"This wretched want of water," he said, "is the sole obstacle to the success of my project. In the entire gallery, made of lava, schist, and coal, it is true we found not one liquid molecule. It is quite possible that we may be more fortunate in the western tunnel." My sole reply was to shake my head with an air of deep incredulity.

There are millions of them. A single very large molecule may give off 1,000,000 different wave lengths at the same time. The longer wave lengths of this sort travel with the ease and speed of radio waves. . . . There is one amazing difference between the new radio rays and familiar rays like light.

The inner organisation of the oxygen molecule is a considerably plastic one. It is readily modified by heat, and these modifications are reflected in its varying modes of radiating light. Dr. These persist down to the lowest temperatures, and even survive a change of state. They are produced essentially the same by liquid, as by aërial oxygen.

We may assume that a molecule is surrounded by continuous ether, more of the nature of a jelly than of that of a gas; in such a medium a molecule might freely vibrate through small arcs, but a rotation extending beyond its critical limit would involve a much greater expenditure of force.

We cannot well miss Cleopatra's Needle, if we are in its neighbourhood; but no one has seen a single molecule or a single electron, yet the characters of events are only explicable to us by expressing them in terms of these scientific objects. Undoubtedly molecules and electrons are abstractions. But then so is Cleopatra's Needle.

This is, in reality, a very simple problem in proportion, making use of the atomic or molecular weights of the substances in question which are chemically equivalent to each other. The molecular weight of BaSO is 233.5. There is one atom of S in the molecule and the atomic weight of S is 32.1.

In the Far East the social unit, the ultimate molecule of existence, is not the individual, but the family. We occidentals think we value family. We even parade our pretensions so prominently as sometimes to tread on other people's prejudices of a like nature. Yet we scarcely seem to appreciate the inheritance.

It must therefore be admitted that an atom of radium, in disaggregating itself, liberates 30,000 times more energy than a molecule of hydrogen when the latter combines with an atom of oxygen to form a molecule of water. We may ask ourselves how the atomic edifice of the active body can be constructed, to contain so great a provision of energy.

His restless energy permeated every molecule in the economic structure over which he presided, roused it to intense vibration. Not for an instant was there a resting spell. The veriest chore-boy talked, thought, dreamed of nothing but saw logs. Men whispered vaguely of a record cut.

Each molecule of food, ingested for assimilation into our substance, accumulates a history of wanderings and pilgrimages, attachments and transformations beside which the gross trampings of a Marco Polo become the rambling steps of a seven-league booted giant.
