In 1869 he was elected a fellow of the royal society, and during that and the following year he announced to it many important discoveries in solar physics. He was the chief of the eclipse expedition sent to Sicily by the English government in 1870, and in 1871 he was appointed Rede lecturer in the university of Cambridge. He is widely known as a lecturer on science, and his contributions to periodicals on scientific subjects are very numerous.
