From Mary Somerville   [15 May 1830]

[In pencil: 15 May 1830]

My dear Sir,

As you kindly said you would not think it a trouble to look over my MSS after I had made the alterations I intended I send it but not without some hesitation although I dare not print without knowing that it does not contain any great blunders. Do not be alarmed at seeing the whole, as such I wish you to judge of it the greater part you have already looked at, and to save your time I have marked the passages of which I am doubtful. The introduction is altogether new.

From page 49 to 133 you did not send back.

I cannot let you forget your promise of giving me your two new works, I value those I have got so highly that I look forward with real pleasure to every thing that comes from your pen. I trust Mrs Herschel and the baby are quite well offer my kindest regards to her and believe me ever

gratefully yours

M. Somerville
