GEOLOGICAL MAP OF NOTTINGHAM.

the results of all the latest researches into the geology of 
Nottingham, even to the separation of the Keuper Basement 
Beds from the “ Waterstones,” which was decided on by the 
Geological Survey in 1880, though the occurrence of one 
minute strip of these rocks at the foot of Colwick Hill, east 
of Sneinton, was, we understand, accidentally omitted. The 
borough of Nottingham is about five miles in width by about 
seven miles in length, and the work of mapping this large 
area extended over five years. Some parts of the area were 
exceedingly complex and difficult, being much broken up by 
faults and obscured by drift, so that a long iron spud became 
an indispensable companion in the field-work for a long time. 
Mr. Shipman found his friend Mr. Talbot Aveline, F.G.S., 
(who has now retired from the Survey after forty-two years’ 
service) always ready to help him with kind advice or other 
assistance whenever it was needed, and the first of the nine 
sheets into which the original map is divided was surveyed 
under Mr. Aveline’s personal supervision. The physical 
features of the ground are indicated by means of contour 
lines for every thirty feet, and these are the work of 
Mr. Fred. Jackson, C.E., of Nottingham. Altogether, 
geologists who take an interest in the geology of Nottingham 
will feel grateful to Dr. Seaton for enhancing the value of his 
book—itself a model of what a Medical Officer of Health’s 
report should be—-by rendering available this new map of 
Nottingham. It may be mentioned that copies of the book 
are to be had gratis by applying to the Health Department at 
the Municipal Offices, Nottingham, and we certainly advise 
every one interested in the geology of the Midlands to 
endeavour at once to obtain a copy of Mr. Shipman’s very 
admirable map. 
MIDLAND UNION OF NATUBAL HISTORY 
SOCIETIES. 
ANNUAL MEETING AT PETERBOROUGH. 
The members of the Peterborough Natural History and Scientific 
Society have for some time been steadily at work preparing for the 
sixth annual meeting of the confederated scientific societies of the 
Midland Counties. The previous meetings have been held at Birming¬ 
ham, Leicester, Northampton, Cheltenham, Nottingham, and Tam- 
worth. From the considerable local attractions, and from the energy 
always displayed by the local society, the forthcoming meeting at 
Peterborough bids fair to be a most successful one, and we earnestly 
advise the members of the Union not to miss the opportunity of so
