Description | 'The National Physical Laboratory have received permission to reprint the paper on "The constitution of the alloys of aluminium and zinc" by Messrs Rosenhain & Archbutt recently published in the Philosophical Transactions of the Royal Society, and for which you prepared the plates. The Laboratory will be marking a requisition on you for the pulls of these plates, and I shall therefore be much obliged by your keeping them [on the stone] in anticipation of this further order.' |
