Boil for two minutes; allow the precipitated calcium oxalate to settle for a half-hour, and decant through a filter. Test the filtrate for complete precipitation by adding a few cubic centimeters of the precipitant, allowing it to stand for fifteen minutes. Redissolve the calcium oxalate in the beaker with warm hydrochloric acid, pouring the acid through the filter.
Fah., and the coagulum is insoluble in acids and weak alkalies; the solution is precipitated by all diluted acids, by phosphoric acid at all the degrees of hydration, and even by a current of carbonic acid. All these precipitates redissolve with an excess of acid, sulphuric acid excepted.
For, according to the theory of mechanical evolution, the laws of redistribution of matter and motion, tho they are certainly to thank for all the good hours which our organisms have ever yielded us and for all the ideals which our minds now frame, are yet fatally certain to undo their work again, and to redissolve everything that they have once evolved.
But after I had been standing in it for a while, ten minutes maybe, a clear space had formed around my body, and I could see the ground. The heat of my body helped the air to redissolve the mist into steam. And as I watched, I noticed that a current was set up. The mist was continually flowing in towards my feet and legs where the body-heat was least.
