(3.) Meconiate of Ammonia.—Crystallizes in star-form needles, 
which, when sublimed, lose their water of crystallization, and 
assume the shape of scales. The crystals are soluble in ly their

If two parts of sal ammoniac be triturated with three parts of 
meconiate of barytes, and heat be applied to’ the mixture, meco- 
niate of ammonia is sublimed, and muriaté of barytes remains. 
(4.) Meconiate of Lime—Crystallizes im prisms. Soluble 20 
eight times its weight of water. Its constituents are,

Choulant not having succeeded in obtaining meconiate) of 
barytes in crystals, did not attempt to analyze it. 
XII. On the Equivalent Number for Mecouic Aced- 
The numbers annexed to the analyses of Choulant, represent 
the equivalent numbers for the bases and meconic acid uy éach 
analysis. We see from them that the results obtained by this 
chemist are far from correct; for the equivalent number for 
meconic acid varies in each analysis. These numbers are a 
follows :

The mean deduced! from: these four salts gives us 2-714 for 
the weight of an atom of meconic acid. The number 2-75, 
therefore, may be considered as an approximation ; but probably 
not a very near one. 2°75 represents the weight of an atom of 
carbonic acid. But it would be premature to speculate on this 
subject till we are in possession of;more accurate analyses of the 
meconiates.
