Hence it follows that the gelatine plate is acted upon by light only on the parts corresponding to the ridges; and in these parts the gelatine is rendered insoluble, while all the rest of the gelatine is soluble. Thus there is produced a facsimile in relief of the finger-print having actual ridges and furrows identical in character with the ridges and furrows of the finger-tip.
Whoever wishes to prepare dry gelatine only requires, when the washing is over and the vessel perfectly emptied, to leave the emulsion to drip for a time, and then to lift out the sieve and its contents and place it in a suitable vessel with absolute alcohol.
"Happily," he said, "I am an eupeptic, energetic sort of person on principle. I would all men were likewise." "It's the best way," agreed Mr. Hoopdriver, and the conversation gave precedence to bread and butter. "Gelatine," said the clergyman, presently, stirring his tea thoughtfully, "precipitates the tannin in one's tea and renders it easy of digestion."
A single bacterium in the midst of such a stiffened mass will feed upon it and produce descendants rapidly; but these descendants, not being able to move through the gelatine, will remain clustered together in a mass, which the bacteriologist calls a colony.
BONE contains cartilage, gelatine, fat, and the salts of lime, magnesia, soda, &c., in combination with phosphoric and other acids. CARTILAGE consists of chondrine, a substance somewhat like gelatine, and contains also the salts of sulphur, lime, soda, potash, phosphorus, magnesia, and iron.
Certainly not for their horny matter; nor for chondrin, the proximate chemical element of cartilage; nor for gelatine; nor for syntonin, the constituent of muscle; nor for their nervous or biliary substances; nor for their amyloid matters; nor, necessarily, for their fats. It can be experimentally demonstrated that animals can make these for themselves.
Two large but quite worthless oil paintings hung above the fireplace and the sideboard respectively, and the window was covered with gelatine paper simulating stained glass. Inspector Willis stood surveying the scene with a frown on his brow. How on earth was he to secrete himself in this barely furnished apartment? There was not room under the sofa, still less beneath the sideboard.
Partly from a vague desire to keep in with the Fineberg clan, but principally because it struck him as rather a doggish thing to do, Roland had passed over the ten shillings; and there, as far as he had known, the matter had ended. And now, after all this time, that simple action had borne fruit in the shape of Gelatine and a check for five hundred pounds. Roland's next emotion was triumph.
Another interesting light phenomenon is found in the observed fact that very many substances become markedly phosphorescent at low temperatures. Thus, according to Professor Dewar, "gelatine, celluloid, paraffine, ivory, horn, and india-rubber become distinctly luminous, with a bluish or greenish phosphorescence, after cooling to 180° and being stimulated by the electric light."
Grate the yellow rind of two Florida oranges and two lemons, and squeeze the juice into a porcelain-lined preserving kettle, adding the juice of two more oranges, and removing all the seeds; put in the grated rind a quarter of a pound of sugar, or more if the fruit is sour, and a gill of water, and boil these ingredients together until a rich syrup is formed; meantime, dissolve two ounces of gelatine in a quart of warm water, stirring it over the fire until it is entirely dissolved, then add the syrup, strain the jelly, and cool it in molds wet in cold water.
