Excerpt from Reports on the Administration of the Meteorological Department of India in 1881-82 Apart from questions of Solar Physics, the heating power of the sun's rays at the earth's surface is, however, an important meteorological datum; and for this purpose alone, it would be well worth continuing the present system of actinometric measurement at Calcutta, and this will not be relinquished. During the past year, sunshine recorders, for the purpose of registering the duration of sunshine, have been procured for the principal observatories, and one of these has been in use for some months at Allahabad.
