Dear Sir,

A New Catadioptric Light apparatus of the 1st Order having been provided by Messrs. Wilkins & Co. for the Bishop Rock Light (Scilly) I beg to apprise you that the same is now ready for Inspection at their premises in Long Acre, and I am to request that you will favor the Elder Brethren by making an examination thereof & furnishing me with a Report of the result, for their information.- They will be obliged by as early an Inspection being made as may accord with your convenience.-

I am | Dear Sir, | Your’s faithfully | P.H. Berthon
