It says a soap bubble is a soap bubble a drop of water impregnated with oleate of potash or soda, and inflated with common air; but life says it is a crystal sphere, dipped in the rainbow, buoyant as hope, sensitive as the eye, with a power to make children dance for joy, and to bring youth into the look of the old....
Additional evidence of the large proportion of oleic acid was furnished by forming the lead salt, and treating with ether, in which lead oleate is soluble, the stearate and palmitate being insoluble. In this way it was found that the oleic acid obtained from the ethereal solution of the lead salt amounted to 83.15 per cent. of the oil.
But the studies of a German physicist, Professor O. Lehmann, seem to prove that even this means is not infallible. Professor Lehmann has succeeded, in fact, in obtaining with certain organic compounds oleate of potassium, for instance under certain conditions some peculiar states to which he has given the name of semi-fluid and liquid crystals.
Later the steam forming the oleate of lime and the oleate of lead, on its way to the outer air, presses it in the holes and closes them perfectly. After a year in use the tubes can be unscrewed with ease, and the screw threads are perfectly smooth. With this kind of packing only one exception must be made that is, it is only tight under pressure; condensation or vacuum must be thoroughly avoided.
From the portion of the calcium salts insoluble in alcohol, a fatty acid was obtained with a melting point and composition almost identical with the melting point and composition of palmitic acid. The aqueous portion of the separation effected by water and ether was examined for the fatty acid. The lead salts of the fatty acids were digested with ether, which dissolved out the lead oleate.
This was found to equal 546.3. This would correspond to a mixture of 18.7 parts of stearate, palmitate, and oleate of glycerine, with 81.3 parts of the same acids combined with cholesteryl. But this is largely conjecture. The boiling point of the oil is high, much above the range of a mercurial thermometer, so that it is difficult to gain an insight into its composition.
Treatment of the Local Manifestations. The skin lesions are treated on the same lines as similar eruptions of other origin. As local applications, preparations of mercury are usually selected, notably the ointments of the red oxide of mercury, ammoniated mercury, or oleate of mercury (5
