84 HISTORY OF THE [1840-50 veneration to this Society as long as it preserves its own existence," as the Council remark in adverting to the gift (1846 February). Later, Baily's sister presented the bust which stands in our hall, " a faithful and charming reproduction " Herschel says of it, " of features we have so often seen in this place, animated with the pure love of science and with deep interest in the welfare of this Society." Assistant Secretaries. J. Hartnup, who has been mentioned above, was one of three men, each of considerable ability, who held during the decade the office of Assistant Secretary, upon which so much of the amenity and even effectiveness of the Society depends.

The Monthly Notices were a compilation by the Secretaries from such material as was available, and seldom comprised more than an abstract of an author's com- munication. In 1847 the system was reformed. Thereafter, Monthly Notices became more full and more denned in form. Their contents were to be considered a substantive record of the proceed- ings of the Society, a portion of its Memoirs ; in it alone were printed such observations or papers as had an immediate interest or were in a transition state of reduction. Sheepshanks undertook the responsible work of editing them. He inserted an explanatory note prefacing volume 8.
