content: Peters, Julius
notes: label: Description
content: This half-shadow polariscope is marked "Julius Peters - Berlin NW 21" and "No. 696” and “NBS 3985." It has a Lippich polarizer, double quartz compensation, trestle stand, and thermometer. The National Bureau of Standards transferred it to the Smithsonian in 1960. The Bureau was established in 1901 and given responsibility for standardizing the saccharimeters and other apparatus that customs agents used to assess the saccharine quality of sugar coming into the United States.
label: Description
content: Julius Peters displayed instruments of this sort at the World’s Fair in St. Louis in 1904, and Bausch & Lomb imported them into the United States. G. W. Rolfe, an instructor in sugar analysis at M.I.T., described the special features: the mounting was designed for stability and rigidity, the wedges of the analyzer were enclosed in a dust-proof box, the pinion that moved the wedges was lengthened so that the observer could move it with his hand resting on the table, and the scales were made of an alloy named “nickelin” that was not affected by moisture and but little affected by temperature.
