prefence of the alcohol, which evaporates very foon after it 

 has been applied. 



When ufed to join broken glafs or china, the pieces to be 

 joined Ihould be prcvioufly warmed. Immerfion in hot water 

 will give them a fufficient degree of heat. Wipe off the 

 water before applying the cement, which may be laid on 

 with a pencil : then prefs the pieces together, binding ihem 

 with a firing or a bit of foft wire if neccflary. 



XII. JapaneJ'c Cement, or Rice Glue. 



This elegant cement is made by mixing rice flour inti- 

 mately with cold waier, and then gently boiling it. It is 

 beautifully white, and dries almoft tranfparent. Papers 

 pafted together by means of this cement will fooner fepa- 

 rate in their own fubftance than at the joining, which makes 

 it extremely ufeful in the preparation of curious paper arti- 

 cles, as tea-trays, ladies' drefling boxes, and other articles 

 which require layers of paper to be cemented together. Tt 

 is in every refpeft preferable to common pafte made with 

 wheat flour for almoft every purpofe to which that article 

 is ufually applied. It anfwers well, in particular, for patting 

 into books the copies of writings taken oft' by copying ma- 

 chines on unfized filver paper. 



With this compofition, made with a comparatively fmall 

 quantity of water, that it may have a confiftcncc fimilar to 

 plaftic clay, models, bufts, ftatues, baflb-relievos, and the 

 like, may be formed. When dry, the articles made of it 

 are fufceptible of a high polifli : they are alfo very durable. 



The Japanefe make quadrille-fifli of this fubftance, which 

 fo nearly refemble thofe made of mother-of-pearl, that the 

 oflicers of our Eaft Iiidiamen are often impoled upon. 



XIII. Glue of the Laplanders. 



The bows of the Laplanders are compofed of two pieces 

 of wood glued together; one of them of birch, which is 

 flexible, and the other of fir of the marflies, which is ftift", in 

 order that the bow when bent may not break, and that when 

 unbent it mav not bend. When ihefe two pieces of wood 

 are bent, all the points of contact endeavour to dii'unite them- 

 felves, and to prevent this the Laplanders employ the fol- 

 lowing. cement : — They take the fkins of the largeft perches *, 

 and, having dried them, moiften them in cold water until 

 they are lb foft that they may be freed from the fcales, which 

 they throw away. They then put four or five of thefe fkins 

 in a rein-deer's bladder, or they wrap them up in the foft
