"He supposed it was not merely the instrument of thought, but the instrument of investigation." Hence it was futile for purposes of discovery, although important to aid processes of thought. Induction and syllogism are the two great features of his system of logic.

In our rehearsal of the stages through which the process of induction ordinarily travels, we have purposely omitted one possible interlude or parenthesis in the series; not as wishing to conceal it, but for the very opposite reason.

When a chemist announces the existence and properties of a newly-discovered substance, if we confide in his accuracy, we feel assured that the conclusions he has arrived at will hold universally, although the induction be founded but on a single instance.

There are two ways to set up the sparks and these are: with an induction coil, or spark-coil, as it is commonly called, and with an alternating current transformer, or power transformer, as it is sometimes called.

Abandoning the Morse instruments and the high voltage, recourse was then had to Professor Thomson's instruments, which proved entirely effective with ordinary battery current. Because of the effect of induction the current is much delayed in traveling through a long submarine cable and arrives in waves. Professor Thomson devised his mirror galvanometer to meet this difficulty.

Induction requires a problem, search for facts with which to solve it, comparison and analysis of those facts, abstraction of the essential likenesses, and conclusion. Deduction requires a problem, the analysis of the situation and abstraction of its essential elements, search for generals under which to classify it, comparison of it with each general found, and conclusion.

For general Geology, Professor Ansted's Introduction is excellent; while, as a specimen of the way in which a single district may be thoroughly worked out, and the universal method of induction learnt from a narrow field of objects, what book can, or perhaps ever will, compare with Mr. Hugh Miller's "Old Red Sandstone"? For this last reason, I especially recommend to the young the Rev.

There are 746 watts to 1 horsepower, and 1,000 watts are equal to 1 kilowatt. Electromagnetic Induction. To show that a current of electricity sets up a magnetic field around it you have only to hold a compass over a wire whose ends are connected with a battery when the needle will swing at right angles to the length of the wire.

Furthermore, it is supported in an overwhelming manner by the history of human thought. Every student of philosophy will tell you that the world's thought was prevailingly deductive till the days of Francis Bacon. Bacon was the first philosopher to insist that induction, rather than deduction, was the most effective method of searching for the truth.

I call the first step in the process an inductive operation, because there must be a direct induction as the basis of the whole; though in many particular investigations the place of the induction may be supplied by a prior deduction; but the premises of this prior deduction must have been derived from induction.
