Note 229 — MEMOIR OF THE LIFE OF DAVID RITTENHOUSE; CONTINUED, FROM THE TIME OF HIS SETTLEMENT IN PHILADELPHIA.
Reading edition
Charles Theodore, Duke of Bavaria, who is denominated by Lalande, “an illustrious patron of the sciences.”
It is about fifty years since this prince built an observatory near the gardens of Schwetzingen, two leagues from the city of Manheim; and there Father Christian Mayer pursued his astronomical labours for several years. But about the year 1772, the same prince erected another and a more magnificent edifice (of 108 Rhenish feet in height,) at Manheim, for the same purpose: where Father Mayer made numerous and highly estimable observations; as may be collected from his work, entitled, De novis in Cælo Siderio Phænomenis. Lalande places this observatory in N. Lat. 49° 29′ 15″.
