In the letter quoted in the above-named page, the Envoy alludes to the system of secret writing which has now superseded the old plan of correspondence by cypher; and as at a later period, during General Pollock’s occupation of the passes between Peshawur and Caubul, it was found of the utmost service to our officers, it may be interesting to describe the method in the words of the Envoy: “Are you in possession of the _hikmut_ of concealed writing, by means of conjee-water and a solution of iodine? This is much better than any cypher. The paper is to all appearance blank, but when rubbed over with the solution, the words written with conjee-water start into life, as it were, most miraculously. Something unimportant is generally written with common ink, and what is intended as secret is interlined with conjee-water. Try this some day. Any medical man in your neighbourhood will give the solution. The paper intended to be used should first have a gentle coat of the solution passed over it, and suffered to dry.” In another letter to the same correspondent, the Envoy again adverts to this mode of cypher writing: “I find it is not necessary to prepare the paper in the first instance. You write on ordinary paper, and having spread a solution of iodine over it, the invisible writing becomes apparent. When there is any writing of this kind on my paper, I shall put the day of the month in letters, instead of figures. Perhaps you would adopt the same sign.” SIR WILLIAM MACNAGHTEN AND THE PRICE OF BLOOD. [_Book V., chapter 5, pages 265-267._] [The following passages, containing much authentic evidence relating to this painful subject, is extracted from the _Friend of India_ (Serampore newspaper).] “To crown the evidence of Sir William Macnaghten’s never having been implicated in this alleged assassination of the two chiefs, we have an acknowledgment under Mohun Lal’s own signature. When he was claiming remuneration for his services of the Court of Directors, he delivered in the following document, which has been copied for us from a paper in his own hand-writing. Advanced to Abdool Aziz, who offered to kill Abdoollah Khan, by such means which the Envoy did not approve, therefore the Rs. balance 11,000 rupees was not paid. 4,000 “Thus it appears that while Mohun Lal told the Reviewer that Sir William objected to pay the balance, because he had not seen the heads; he told the Court of Directors that the balance was not paid because the Envoy did not approve of the means that had been used!” * * * * Major Colin Troup writes thus in a letter now before us:
