      "You mustn't do anything like that again," he muttered hoarsely. "Youmustletmeknowwhenyoufeel itcoming on."Allingham did so. Just on the edge of the lining there was an oblong-shaped tab, with small gold lettering:


      V.ON THE BATTLE-FIELDS


      Scepticism, as a philosophical principle, is alien from early Greek thought; but it is pervaded by a negative tendency exhibited in four different directions, all converging towards the later attitude of suspensive doubt. There are sharp criticisms on the popular mythology; there are protests against the ascription of reality to sensible appearances; there are contemptuous references on the part of some philosophers to the opinions held by others; and there are occasional lamentations over the difficulty of getting at any truth at all. The importance, however, of these last utterances has been considerably exaggerated both in ancient and modern times. For, in some instances, they are attributable solely to the distrust of sense-perception, and in others they seem to express nothing more than a passing mood against which we must set the dogmatic conclusions elsewhere enunciated with perfect confidence by the same thinkers.219 At the same time, we have to note, as an illustration of the standing connexion between theological belief and that kind of scepticism which is shown by distrust in mans power of discovering the truth for himself, that the strongest expressions of such a distrust are to be found in the two most religious of the pre-Socratic thinkers, Xenophanes and Empedocles.

      "How did you know that?" Charlton asked.Primarily, power is a product of heat; and wherever force and motion exist, they can be traced to heat as the generating element: whether the medium through which the power is [30] obtained be by the expansion of water or gases, the gravity of water, or the force of wind, heat will always be found as the prime source. So also will the phenomenon of expansion be found a constant principle of developing power, as will again be pointed out. As steam-engines constitute a large share of the machinery commonly met with, and as a class of machinery naturally engrosses attention in proportion, the study of mechanics generally begins with steam-engines, or steam machinery, as it may be called.


      "The notes! I had more important matters to think of. I found matches and lighted the gas. And there sitting opposite me was Charlton. It was part of my wretched luck that I should have stumbled on him in this disguise. Had I been differently dressed he would never have recognized me. I----. Faster, faster."

      CHAPTER XLV. A CHASE.In sketches and drawings made for practice, such as are not intended for the shop, it is suggested that metrical scales be employed; it will not interfere with feet and inches, and will prepare the mind for the introduction of this system of lineal measurement, which may in time be adopted in England and America, as it has been in many other countries.

      The time in which the contraction takes place is as the temperature of the bath and the cross section of the piece; in other words the heat passes off gradually from the surface to the centre.
