There may be added to the boiler, C, certain materials for purifying the acetic acid, such as permanganate of potassa or acetate of soda, so as to obtain an absolutely pure article. Dingler's Polytech. Journal. We illustrate the field kitchens of Captain J.C. Baxter, R.E., in the Inventions Exhibition.
Very naturally it tries to get at the place with its right foot to remove the acid. You then cut off the frog's head, and put more acetic acid on the some place: the headless frog, or rather the body of the late frog, does just what the frog did before its head was cut off it tries to get at the place with its right foot.
It is true one may, with proper preparations and with the help of the pocket lens or microscope, follow the development while there may be no external signs of the process evident. The acetic acid contained in the mixture, one part water to one part wine vinegar, causes the material of the embryo proper to coagulate, while the yelk remains clear.
The above is mainly taken from M. Ribot's work on heredity rather than Dr. Carpenter's, because M. Ribot tells us that the head of the frog was actually cut off, a fact which does not appear so plainly in Dr. Carpenter's allusion to the same experiments. But Dr. Here is a frog whose right thigh you burn with acetic acid.
If buttermilk cannot be had, acetic acid or vinegar, or the juice of lemons, may be mixed with sweet milk or even water, until the mixture attains about the usual sourness of buttermilk. This makes an efficient substitute. Buttermilk Poultice. Boiled potatoes beaten up with fresh buttermilk make an excellent poultice for all eruptive sores, scabbed heads, and heated skin affections.
Platinum in a very fine state of division known as platinum black, or noir de platine has the very singular property of causing alcohol to change into acetic acid with great rapidity.
One pound of granulated sugar; half a pound of chocolate; one teaspoonful of acetic acid; one tablespoonful of water; one teaspoonful of vanilla. Melt the sugar slowly, wetting a little with the water. Add the acid and vanilla, and boil till sugary, trying very often by stirring a little in a saucer.
Cider and perry drinkers were said to be more or less immune from many human ailments, including rheumatic affections, though one would expect the acetic acid they contain, unless very carefully made, would have an opposite effect.
In the head, D, they are separated into two portions, viz., into concentrated acetic acid, which condenses by reason of its high boiling point, and into steam, which distills and carries along but a very small amount of acetic acid. This steam passes through the pipe, G, into the worm, H, condenses, and afterward flows into the vessel, N.
Certain acid- producing bacteria after a little begin to grow slowly, and in time the silage is rendered somewhat sour by the production of acetic acid. But the exclusion of air, the close packing, and the small amount of moisture appear to prevent the growth of the common putrefactive bacteria, and the silage remains good for a long time.
