From Mary Jung   7 January 1879

Sir,

A young austrian lady begs to allow of asking you a great favour. Endeavouring to get acquainted with the general principles and systims of the different sciences, I got the idea of possessing a little souvenir of the most celebrated men I know and so I shortly begun to make a collection of Autographes. I dont know a man, whoes opinion produced such a great revolution in this branche of science, a theory, which found such a general embracing, inspite the greatest efforts of refutation from other parts. I am partly submitted to your opinion and I remain doubting between your theory and the ecclasiastical dogma. When my reason agrees with your opinion, my heart stands to the latter and so I am in a continnual conflict with myself. I beg to excuse my speaking to you so freely, and I hope you will therefor not be unfavourable to me.

You would render very very happy by affording the request of honouring me with a single line, Yours | most thankfully and humbly | Mary Jung
