Toavoid this, matters fhould be managed in fuch a man-ner, that, without feniibly interrupting the operationthe vapour may iffue from the diftilling velfel gra-dually, and without fudden explofions : by whichmeans the water will imbibe as fait as the velfel diftilsfor a certain time ; and in order to preferve all thevapour, there ought to be feveral receivers, one abovethe other, communicating by pipes, that the vapourwhich does not condenfe in one may do fo in the following apparatus may be ufed with fuc-cefs :. i.
