John William Lubbock to Faraday   26 June 1836

M. Faraday Esq

29 Eaton Place | 26 June 1836

My dear Sir,

Mr Russell¹ has examined Mr Sturdy's experiment upon three mixtures²[.]

Sp 972, 985 and 984 at 62°

It is curious that the weaker spirit comes out better than the stronger.

The greatest error is about 3/10ths of a gallon of spirit in a mixture containing 100 gallons of spirit & water & this error corresponds to an error of about .0003 in Sp. Gr. only.

Mr Russell tells me the Table will take a fortnight longer they will fill 200 pages.

Pray return the enclosed to 29 Eaton Place.

Yours very truly | J.W. Lubbock

Enclosed 4 papers

The differences of Table 1 for variations in the temperatures given to indicate that the specific gravities at 80° are too great.
