My Dear Sir
Mrs Somerville <2> who has just left us and who is collecting together divers mathematical papers on the integral calculus, that branch which relates to the Logarithimitic Transcendents & the Euclidian Integrals – is very desirous to obtain copies of your two memoirs on the Integral Calculus in Phil. Trans. <3> (your pieces couronnées <4> (in 1837 & 8?)) and I have ventured to assure her that I would answer for your forwarding them to her at her address
14 Bel
14 Lower Belgrave St
Chester Square
London
if you still have any separate copies disposable; which (as she cannot take with her to Rome the Volumes of the Phil Trans) – will save her copying out the whole of the papers. – She is engaged in some enquiries connected with that Branch of Analysis.
I would also speak a good word for myself & as I bind up mathematical papers in a collection I would gladly be in possession of those myself and if you care to indulge me at anytime when you can send them to
P. Stewart Esqr <5>
65 Cornhill
London
they will reach me in safety.
I remain dear Sir yours very tly
