200 Miscellanies. 



31. Recipe for the beverage called imperial pop. — Put into an 

 earthen pot two pounds of sugar, two lemons cut into slices, and two 

 ounces of cream of tartar. Add nine quarts of boiling water, mix 

 the materials well, cover the vessel with a stout cloth and let it cool. 



When cold, spread two table spoons full of good yeast from beer 

 on a thin slice of bread and put into the vessel, which must be cov- 

 ered as before, and left till the next day. It may then be filtered 

 through a fine cloth, and botried and corked tight in strong bottles. 

 In the course of three or four days the fermentation will be nearly 

 complete, and the liquor may be drunk. — Jour. Con. Us. 



3^. Heat by phosphorus and iodine. — Prof. Cesar Gazzaniga has 

 proved that the combustion produced by the contact of these two 

 substances is not prevented by a very great reduction of tempera- 

 ture of the materials before contact. This is manifest by placing 

 the phosphorus and iodine on a thin glass and putting this in a freez- 

 ing mixture, and as soon as they have acquired the temperature, in- 

 corporating them by mixture, when inflammation always take place, 

 although the temperature may be 24° R. below zero. With two 

 grains of phosphorus and three of iodine, the flame continued nearly 

 fifteen minutes. — Bib. Univ.

 shortly be published by Hezekiah Howe & Co.
