02 本文
略記はそのまま残した(yr = your、ye = the、wch = which)。
Sr. — I have yr Honr of sending you inclosed a List of Names of most of the Ministers actually employed by the several Courts of Europe, in publick Affairs, which I intended to insert into the new French Cypher, and beg you will send it me back with the Additions or omissions that may be thought proper; I have added a List of names, that though in the English Cypher are either dead or no more in a publick Capacity, & in regard to wch I beg to be instructed. I did not think it necessary to send you also a List of the Places, Countries &c. I kept all those that are found in the English Cypher, & added many more, particularly ye names of most of the European Settlements in Asia, Africa, & America, as those places will chiefly be ye Subject of French Papers that may be wanted to be put into Cypher. As for ye rest, I shall make it in ye same manner as ye English, with ye same number of Cyphers, viz. 3000. and bring likewise in several Blanks.
In Order to disguise it sometimes, without ye help of a Second Cypher, I propose several Methods, for Instance, by taking ye Figures of every Cypher backwards, E.G. 1753. write 3571. and vice versâ in decyphering it; Item, by putting ye first figure at ye End, E.G. 1753. write 7531. Item by putting ye last figure at ye head, as 1753 write 3175. & both vice versâ in decyphering. Item by adding any indifferent figure at ye head or end of each Cypher, wch is then only to be taken off in decyphering, E.G. 1753. write 21753, or 17536. Each of these Methods might be marked where it begins, by two or three Cyphers like the Change the Cypher in the last English Cyphers; & some other marks, where it changes again into the natural way. To avoid Confusion, I wd add a Note that these different Methods are not to be minded, or to follow one another immediately, without Changing before into ye natural way.
I beg ye favour you will let me know, wch of these several Methods I may make use of, & as soon as I am honoured with yr Answer, I shall only want a week’s Time to put it entirely in order, & transmit a fair Copy of it. I shall do my Utmost Endeavours to make it as compleat as possible, & flatter myself to succeed as far as can be expected. — I have ye Honour &c. C. Ben. Schaeblin. To Mr Jones.
03 不確かな点
- “not to be minded” はおそらく “mixed” または “mingled” の意である(C)。いずれにせよ意味は明らかである。
- Schaeblin と Jones が何者であったかは、ここでは確定していない。手紙からわかるのは、Schaeblin がハーグで英国側のために暗号を作成していたということである。
- 3000群からなるそのフランス語暗号は、DECODE 上の同じシリーズの94件の鍵の記録の中に残っているかもしれない(最も近いのは R9219、1760年)。未確認。
