content: This undated large 8-page booklet is written in German and titled, "Gebrauchsanleitung für Amsler's Planimeter." It describes and depicts nine types of polar planimeter sold by the firm established by Jacob Amsler in Schaffhausen, Switzerland, in 1854. The instructions indicate that Type 1 and Type 2 were distinguished by their materials; Type 1 was made of brass and Type 2 (see MA.318485 and 1984.1071.01) was made of German silver. Similarly, Type 3 (1986.0316.05) was made of brass and Type 4 was made of German silver. The Museum also owns an example of Type 6 (MA.335203). Types 8 and 9 are wheel-and-disc polar planimeters. See 1999.0250.02 for an English translation of the pamphlet.
