Page 181 - The mechanical arrangement for effecting this object was simply a steel bar, permanently magnetized, of about ten inches in length, supported on a pivot, and placed with its north end between the two arms of a horse-shoe magnet. When the latter was excited by the current, the end of the bar thus placed was attracted by one arm of the horse-shoe and repelled by the other, and was thus caused to move in a horizontal plane and its further end to strike a bell suitably adjusted.

There remained no room for doubt that the nebulae, which our telescopes...

Passing to questions bearing upon molecular activity, we are still confronted with the marvel that a few tenths per cent of carbon is the main factor in determining the properties of" steel. We are, therefore, still repeating the question, "How does the carbon act?
