|Copy letter from Robert William Frederick Harrison, to Professor John Perry, Fellow of the Royal Society
|23 June 1908
|Harrison's difficulty in responding to Perry's request for a Sir Michael Foster portrait for Imperial College, is that there are so few left. But he shall ask the Treasurer of the fund to print some more presentation. Whether this can be extended to an additional copy for a particular department Harrison is not so sure, as the professor in charge was not one of the subscribers to the portrait.
