This manuscript contains a treatise on astronomy (fol.1r), written by a student of mathematician Gottfried Wilhelm Leibnitz (1646-1716), with additional notes on solar eclipses (fol. 30v), notes on intercalation, and a list of fairs in German towns (fol.41r). The treatise was completed in 1730, and Neubauer concluded that the present manuscript is an autograph (no. 134, p. 38). This has been called into question, but it varies in a number of places from the first edition (Amsterdam, 1756) and, like a handful of other manuscripts (Oxford, Mich. 498 & 603, and MS Moscow, Guenzburg 1743), it is probably an important early draft, perhaps in the hand of an amanuensis.
