A letter from Mr. Blackburn, on the subject of the spelling of a hill in Inverness-shire, called on the 6 inch Ordnance Map "Am Fros-bheinn" has been forwarded to me, as the examination of the part of Scotland in which the hill is situated, was done by this Division.
I wrote to Mr Robertson Macdonald who owns a portion of this hill to ascertain from him what he considered to be the correct mode of spelling this name,his letter is forwarded herewith: from his letter it appears to be quite clear that Mr Blackburn is quite wrong, in Gaelic there is apparently no v, bh stands for it.
Mr Robertson Macdonald takes exception to the 'Am', but this is merely the definite article, it might however be omitted as it appears to be the

[Notes written to the left of the letter]
"Fros-bheinn" to be adopted as the spelling, the "Am" to be omitted.
The 6 inch plate to be altered accordingly

Is Mr. Blackburn to be answered accordingly?
GnS

Yes, - that it appears that the present spellings are corruption of "Am Fros-bheinn", But that the "Am" will be omitted as not essential which will assimilate the name phonetically to that which is now used
