Dear Romanes

When I wrote yesterday, I had not received todays Nature & I thought that your Lecture was finished.— This final part is one of the grandest essays which I ever read.² It was very foolish of me to demur to your lines of conveyance, like the threads in muslin, knowing how you have considered the subject; but still I must confess I cannot feel quite easy.³ Everyone I suppose thinks on what he has himself seen & with Drosera, a bit of meat put on any one gland on the disc causes all the surrounding tentacles to bend to this point; & here there can hardly be differentiated lines of conveyance. It seems to me that the tentacles probably bend to that point whence a molecular wave strikes them, which passes through the cellular tissue with equal ease in all directions in this particular case.— But what a fine case that of the Aurelia is!⁴
