Airy integral——The calculation of this integral has been begun. The 
tabular values will be included in the second volume of Bessel functions. 
Confluent hypergeometric functions—11-decimal values of the functions 
M(«, 2,10) and N(«, 2, 10) for «=0-0( —o-.2)—11-0 have been computed by 
Dr. A. J. Thompson, and communicated to Dr. R. Stoneley. These 
functions are defined by

INLAND WATER SURVEY. 
Second Report of Committee appointed to inquire into the position of Inland 
Water Survey in the British Isles and the possible organisation and con- 
trol of such a survey by central authority (Vice-Adml. Sir H. P.

THE Committee records with deep regret the death of Capt. J. G. Withy- 
combe, whose services on the Committee were of great value. 
I. This Committee was appointed after the meeting of the British Associa- 
tion held at York in September 1932, on the recommendations of Section A 
(Mathematical and Physical Sciences), Section E (Geography), and 
Section G (Engineering), and was re-appointed in October 1933, with the 
same terms of reference. 
On page 9 of the Committee’s first report, presented in September 1933, 
its conclusions and recommendations are set out as follows : 
“(i) That, with regard to the first part of the Committee’s reference, the 
position of Inland Water Survey in the British Isles is far from satisfactory, 
and that a systematic survey of the water resources of Great Britain is 
urgently required ; and, 
‘ (ii) That, with regard to the second part of the Committee’s reference, 
the survey, to be of maximum utility, should be conducted by a central 
organisation, preferably under a Government department, independent 
of any interest in the administration, control or use of water. 
“The Committee have given further consideration to steps by which the 
work of the survey could be most expeditiously begun. ‘They have formed
