Wellclose Sq | 17 Feb 1840

My dear Sir,

I am very much obliged to you for the account of the mixing of the Gases, which is all that I require, and I am further indebted to you for directing my attention to the variations in the bulk of the aqueous vapour, from variations of temperature. I meant to have thanked you personally on Friday last², but Business prevented me[.]

I enclose a rect. for the R. Soc. & am My dear Sir | Yours much obliged | N.B. Ward
