potassa ; a solid substance is rapidly formed, which floats upon the 

 surface of the solution, and which is nothing but the same sinapoline, 

 whilst a strongly alkaline liquid passes into the receiver, which is a 

 mixture^of several bases, in which we have traced already 



(1) Methylamine. 



(2) Propylamine. 



(3) Acrylamine. 



The latter substance boils between 180 and 190. All our at- 

 tempts to produce a well-crystallized platinum-salt of this base have 

 hitherto failed. 



The experiments detailed in the preceding sketch incontestably 

 demonstrate the existence of a new series of alcohols, the third term 

 of which is acrylic alcohol. 



Like ordinary alcohol, this new alcohol furnishes a series of deriva- 

 tives, which may be formulated in a similar manner. 



The following tables exhibit the terms of the acryl series hitherto 

 prepared in juxtaposition with the corresponding members of the 

 ethyl series :
