In addition to this, the circumstance that these lines occur in groups, renders the observation of the coincidence of these spectra more exact than is the case with those composed of single lines.

Seite 176 - ... rear a sound fabric of mental science on any other foundation. To begin the study of mind, then, with the observation of its humblest bodily manifestations, is a strictly scientific method. When we come to inquire what these are, it is far from easy to fix the point at which mental function begins. Without doubt most of the actions of man, and many of those of the higher animals, do evince the operation of mind, but whereabouts in the animal kingdom it first appears, and what part it has in the...
Seite 148 - That man should be able to measure with certainty such minute portions of space and time, is not a little wonderful ; for it may be observed, whatever theory of light we adopt, these periods and these spaces have a real existence, being in fact deduced by Newton from direct measurements, and involving nothing hypothetical but the names here given them.
Seite 149 - His first suspicion of this arose when he was about four years old.

That test-images may be formed of a high order of delicacy and accurate portraiture in miniature, by employing an objective of twice the focal depth, or, rather, half the focal length of the observing objective. (III.) That such test-images (which may be obtained conveniently two thousand times less than a known original) are formed (under precautions) with a remarkable freedom from aberration, which appears to be reduced in the miniature to...
Seite 191 - Fraunhofer's lines. For it is very probable that elementary bodies which occur in large quantities on the earth, and are likewise distinguished by special bright lines in their spectra, will, like iron, be visible in the solar atmosphere. This is found to be the case with calcium, magnesium, and sodium.
