Sorry, no etymologies found.
As the boys began eagerly ruining our towels in their attempt to de-oleate the dog, I casually picked up what he'd dropped at my wife's feet, hoping to recover a really swell skipping stone.
Let me add that I have also been able to obtain such stepped laminae with alkali oleate in glycerol, and also with alkali colophonates and resinates in water.
The surface of a soapy water is greasy (low surface tension, arrest of the movements of camphor); it is, therefore, covered at least by a similar layer of oleic acid or oleate, as can be shown by analysing a known quantity of soapy water drawn in the form of laminae having a known total surface area (Jean Perrin, Mouquin).
The black spot corresponding to the maximum possible thinning would, therefore, be a kind of sandwich containing a layer of water molecules against each side of which, and glued to it by their acid groups, parallel molecules of oleic acid or oleate are arranged, the whole forming an anisotropic lamina or liquid crystalline sheet.
Without indicating here the intermediate stages which I passed through, let us say straightaway that, by observing in the microscope in bright light a small horizontal lamina of a given soapy water (approximately 5 per cent pure alkali oleate), I have seen the discontinuities multiplying of which the black spots were the first example.
December 2d I substituted for the ointment a twenty per cent solution of the oleate of mercury, of which he used a drachm morning and evening.
From this date he used the oleate only once daily, and discontinued it entirely on the
The fusion of two crystals of ammonium oleate forming a single crystal of larger size has also been observed.
I was unable to try sodium stearate directly because of the slight solubility of this substance in cold water or dilute alcohol; but I found that a mixture of sodium oleate and stearate behaved in exactly the same manner as the Castile soap.
I am not prepared at present to state the exact reaction which takes place between salts of calcium and magnesium and a compound soap containing sodium oleate and stearate.
