the Journal, containing abstracts of the various communica- 
tions (128 pages) ; and the Programme and Daily Time Table 
(44 pages). To the latter a daily supplement appeared, 
recording changes in the programme. One of these contained 
the unexpected item : Prof. Tolman on ‘ The Learning of 
Rats. Prof. Katz withdraws.’ There was also a list of the 
members attending. 
Towards the close of the meeting it was possible to purchase 
The Advancement of Science, which contained the President’s 
and the Secretarial addresses, as under : — 
‘ Some Chemical Aspects of Life,’ by Sir Frederick Gowland 
Hopkins ; ‘ Seasonal Weather and its Prediction,’ by Sir 
Gilbert Walker ; ‘ Natural Colouring Matters and their 
Analogues,’ by Prof. R. Robinson ; * A Correlation of 
Structures in the Coalfields of the Midland Province,’ by Prof. 
W. G. Fearnsides ; ‘ The Mechanical View of Life,’ by Dr. 
J. Gray ; ‘ Geography as Mental Equipment,’ by The Rt. 
Hon. Lord Meston ; ‘ The Gold Standard,’ by Prof. J. H. 
Jones ; ‘ Some Experiences in Mechanical Engineering,’ by 
Mr. R. W. Allen ; ‘ What is Tradition? ’ by the Rt. Hon. 
Lord Raglan ; * The Activity of Nerve Cells,’ by Prof. E. D.

of the Traps of Utricularia,’ by Prof. F. E. Lloyd ; * The

At the close of the meeting sums amounting to £jj o were 
voted for scientific research, and it was arranged that future 
meetings of the Association should be held at Aberdeen, 
September 5th to 12th, 1934 ; Norwich in 1935 ; Blackpool 
in 1936 ; and Nottingham in 1937. The unusual course was 
adopted of allowing the various deputations to remain in the 
room while the invitations were received, thus stifling dis- 
cussion. On the proposition of the delegate from the Yorkshire 
Naturalists’ Union, it was unanimously agreed that in future 
the old rule of requesting a deputation to withdraw while the 
matter was being considered, should be resumed. 
In Section A (Mathematics) Dr. Balbage’s address on 
Cremona transformations began with ‘ If Vk is a rational 
K — dimensional locus ’ — so they are not always what they 
seem. In Section B (Chemistry) Dr. D. J. Lloyd referred to 
f The Chemistry of Skin and the problem of the tanner.’ 
In Section C (Geology) the papers, naturally, largely referred 
to Leicestershire. Those of interest to northern readers were 
a discussion on * The shore limes of the Midland Barrier 
during Carboniferous times ’ ; Dr. A. Raistrick referred to 
■ The Microspores of Coal and their use in correlation ; Prof.
