“My dear nephew was only in his sixth year when I came to be detached from the family circle. But this did not hinder John and I from remaining the most affectionate friends, and many a half or whole holiday he was allowed to spend with me, was dedicated to making experiments in chemistry, where generally all boxes, tops of tea-canisters, pepper-boxes, teacups, &c., served for the necessary vessels, and the sand-tub furnished the matter to be analysed. I only had to take care to exclude water, which would have produced havoc on my carpet.”

“As an astronomer in the true sense of the term, Sir John Herschel stood before all his contemporaries. Nay, he stood almost alone.”
― Richard a Proctor

“Among the many things that I showed Sir John [Herschel] while at Hammerfield, was a piece of white calico on which I had got printed one million spots. This was for the purpose of exhibiting one million in visible form. In astronomical subjects a million is a sort of unit, and it occurred to me to show what a million really is. Sir John was delighted and astonished at the sight. He went carefully over the outstretched piece with his rule, measured its length and breadth, and verified its correctness.”
