The appendix contains a letter from Indologist and numismatist James Prinsep (1799- 1840), who assisted in creating the tables, to the Calcutta Mint Committee championing the introduction of a single system of coins and measures.

From the recently dispersed library of Erwin Tomash (1921-2012), American engineer recognised for his early pioneering work with computer equipment peripherals.
