tion of acetic and butyric acids. When oxychlorid of phosphorus, 
PCls Oz, is brought into contact with valerianate of potash, a violent 
reaction takes place and the odor of the oxychlorid disappears. By 
treating the mass with a weak solution of carbonate of potash, and then 
with ether, and evaporating the etherial solution, the anhydrous acidis 
obtained as a limpid, highly mobile liquid, lighter than water, and pos 
sessing a feeble odor of apples. The liquid boils at 215°, and distills 
over perfectly colorless: its vapor irritates the eyes and provokes 
coughing. The reaction by which the anhydrous yalerianic acid is 
obtained, is represented by the equations, ai
