The most delicate flower, the tenderest insect, continues in its species through countless years; always varying, yet ever the same. When we think we have discovered a departure, as in the 'Aphides, Medusæ, Distomæ, &c. , the law concerned is itself the best means of instituting an investigation, and hitherto we have always found the witness to return to its original testimony.

I do not object to table-moving, for itself; for being once stated, it becomes a fit, though a very unpromising subject for experiment; but I am opposed to the unwillingness of its advocates to investigate; their boldness to assert; the credulity of the
