It is well known that never more than a very small store of honey is found in felled trees inhabited by stingless Melipona. What should induce the Melipona to accumulate stores which they could not preserve? They lack formic acid. Only three of the eighteen different known species of honey bees of northern Brazil have a sting.
"Yes, THAT'S comparatively decent," said the doctor reflectively. "It's only sawdust mixed with a little gum and formic acid." "Formic acid? Wot's that?" "A very peculiar acid secreted by ants. It is supposed to be used by them offensively in warfare just as the skunk, eh?" But Poker Jack of Shasta had hurriedly declared that he wanted to speak to a man who was passing, and had disappeared.
"Why that is the very first lesson Daddy ever taught me when he took me to the mountains and the desert. If you are afraid, your system throws off formic acid, and the animals need only the suspicion of a scent of it to make them ready to fight. Any animal you encounter or even a bee, recognizes it.
She puts the nectar through a process of her own, adds a drop of her own secretion to it, namely, formic acid, the water evaporates, and lo! the tang and pungency of honey! There can be little doubt that in his practical daily life we may credit Thoreau with the friendliness and neighborliness that his friend Dr. Edward W. Emerson claims for him. In a recent letter to me, Dr.
Undoubtedly when I am in the crowd, poisoned by contact with the crowd- mind the formic acid of the spirits I am not actually or keenly conscious of the great gulf between me and the others, but, as in the former case, the sense of relief is experienced here too in escaping from it. The people of the small rustic community have not been de- humanised.
They are a part of the equipment which enables us to adjust our selves to our environment. The secretions and excretions are perspiration and sebum. These contain water, carbonic acid, urea, buturic acid, formic acid, acetic acid, salts, the chief being sodium chloride, and many other substances.
It manifests this peculiarity because of the volatile formic acid which it contains. This admixed acid confers upon crude honey its preservative power. Honey which is purified by treatment with water under heat, or the so-called honey-sirup, spoils sooner, because the formic acid is volatilized. The honey of vicious swarms of bees is characterized by a tart taste and a pungent odor.
Most of England had an Alpine climate probably once, and some Alpine plants and animals have been stranded on the tops of our highest hills and remain there to this day. In those icy times English lungs were probably free of disease. Has formic acid ever been used for experiments on bacilli? It is the ant acid; they are full of it, and it is extracted and used for some purposes abroad.
Then he tried, each in turn, some oxalic, cyanic, acetic, phosphoric, chloric, hyperchloric, sulphuric, boracic, silicic, nitric, formic, nitrous nitric, and carbonic acids. Mrs. Peterkin tasted each, and said the flavor was pleasant, but not precisely that of coffee.
Here we have a contrary effect it is the insects which have been transformed; the millions of wood-ants, let us say, inhabiting an old and exceedingly populous nest have been transformed into men, but in form only; mentally they are still ants, all silently, everlastingly hurrying by, absorbed in their ant-business. You can almost smell the formic acid.
