Prof. P.C. Mahalanobis states:

“On Sunday mornings, Ramanujan and I often went out for long walks. One Sunday it had been arranged that we would both have our breakfast in my room and then go out for a walk. It was a cold morning with some snowfall. I was a bit late in getting up and was shaving in my bedroom when he arrived. I asked him to wait in the sitting room. When I came out, I found that he was reading Loney’s Dynamics of a particle with great interest. Seeing me, he put back the book on the table and said that it was very interesting. Evidently, he had never studied dynamics but had got interested in what he was reading.”
