Non-parasitic skin diseases are caused by irritation to the skin and internal causes. Irritation to the skin may be either chemical, thermic or mechanical. The internal causes may be due to an individual predisposition together with digestive disturbances and the eating of feeds too rich in protein. In this chapter parasitic skin diseases produced by insects will not be discussed.

If they are right, we must conclude that the ancient and widespread faith in the medicinal virtue of mistletoe is a pure superstition based on nothing better than the fanciful inferences which ignorance has drawn from the parasitic nature of the plant, its position high up on the branch of a tree seeming to protect it from the dangers to which plants and animals are subject on the surface of the ground.

As he stood there he resembled more than anything a beautiful tiger-cat, a wonderful thing of strength and will-power, indomitable and insatiate. Yet who could tell whether this strength was not, after all, parasitic. If Ethel's suspicions were justified, then, indeed, more had been taken from him than he could ever realise.

The last of this long series of researches is that of Hamann , who investigates the similar structures which occur in the oral region of the Rhizostome jelly-fishes. While agreeing with Cienkowski as to the parasitic nature of the yellow cells of Radiolarians, he holds strongly that those of anemones and jelly-fishes are unicellular glands.

He may be brilliant: his brilliancy of intellect, by causing him to be courted, may lead him into idleness, and idleness is the bed whereon parasitic vices flourish rankly. Take warning. I was invited to go for a drive, but I had letters to write, and said so.

The very churches whose domes rise to the northward of the ancient remains are built of looted stones and look like parasitic and fungoid growths, and the tourists stream through those spaces day by day, stare at the marble fragments, the arches, the fallen carvings and rich capitals, with nothing greater in their minds and nothing clearer....

For a while the men absorbed and reflected the intellectual life, for there still ran in their veins the good red blood of their sturdy grandmothers. But the race was doomed by the indolent, self-indulgent and parasitic females. The women did not all degenerate. Here and there were found women on whom wealth had no power.

It was, in a word, one of those polite, parasitic occupations for women, provided by the rich for helpless friends, and it was satisfying to neither party. A good deal of time for both was wasted in "talking things over," with much discursive chatter on matters in general, and all sorts of consulting back and forth about the job to be done.

They are too helpless: their lives are too frail. A weasel or a mouse that gets its own living is more interesting. I like to think that the animals about us have souls something like our own, and either carry on their own little affairs or can be companions to us, like Monk here. Those creatures are parasitic." "I am so glad I know that you do not like them," said good Sir James.

The unfortunate introduction of the English sparrow into this country is mentioned, and the equally unfortunate introduction of the East Indian mongoose into the West Indies as well. The fear is expressed that the beneficial parasitic insects, after they have destroyed the injurious insects, will either themselves attack valuable crops or do something else of an equally harmful nature.
