Copy letter from an unknown correspondent, to Mr C Baker, 244 High Holborn In Mr Baker's note of 11 May accompaying the account for the hire of microscopes and lamps, Baker says "3 eye piece missing at 7/6 each'. Please observe that your messenger reported one eyepiece as missing and made a note of it. The '3' refers to the number only, i.e. Number 3, not the amount. A careful search should be made for it and in the meantime, is writing to Professor Sherrington who used the microscopes. 14 May 1898
