34, Hans Place S.W.

Dear Mr. Poincaré,

I ought long ago to have thanked you for your kind letter of the 28th May. The promised second volume of your “Méthodes Nouvelles” came to Glasgow during my absence and has been forwarded to me here.22Poincaré 1893.

I am very much pleased to have it and I find in it exactly what I wanted in regard to the equation

d2udx2=Π(x)u.

I have to thank you also for your beautiful volume “Les Oscillations Electriques” which I have also received here and which I find full of most interesting matter.33Poincaré 1894.

Believe me, Yours very truly,

Kelvin
