ATTENTION is called to a lecture to be given in the chapel of Christ Church, Cambridge, Tuesday evening, February 13, at 7.45, entitled "The United States Government Expedition to Tasmania to observe the Transit of Venus," to be illustrated by views by John Moran, thrown by a powerful stereopticon upon a large canvas screen. The lecturer will be Mr. Leonard Waldo, Assistant at Harvard College Observatory, who accompanied the expedition as Assistant Astronomer. The lecture will be one of importance to those interested in Astronomy, and yet will be so presented as to amuse and instruct a popular audience. Only 400 tickets are to be issued; 200 have already been secured; the remainder will be for sale at the University Bookstore after Wednesday noon next. The proceeds of this entertainment will be for the benefit of Mission work in Cambridge.
