Description | Harrison does not anticipate any objection to Mr Kerr using a reproduction of the block in Philosophical Transactions of the Royal Society for his article in Encyclopaedia Britannica, and though formal sanction will be sought from the Council, he may anticipate permission being granted. Providing the illustration is a half tone block, an electro of it can be obtained at a small cost, and Harrison will send in an order if this is the case. |
