“ The site at Port Louis was unsuitable for a meteorological observatory, and with the support of Sir E. Sabine he was able to obtain the erection of a new station at Pamplemousses—a site unhappily marshy and fever-stricken. Here the foundation stone of the Royal Alfred Observatory was laid in 1870 by the Duke of Edinburgh. The principal work of the observatory was as before the study of the movement of storms, but from 1880 photographs of the solar surface have been taken daily to supplement the series made at Greenwich and Dehra Dun for a continuous record of the number of spots on the sun. ”
