London Times, 9 December 1870, p. 10: RUSSIANS AT OUR ARSENALS.
To the editor of the Times.
Sir, -- Your Portsmouth correspondent has very properly called attention to the special facilities afforded by our naval and military authorities to Russian officers, thereby enabling the latter to obtain the most precise information.
I may add that within the last few months a Russian Engineer officer, well known for his high scientific attainments, has had constant admission to Woolwich Arsenal, and that the officials were requested to furnish him with any information he might require.
Is it wise to place any foreign Government in possession of the results of experiments obtained by England with so much labour and expense?
I am, Sir, yours, &c., R.A.
