Excerpt from Prize Essay on the Distribution of the Moon's Heat and Its Variation With the Phase The bolometer used in this research exposes a sensitive surface of about 19 sq. Mm. It is covered by a diaphragm of white card pierced by a central circular aperture, cm. In diameter, which permits a more accurate setting, especially in the condition of tangency to the moon's limb. The part of the image of the moon selected for measurement is brought to coincide with this aperture by the adjusting cords of the siderostat, all the coarser details of the surrounding lunar surface being readily seen on the white card. The adjustment having been made, the clock-work of the siderostat is trusted to keep the image fixed within small limits which will be described further on.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
