‘I will lend it you if you like: it is one of those books one must read. It explains everything, and is written in a very agreeable style.’

‘It explains everything!’ said Tancred; ‘it must, indeed, be a very remarkable book!’

‘I think it will just suit you,’ said Lady Constance. ‘Do you know, I thought so several times while I was reading it.’

‘To judge from the title, the subject is rather obscure,’ said Tancred.

‘No longer so,’ said Lady Constance. ‘It is treated scientifically; everything is explained by geology and astronomy, and in that way. It shows you exactly how a star is formed; nothing can be so pretty! A cluster of vapour, the cream of the Milky Way, a sort of celestial cheese, churned into light, you must read it, ‘tis charming.’

‘Nobody ever saw a star formed,’ said Tancred.

‘Perhaps not. You must read the “Revelations;” it is all explained. But what is most interesting, is the way in which man has been developed. You know, all is development. The principle is perpetually going on. First, there was nothing, then there was something; then, I forget the next, I think there were shells, then fishes; then we came, let me see, did we come next? Never mind that; we came at last. And the next change there will be something very superior to us, something with wings. Ah! that’s it: we were fishes, and I believe we shall be crows. But you must read it.’

‘I do not believe I ever was a fish,’ said Tancred. ‘Oh! but it is all proved; you must not argue on my rapid sketch; read the book. It is impossible to contradict anything in it. You understand, it is all science; it is not like those books in which one says one thing and another the contrary, and both may be wrong. Everything is proved: by geology, you know. You see exactly how everything is made; how many worlds there have been; how long they lasted; what went before, what comes next. We are a link in the chain, as inferior animals were that preceded us: we in turn shall be inferior; all that will remain of us will be some relics in a new red sandstone. This is development. We had fins; we may have wings.’

Tancred grew silent and thoughtful; Lady Bran-cepeth moved, and he rose at the same time. Lady Charmouth looked as if it were by no means necessary for him to depart, but he bowed very low, and then bade farewell to Lady Constance, who said, ‘We shall meet to-night.’

‘I was a fish, and I shall be a crow,’ said Tancred to himself, when the hall door closed on him. ‘What a spiritual mistress! And yesterday, for a moment, I almost dreamed of kneeling with her at the Holy Sepulchre! I must get out of this city as quickly as possible; I cannot cope with its corruption. The acquaintance, however, has been of use to me, for I think I have got a yacht by it. I believe it was providential, and a trial. I will go home and write instantly to Fitz-Heron, and accept his offer. One hundred and eighty tons: it will do; it must.’
