4. OJ Stanh prepared from, the Fruit cf the JEJculus 



PwDia, or Horje Chcjlnut. 



In the 29th number of the Repertory of Arts, there is an 

 Account of a patent, obtained bv Lf)rd William Miirrav, for 

 making Itarch from the fruit of the refculus hippocafianuni. 

 A writer in the London Monthly Magazine for 1798 fays, 

 he has repeatedly, and in various svavs, endeavoured to make 

 ftarch of the fruit, but always uni'uccefsfully ; for it turns to 

 a vellow colour. 



The fruit of our cnfculus pavla is much larger than that of 

 the a^fculus hippocaltanum, and is of a white colour : that of 

 the hippocaltanum is yellow. 



A fingle nut, dried, weitihed half an ounce and twenty-five 

 grains, and yielded forty-four grams of line ftarrh. 



I prepared half a pound of this ftarch from the nuts of the 

 sefculus pavia, and have kept it two years, and the white co- 

 lour is no way impaired. It is fupcrior to the fineft Poland 

 ftarch, and has been ufed, by feveral ladies, to (tarch various 

 articles ot drels, without imparting any yellow colour to 

 them. 



The method of preparing it is, to take off the fiiells from 

 the nuts with a knife ; grate them in a veflel of water which 

 will hold the tine particles of the ftarch fufpended ; when they 

 are to be decanted inio another vefll:!, which muft remain at 

 reft until the ftarch fublides to the botiom. The water is 

 then to be poured otT, and frelh is to bo added, and the Itarch 

 is to be well ftirred about in it; when it n)uft be again per- 

 mitted to fubfide. The water is then to be thrown away, 

 and the ftarch is to be dried in the hm. 



The water of the lirlt waihing holds a poifonous matter 

 in folution, which, when evaporated to the confiftencc of an 

 extra6l, and mixed with dough, will intoxicate and fweil tlie 

 bellies of fmall tlfties.
