rated to dryness, and the product was subjected to the action of 

 aether mixed with a fifth of rectified alcohol. 



The liquid, treated with excess of carbonate of lime, was left in 

 contact in the cold with alcohol. Hot distilled water was afterwards 

 shaken with the undissolved residue, and after having been filtered, 

 evaporation was carefully conducted. The product of this last ope- 

 ration was a soluble salt, which crystallized on standing, and pos- 

 sessed all the well-known characters of lactate of lime. If excess 

 of nitric acid be used instead of oxalic acid, oxalate of lime is obtained 

 instead of lactate, for the nitric acid converts the lactic into oxalic 

 acid. 



MM. Cap and Henry observe, that it appears to them evidently to 

 result from the preceding experiments, that after having separated 

 the microcosmic salt from the evaporated urine, and saturated the 

 lactic and phosphoric acid in excess, and having obtained a crystal- 

 lized product by the intervention of alcoholized aether, in which pro- 

 duct M. Lecanu admitted the presence of lactic acid and urea ; that 

 these crystals have the form and characters very distinct from those 

 which belong to pure urea, and that they perfectly resemble those 

 procured by the direct action of lactic acid on urea ; lastly, that 

 the hydrates of zinc, barytes, lime and oxalic acid, occasion in these 

 crystals the production of lactates of zinc, barytes and lime, and 

 separate lactic acid ; they observe that it is impossible to demon- 

 strate in a more direct manner the existence of a compound of these 

 two principles. — Journal de Pharmacie, xxvii. 356.
