Title A photoelectric method of measuring the light of the night sky with studies of the course of variation through the night Type Journal Article
Year (up) 1929 Publication Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character Abbreviated Journal Proc. R. Soc. Lond. A
Volume 124 Issue 794 Pages 395-408
Keywords Instrumentation; Natural Sky Brightness; Airglow
Abstract The investigations already published on the intensity of the night sky have been made by means of visual photometry, using a convenient instrument with a self-contained luminous source of radioactive origin. Nothing could rival this for simplicity and portability; it is always ready and requires no attention. On the other hand visual photometry is not a very satisfactory process even for ordinary light, and with this faint light it is far from giving the desirable degree of accuracy. I have therefore spent much effort in trying to replace it by some photoelectric method of measurement. A satisfactory method has now been evolved, and will be described, together with the results. A preliminary notice of the earlier results was given in a paper written at the request of Prof. S. Chapman, F. R. S., Chairman of the International Committee on Terrestrial and Solar Relationships, the receipt of which was acknowledged by him on June 19, 1928. The relevant passage is:- “Most of the difficulties have been overcome and preliminary observations have been in progress for some months past. I have been able to follow the changes of intensity from hour to hour on clear nights. Some evidence has been found suggesting diurnal periodicity. The observed intensity nearly always increases between nightfall and midnight, beyond which the observations have not usually been carried.”

Title On a night sky of exceptional brightness, and on the distinction between the polar aurora and the night sky Type Journal Article
Year (up) 1931 Publication Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character Abbreviated Journal Proc. R. Soc. Lond. A
Volume 131 Issue 817 Pages 376-381
Keywords Night Sky Brightness; Airglow
Abstract For more than seven years past I have had in progress systematic photometric measurements on the brightness of the night sky as seen through certain colour filters. These filters are designed to isolate separate portions of the spectrum in the red, green, and blue. The green one isolates nearly as possible the light of the green auroral line due to oxygen, but the isolation is very imperfect, and, in fact, the continuous background of the spectrum often contributes more to the transmitted light does the auroral line.

Title Modification of Mammalian Sexual Cycles; Reactions of Ferrets (Putorius vulgaris) of Both Sexes to Electric Light Added After Dark in November and December Type Journal Article
Year (up) 1932 Publication Proceedings of the Royal Society B: Biological Sciences Abbreviated Journal Proceedings of the Royal Society B: Biological Sciences
Volume 110 Issue 767 Pages 322-336
Keywords Animals
Abstract Studies by Rowan (1930 and preceding papers) and Bissonnette (1931, a, b, 1932, a, b, and preceding papers) and Bissonnette and Wadlund (1931) have shown that in juncos, canaries, crows and starlings, at least, among birds, the sexual cycle is conditioned to a great degree by daily light ration. Sexual activity in both males and females can be modified at will by altering the daily light ration with controlled electric lighting from ordinary incandescent bulbs. Gonad changes, controllable in this way, are closely correlated with migrations in juncos and crows, as demonstrated by Rowan (1930, and preceding papers), who, however, maintains that it is the added periods of muscular exercise, rather than the light, as such, that condition these changes, in spite of the fact that it is always the added light he uses, rather than exercise, to get his effects. Bissonnette disagrees, and holds it is the light that is the major factor in conditioning the changes in sexual cycles. It has been found, also, that intensity and colour, or wave-length, as well as daily period of light are factors in conditioning sexual activity in starlings, and the method of increase of light also plays a part (Bissonnette, 1931, b, 1932 ; Bissonnette and Wadlund, 1931).
