| Description | 'I brought your letter of the 8th instant before my Committee and am instructed to thank you for your offer of instruments for exhibition at the Royal Society's Soiree, but to say that space and other considerations prevent them from accepting any but the Ultra Condenser for the observation of Ultra microscopic particles, which seems to have special scientific interest. If you care to exhibit this piece of apparatus I shall be much obliged by your filling up the enclosed form giving particulars for the programme and of your requirements for showing it.' |
