FIRST EDITION IN ENGLISH.  Laplace's important work on astronomy was translated by J. Pond, who notes: "The reader will find the angular measures and measures of time used by the author reduced in the margin to the sexigesimal system adopted in this country; this was thought better than altering the text o an original work of such importance" (Note, p.vi). The note is followed by a table of French measures on the facing page. A FINE COPY IN ORIGINAL BOARDS.
