Dear Sir,
The Strasburg Cathedral is certainly a very [illegible] plate, with magnifier as well as naked eye.
The 2 positives you have of Mt Guajara, are intended if you please for your kind acceptance, not for loan only. The positive which you put on the copper plate, is the one required as a complement to that which the Stationery Office is working from: and it is distinguishable by the Mountain being on rather a smaller scale than on the other, viz. the Stationery Office edition, & your steel plate picture.
I duly note your instructions for the small positive still to be made, & remain
Yours very truly
C. Piazzi Smyth
