Butyric Alcohol.—Among the chemical facts brought forward at the 
Academy the past month, we notice the discovery of butyric alcohol 
by M. Adolph Wurtz. This alcohol, (CsHs)O, HO, which bas been 
detected by M. Wurtz in the caput mortuum of the oil of potatoes, $0

these points, we may believe that the present condition of analytical 
chemistry is not so bad that the method of Deville has much to chang® 
in its processes. ne
