content: This undated large 4-page booklet is titled, "Instructions for Using Amsler's Planimeters." It describes and depicts nine types of polar planimeter sold by the firm established by Jacob Amsler in Schaffhausen, Switzerland, in 1854, but in less detail than the German-language pamphlet, 1986.0316.09. As in that pamphlet, the arms of Types 1 and 2 are equal in length, even though some surviving examples and advertisements such as Dietzgen's 1904 and 1926 catalogs have a shorter tracer arm. Dietzgen also sold Types 4 and 6 in 1904 and Type 4 in 1926.
