The depths varied from 109 to 980 fathoms. After reading the essay carefully and comparing Prof. Lindstrom 's statements with those of his predecessors in the same kind of research, I found that he differed from every-body in opinion, and often in matters of fact. I have hitherto carefully avoided disputation in scientific matters, and I felt no disposition to reply to Prof. Lindstrom, especially as I was aware how erroneous many of his statements were. I hoped that time would bring some remarks from him after M. de Pourtales and Prof. H. N. Moseley, F.R.S., had contravened some of his assertions. But lately having been engaged in a * Kongl.
