reduced to a fine saponaceous substance . —Its efficacy was fully established by experiments , and a patent was obtained . According to Ingenhouz , plants suffer oxygen to be disengaged m the light , and the carbonic acid in darkness . Ssnebier is of opinion that the litter changes the oxygen into tlie carbonic acid , by furnishing it with carbon . Humboldt has observed that mushrooms furnish hy drogenous gas in the
day as well as the night-time . STARCH . Mrs . GIBBS has discovered a mode of preparing Starch from the roots of drum macutatum , a plant found in the common fields .
COLOURS . Mr . MURDOCK , Redruth , has produced from the same materials , and by processes entirely new , copperas , vitriol , and different sorts of dying stuff , paint , and colours , and also a composition for preserving the bottoms of vessels . This invention consists in collecting a quantity of mundic and pyrites , containing sulphur , copper or iron , zinc and arsenic ; with these materials a common sulphur kiln is to be chargedand a gentle heat to be
, applied : part of the sulphur , and the zinc and arsenic , in the state of oxide , will rise together into the receiver in the form of a bright yellow sublimate , which constitutes the basis ofthe new paint : the remainder , consisting of iron or copper , with a portion of sulphur , is to be washed in warm water , and the water set to evaporate by the heat of the sun , or in a trough upon the kiln : when the liquor is thus brought to a sufficient degree of concentration , crystals will be deposited of green or blue vitriol .
AIR . On the 14 th of August , at 7 o ' clock in the evening , Cit . Garnerin and Cit . Beauvais ascended in a balloon from the garden d'Apollon , at Paris . At the height of nearl y 400 toises Cit .

Moiilins , quitted Cit . Garnerin , who departed at half past three in the morning to complete his aerial voyage , by taking a long flight . Cit . Frederic Humboldt , a celebrated philosopher , had begged Cit . Garnerin to fill with air a small flask with a ground stopper . Cit . Garnerin emptied the water which it contained at the heig ht of 66 9 toises ( 1303 metres ) above Paris . Cit . Beauvais brought back the bottle , filled with atmospheric air , to Cit .
