursions of the Yorkshire Naturalists' Union have been fully 
reported in the journal, and in many cases the reports were 
illustrated. A new feature — and a useful one — is the series of 
** Prominent Yorkshire Workers" which has been started, the 
notice of Dr. H. C. Sorby (with portrait and list of monographs 
and papers) being admirable. Dr. Woodhead's absence abroad, 
for most of the year, has thrown the work in connection with the 
1906 volume very largely upon the shoulders of Mr. Sheppard.
