 I kept moiftened alumine a long time In contaa with at- 

 mofphcric air and with oxygen gas, without obfervmg the 

 leaft abforption. A chemift having related that the ablorp- 

 tion took place by the means of agitation, agitation was em- 

 ployed with much patience, but the refult was the fame. 

 The operation was repeated with white clay which had been 

 fent to me by Giivton, but fliU without abforption. This 

 anril, however, expofcd to a ftrong heat, gave a little car- 

 bo'nic acid and a fmall quantity of carbonated hydrogen gas. 



VI. Defer iption of aii improi'ed Apparatus for DifiUing, hy 

 which a confidtrable Saving may be made in the Article of 

 Fuel; and of an Apparatus for the Reaification of Sprit 

 of Wine. By J. W. C. Fischer*. 



X HE following apparatus. If not entirely new, is at- 

 tended with fuch "confiderable advantage in regard to the 

 faving of fuel, as muft be acknowledged by every impartial 

 and c°ompetent judge. The principal improvements may be 

 found in Gottling's Pocket-book t for Chemills and Apo- 

 thecaries, 1798; but, as far as I know, little or no ufe has 

 hitherto been made of them. The reafon of this may be, 

 that the above work comes very feldom into the hands of 

 thofe who have mod occafion to make ufe of it. Diftillers 

 by profeflion continue, for the moft part, thofe modes of 

 operation which they have been taught in learning then- bu- 

 finefs, partly bccaufe they have no real opportunity of intro- 



* From Journal fur Fabrik, ManHfaBur, &c. December 1799- 

 t According to the aboye pocket-book, this dillilling apparatus was 

 firft nude in'Denmark, where it has been ufed above fifty timeb on a large 

 fcalc in one of the diftilleries. The pcrfon who employed it got the firft 

 idci of it from a DaniflV journal, the author of which bad copied it from 

 a German work entitled Auferlefine Sarnmltoig Odionomifcb.r Sdmftcn, 

 Drefden .7-;=. The whole apparatus, the cooler excepted, coft in Den- 

 mark, where every thing is dearer than in Germany, no moic than 17 

 or iX rix-dollars ; whereas a l.rL'C ftiU wo^ild co(t from four to five hur- 

 dr d rix-doli.rc. An apparatus which can be purchafcd at lb cheap a 

 rati, and by which one half is favcd in the article of fuel, muft no doubt 

 be o"^ importance lu tliofe wh.o n'.ay have occifiua to employ it.
