244 Notes. and Comments. 
HISTORY OF GEOLOGY. 
Mr. Horace B. Woodward’s recent History of the Geolo- 
gical Society of London perhaps clearly indicates that he was 
the most likely person to write a concise ‘ History of Geology,’ 
and an admirable volume with this title has been published for 
the Rationalist Press Association by Messrs. Watts & Co., 
London, for the low price of one shilling. A student, or would- 
be student of geology, will find this book most useful. It 
contains some quaint information in reference to the early 
theories regarding the history of the earth. There are also 
interesting biographical notices of some of the pioneers of the 
science. Amongst these we do not notice the name of Thomas 
Hawkins, who worked amongst the saurians in the thirties ; 
though Mary Anning is mentioned; nor Frederick Dixon, 
who published good work on the ‘ Cretaceous and Tertiaries of 
Sussex’ in the ’fifties. 
GEOLOGY : CHAPTERS ON EARTH HISTORY. 
Messrs. Milner & Co. (Halifax and London) have issued a 
further volume in their remarkable ‘ Twentieth Century 
Science Series.’ It is by Mr. G. Hickling, of the Manchester 
University, and has eight chapters, dealing with ‘ The Origin 
of the Earth,’ ‘ Volcanoes and Earthquakes,’ ‘The Solid 
Rocks,’ ‘Earth Sculpture,’ ‘The Sea Floor,’ ‘ Mountain 
Building,’ ‘ The Physical History of Britain,’ and the ‘ History 
of Life on the Earth.’ There are several excellent illustrations, 
and these, together with the 136 pages, and stout cloth cover, 
make an excellent shilling’s worth. This, together with Mr. 
W oodward’s volume just referred to, would give any intelligent 
person a very good start in geology. 
‘ BUTTERFLIES AND HOW TO IDENTIFY THEM’ 
is the title of a neat little well illustrated volume published by 
C. H. Kelly, London (64 pp., 1/-), and written by the Rev. 
S. N. Sedgwick. It includes chapters containing useful general 
information in reference to the butterflies ; numerous illustra- 
tions (some coloured) of eggs, larve, pupe, and the male and 
female butterflies. Lists of the species are given, with their 
food-plants, period visible, locality, etc., and then follows a 
list of all the British species, classified under the heads of ‘ No.,’ 
‘Name, ‘Imago,’ ‘ Larva,’ ‘ Pupa,’ ‘ Food-plant,’ and * Lo- 
cality.. There are some blank leaves at the end for notes. 
THE BRITISH MUSEUM (NATURAL HISTORY). 
At the recent meeting of the Yorkshire Naturalists’ Union 
at Castleton, the following resolution was unanimously passed, 
on the proposition of Mr. G. T. Porritt, seconded by Mr. T. 
Sheppard :— That the Yorkshire Naturalists’ Union strongly
