After his day's work at his uncles' business, he took evening classes at University College London (the only university in London which did not require students to be Anglican). There, he obtained a degree in botany (the only subject which offered evening classes). He learned German and Italian. He also took part in fencing, horse-riding and rowing, although circumstances did not allow him to keep these up. He had also become very scholarly, and started to publish — an anthology of poems in 1862 and numerous articles in London periodicals, on the British press and the growing of cotton in Greece.
