|Copy letter from Robert William Frederick Harrison, to Professor Dr Johannes Bosscha, Haarlem, Holland
|10 April 1897
|With reference to Bosscha's letter of the 5th, Harrison is glad to know the delay in replying to Bosscha's previous letter did not cause him inconvenience.
Regarding the English copy of a letter from Christian Huyghens to his father, quoted in the postscript to Harrison's last letter, Harrison finds it it the one which Bosscha has printed as letter number 1997 in volume seven. Quotes the title of the book to which Bosscha refers; ' Nouvelles Expériences du vide, avec la description des machines qui servent à le faire'.
