Monzert, Leonard. Monzert’s Practical Distiller. New York: Fitzgerald Publishing Corporation, n.d. Copyright 1889 by Dick & Fitzgerald. Supplied 168-page scan.
The text sets out a 100-proof/50-percent convention, distinguishes volume from weight and addresses hydrometer temperature correction and mixture contraction. It supplies Tralles and Beaume tables, dilution and strengthening examples, and boiling temperatures for saturated solutions.

Checked against supplied scan. Citation supports an attributed account of the source, not independent validation. Visual checks confirm printed errors as well as OCR problems: p149 includes 93.19 weight percent at 88 volume percent and p155 prints an invalid strengthening calculation, including 175 divided by15 shown as11 3/5. P153's generalized dilution wording subtracts100 regardless of starting quantity. Tables are preserved as historical artifacts, not imported into calculators. Cell-by-cell calibration against modern standards was not performed.
