SECTIONAL TRANSACTIONS— A*, B. 337 



Various boundary value problems, as well as equations of higher order 

 and systems of equations are also considered. Green's function is not 

 required at all, and the solutions are given as series of characteristic functions. 

 The Fourier coefficients are determined with the help of infinite systems of 

 non-linear integral equations, which are solved by successive approximations. 

 The uniqueness of the solutions is also established.

Chemistry and the Community : — 



Presidential Address by Prof. J. C. Philip, O.B.E., F.R.S., on 

 The training of the chemist for the service of the community (10.0). 



Mr. M. P. Applebey. — Industry and the profession of chemistry (n.o). 



The chemist's industrial importance is more widely appreciated every 

 year but is yet not fully realised in some industries whose operations are 

 largely chemical. The chemist may be of service in (a) analysis, (b) process 

 control, (c) sales service, (d) research, (e) management. The use of fully 

 trained chemists tends to efficiency, reduction of costs and profitable de- 

 velopment. In regard to (e), a well-organised chemical education compares 

 with other studies as a preparation for all the duties of management. 



Industry depends on strong schools of chemistry, giving sound teaching 

 of fundamentals and inspired by active research. Recruits for the chemical 

 industry should have an honours degree and two or three years' research 

 experience designed to give experimental training and to develop perse- 

 verance and resource. An industrial bias to the research undertaken in 

 training is neither necessary nor desirable. Languages are almost indis- 

 pensable, and men who have shared fully the general activities of their 

 Universities are most useful. 



The obligations of industry to the chemical schools are best discharged 

 by the subsidising of research by research fellowships and by grants for 

 special apparatus and chemicals. Industry should facilitate the active 

 participation of its technical staff in the operations of the publishing societies, 

 and should support the Chemical Council in improving publications, pro- 

 viding library facilities and generally promoting the consolidation of the 

 chemical profession. 



Mr. C. J. T. Cronshaw. — The benign gifts of organic chemistry 

 (11.30). 



The science of chemistry has grown out of the earliest times ; but that 

 part which we call organic chemistry is relatively a modern development. 

 The discovery of mauve by Perkin and his commercial exploitation of his 

 invention showed to the world the possibilities of this branch of chemistry. 

 Upon this discovery Germany gradually erected a great and progressive 

 industry. The uses of colour in a modern civilised world are so varied that 

 it is difficult for a person to-day to look back and realise the meagre uses of 

 colour before 1870.
