Messrs Ballantine & Allan.

Gentlemen

By the arrival of the Steamer Cambria last evening, in the short passage of 11 days, I am enabled to answer by tomorrow's steamer, your favours of the 2^d & 15^th inst.... In reply to your inquiries. The sheets of glass are to be exactly of the size of the paper patterns. But if there is a metal rim put round the glass by you, it is to be considered as part of the glass, so that the whole diameter shall not exceed that of the paper pattern. We shall add to the cast iron of the long windows, a small wooden rebat, up which the glass, or lead, will be cemented. It will project over the glass about a quarter ^1/4 of an inch or 3/8.

By referring to my letter of June 14^th you will find that in the Nave window, the whole daylight space between the mullions is 12 feet 10 inches in height, measuring from the bottom of the bases, to the tops of the caps of the mullions. (see an accompanying plan.) From this height you may deduct about 1 1/2 inch for the width of a crossbar at bottom, & you will then have the height to where

the paper patterns begin. The width of glass between the mullions is one foot 9 1/2 inches, as stated in the former letter.

In the same letter you will find that the height of the mullions in the aisle windows is 8 feet from the tops of the bases to the bottom of the caps.

The caps & bases measure together 9 inches, making the total daylight up to the paper patterns 8 feet 9 inches.

From this deduct two crossbars, for these windows shove up,) or about 3 inches, leaving the total height of straight glass 8 feet 6 inches. Width 18 1/2 inches.

I return herewith the colored designs which you sent, also a plan with figures, to care of Harnden & Co. Liverpool, who will forward them to you --
