We have said that every substance has its own distinctive spectrum, and it might be thought that, when a list of the spectra of different substances has been prepared, spectrum analysis would become perfectly straightforward. In practice, however, things are not quite so simple. The spectrum emitted by a substance is influenced by a variety of conditions. The pressure, the temperature, the state of motion of the object we are observing, all make a difference, and one of the most laborious tasks of the modern spectroscopist is to disentangle these effects from one another. Simple as it is in its broad outlines, spectroscopy is, in reality, one of the most intricate branches of modern science.
Once in a generation, a Wallace may be found physically, mentally, and morally qualified to wander unscathed through the tropical wilds of America and of Asia, to form magnificent collections as he wanders, and withal to think out sagaciously the conclusions suggested by his collections; but, to the ordinary explorer or collector, the dense forests of equatorial Asia and Africa, which constitute the favorite habitation of the Orang, the Chimpanzee, and the Gorilla, present difficulties of no ordinary magnitude; and the man who risks his life by even a short visit to the malarious shores of those regions may well be excused if he shrinks from facing the dangers of the interior; if he contents himself with stimulating the industry of the better-seasoned natives, and collecting and collating the more or less mythical reports and traditions with which they are too ready to supply him.
Marius continued his executions and massacres until the whole of Sylla's party had been slain or put to flight. He made every effort to discover Sylla's wife and child, with a view to destroying them also, but they could not be found. Some friends of Sylla, taking compassion on their innocence and helplessness, concealed them, and thus saved Marius from the commission of one intended crime. Marius was disappointed, too, in some other cases, where men whom he had intended to kill destroyed themselves to baffle his vengeance. One shut himself up in a room with burning charcoal, and was suffocated with the fumes. Another bled himself to death upon a public altar, calling down the judgments of the god to whom he offered this dreadful sacrifice, upon the head of the tyrant whose atrocious cruelty he was thus attempting to evade.
