Crossing the Red Sea into Arabia, Persia, Mesopotamia and Asia Minor, you will find the same or rather a more complete lack of color. This is merely the cartographer's way of showing, by tint and lack of tint, that at that time Africa and Western ...

... must needs have been, regarded as very distinct species, each mainly with its own geographical area, are found to mingle their characters along bordering lines; and the same kinds of differences (of coloration, form, or other) are found to prevail through the species of each region, thus impressing upon them a geographical facies. Upon a submergence of the continent, reducing these several regions to islands sufficiently separated, these forms ...

... initiated only. The much discussed early and middle and later manners of James are only various campaigns of this one questing spirit, changing his procedure as the elusive object of his search hid itself by this or that device of protective coloration or swift escape. It is as if a collector of rare butterflies had one method of capturing them in Madagascar, another for the Orinoco, and still another for Japan—though Henry James found his Japan—and Orinoco and Madagascar all ...

... hydroxide solutions precipitate green chromium hydroxide from solutions of chromic salts; the precipitate is soluble in excess of the cold alkali, but is completely thrown down on boiling the solution.

... carried out thus: Add to the liquid in the beaker a few drops of the ferric-alum solution to act as an indicator, and from a burette carefully drop in centinormal ammonic thiocyanate until a permanent red coloration of ferric thiocyanate barely appears. The number of cubic centimeters used of the thiocyanate solution multiplied by 0.00168 gives the amount of uric acid in the 25 c.c. One milligramme may be added to compensate for loss, and the whole multiplied by four gives the percentage of uric ...

There are many biologists who seriously question whether protective coloration, as Darwin called it, is as effective as he believed it. In some quarters it is the present fashion to doubt protective coloration entirely. No one has yet shown any principles which will better explain ...

To distinguish between them apply solution of hydrate of lime, whereby a change to gray, followed by complete decoloration indicates logwood, and ...

In 1880, the opening of a cave of the Stone age in the district of Anagni, a short distance from Rome, brought to light the facial portion of a human cranium, colored bright red with cinnabar. Nor are these by any means exceptional cases, for similar coloration was noticed on bones picked up at Finalmarina and several other places in Liguria and Sicily. The custom had therefore become general in the Neolithic period in the whole of the Italian peninsula.[283] We also meet with it in other countries; at the ...
