den nederste Glaskugle slutter godt, vil den gjennem a 
passerende Luft spaltes i en Mængde meget fine Blærer, 
som ved at stige op inellem de afBarytvand omgivne Glas- 
kugler bliver fuldstændig kulsyreiri. Det uformige Kor 0

may be immersed in baryta water. Now. assuming the 
large glass ball to fit well, the air will pass a in the form 
of minute bubbles, which, having to ascend between the 
glass balls surrounded by baryta water, must part with the 
|| whole of its carbonic acid. The tube 0 contains baryta 
j water; H leads to the aspirator. 
Den af Classen foreslaaede Kjøler virker saa udmær- 
ketf. at man i meget laug Tid kan koge fortyndet Saltsyre 
i Kolben, uden at det mindste Spor af Chlor kan paavises 
i Forlaget, fprudsat at den gjennemlcdede Luftstrøm ikke 
gives for stor Hastighed, kvad der imidlertid heller ikke er 
fornødent. 
The cooler devised by Glassen is so excellent, that 
diluted hydrochloric acid may be boiled in the matrass for 
a very considerable length of time without a trace of acid 
being detected in the receiver, provided that too great 
rapidity be not given- to the current of air; this, however-, 
is quite unnecessary.
