Typewritten letter from B. Melvill Jones to Frederick Lanchester, 10 January 1939
10 January 1939
Thanks Lanchester for letter of 8 January (LAN/1/11/10). Thinks this a bad time to enter into a discussion on an alternative system of dynamical units and certainly not in public. Says he uses in his Department the pound-poundal system, but if entirely free would use Lanchester’s bête noire the slug-pound system. Argues case for his preference and fails to see why “you should allot to yourself a superior degree of fundamentality”. Follows this by further discussion of the topic.
