Fisher Refractometer Directions for Use

The Leaflet below was issued by Fisher Scientific c. 1950. It is reproduced with permission of Fisher Scientific


The instructions reproduced here appear to be hand typed on 8 1/2 x 11 inch paper and folded to fit a standard letter envelope. They are apparently original to the Fisher refractometer at Humboldt State University. The first page is reproduced in color and in the folder in which the instructions are contained.
