Well, I have got my test. I shall be as good as my word. The investigation would, I am sure, be of immense interest. Some of my colleagues might look askance at it, for science is full of unreasoning prejudices, but if Wilson has the courage of his convictions, I can afford to have it also. I shall go to him to-morrow morning--to him and to Miss Penclosa. If she can show us so much, it is probable that she can show us more.
