This is accentuated in these days by the exigencies of aeroplanes suffering from loss of the power of one engine—a present conditions, which arise not only from the extreme shortage problem of the highest importance and some complexity.

This comes particularly hard on AIRCRAFT ENGINEERING same subject treated on completely non-mathematical lines which which, if it is to fulfil its function of disseminating knowledge on a appears in this issue, we decided to substitute his article for the highly abstruse technical subject, must publish articles involving a Dutch paper, contenting ourselves with a reference to the latter (to high proportion of formulae—since the lessons they are trying to which we drew M R YATES'S attention) and a short summary appear convey can be expressed in no other way. ing at the end of the article. We desire to offer our apologies to our Dutch friends for treating them in this cavalier fashion, which we A Cumulative Effect hope they will understand in view of what we have written earlier. Unfortunately at the present time the setting of these mathematical formulae is a very serious problem as there is a strictly limited number An Example for Others of compositors capable of undertaking this highly skilled work, and The article by M R YATES is, we venture to assert, a brilliant ex it is also a long and laborious process which has to be done by hand ample of the possibilities in treating a complicated technical subject and cannot be operated by machine.

The inevitable consequence of this is the point of view we touched on in our first paragraph, of having so that articles of this character have now to be very carefully 'rationed' wide an appeal that we can scarcely visualize any of our readers who and spread out over the issues.

A New Contact We also welcome MR YATES'S paper because, although he is A Note for Contributors already known as the author of the article on 'Carpets and Lattices' We are opening our heart on these matters in this way so that in our January, 1946, issue, he is the first active member of the teaching staff of the COLLEGE OF AERONAUTICS to send an original authors may understand the position and readers may also appre contribution to AIRCRAFT ENGINEERING—albeit several of his present ciate it and forgive the fact that in some instances subjects are dealt colleagues have, if we may so put it, served their apprenticeship in with which might well have been expected to be covered in these columns much sooner.
