The typed page instructions were found under an instrument in HSU's physical chemistry lab. They probably accompanied our AB-2 analytical balance in the 1950's (though some notes on the first page refer to our SG-1 specific gravity balance). The sash page was kept in a Christian Becker balance folder in our analytical chemistry service room. The pages are in order going from left to right. Clicking on the icons will bring up a full-size image.
The colors reflect the age-coloring of the paper in these documents.
