April 19 Thursday In London, England Sam wrote an aphorism to Miss Bessie S. Bowker, Peckham, S.E., London: “There isn’t a Parallel of Latitude but thinks it would have been the Equator if it had had its rights. / Truly Yours / Mark Twain / Miss Bessie S. Bowker. / Apl. 19, 1900” [MTP].
Jonas Henrick Kellgren Osteopath, billed £24.3.0 for visits to Apr. 19 for Jean’s treatments [1900 Financial file MTP]. Note: the good doctor’s bills don’t always appear to be consecutive and are not usually itemized beyond amounts and last date (compare this amount and date with the Apr. 14 bill).
