to invention, to the classification of facts, and the building up of hypotheses, before reaching the goal of his desires. Men will marvel at the shortness of the period when all that he has accomplished is made known. The delays which have occurred in bringing before the world the actual discovery of this primal force, from which all the forces of nature spring, have been in part occasioned by the want of that sympathy and appreciation which Keely would have received from his fellow-men, had scientists believed him to be honest in his claims. He would not then have been left in the merciless hands of "a ring," which gave or withheld financial aid according as he could be "thumbscrewed," into giving exhibitions for speculative ends on the part of "the ring." These costly days of delay are now a thing of the past. Keely's programme of work for the remainder of the year embraces such exhibitions of his progress as can be given without interfering with this programme. Coleridge says in "Table Talk,"--"I have seen what I am certain I would not have believed on your telling; and in all reason, therefore, I can neither expect nor wish that you should believe on mine." It is of all tasks the most difficult to procure any favourable reception for doctrines which are objectionable only because they are deemed to be incompatible with preconceived notions. It does not answer to disturb the calmness of views now held by our most eminent physicists, who seem to expect that nature will always accommodate her operations to their preconceived notions of possibility, and adapt her phenomena to their arbitrary systems of philosophy. We are all familiar with the anecdote of the wise Indian potentate who imagined that his informant was imposing upon his credulity when giving him an accurate description of the steam-engine. Now what would be thought of that philosopher who, in attempting to communicate an adequate idea of the operation of the steam-engine, should content himself with a mere description of its mechanism--of its wheels and levers, and cylinders and pistons--keeping entirely out of view the moving power--the steam; and ridiculing all investigation into the nature, application, and phenomena of this power. Yet this is exactly what microscopic observers of the animal economy call "absurd and useless inquiry." The true springs of our organization are not these muscles, these arteries, these nerves, which are described and experimented upon with so much care and exactness. They are hidden springs, the action of which are as miracles to those who have vainly tried to account for the motion of the muscles at the command of the will; for the power of vision, which places the human eye in intimate and immediate connection with the soul--dependent as they are upon unknown laws, assigned them by the great, omniscient and omnipotent Being by whom they were originally created, and Who is the one source of all power.
