GLUCINA. 321 



This mean of 3-2522 must be exceedingly near 

 the truth ; as near, probably, as it is possible to 

 come with our present analytical means by a 

 direct analysis. I consider myself entitled to 

 conclude from it, that the true atomic weight 

 of glucina is 3*25. I leave out the two last deci- 

 mal places, because they would destroy the law 

 pointed out by Dr. Prout, which we have seen 

 to hold in all the other atomic weights of 

 bodies; namely, that these weights are all 

 multiples of 0*125, the atomic weight of hy- 

 drogen. 



2. Berzelius likewise analyzed the muriate of 

 glucina ; and, although the muriates are not so 

 easily analyzed with accuracy as the sulphates, 

 it will be well worth our while to state the re- 

 sult of the analysis as constituting an exceedingly 

 good approximation. The bimuriate of glucina 

 was a crystallizable salt : but when the excess of 

 acid was expelled, he obtained only a gummy 

 like mass. This matter was dissolved in water, 

 the solution filtered, and the glucina was thrown 

 down by carbonate of ammonia, and the muria- 

 tic acid by nitrate of silver. The glucina weighed 

 0-626, and the chloride of silver 3-392, which is 

 equivalent to 0-85962 of muriatic acid. Accord- 

 ing to this analysis, muriate of glucina is com- 

 posed of
