 15 inches. The margin of ebbing tide gra- 

 dually grew wider on both sides of the river 

 till it covered the whole river. The water at 

 each point was not at rest more than 3"™.

 waters along shore; having sunk about 3

CANNIZAKO found that hydruret of benzoyle, Ci^ H« 0^, was 

 converted by the action of an alcoholic solution of potash 

 into benzoic acid, C^'* H^' O'*, and the alcohol corresponding to it, 

 Qi4jj8Q2^ According to Cannizaro and Bertagnini*, the hy- 

 druret of anisyle undergoes, under the same circumstances, a 

 like change, being converted into anisic acid, C^^ H^ 0®, and into 

 an alcohol corresponding thereto, C^^H^^O'*, anisic alcohol. 



Anisic alcohol distils without decomposition at 250°, and melts 

 at 23°. It crystallizes in hard, white, brilliant needles. By 

 oxidizing agents, and also when left in the air in contact with 

 platinum black, it is converted first into hydruret of anisyle, and 

 then into anisic acid. Anisic alcohol, when warm, dissolves several 

 salts, as benzoate and acetate of potash ; and organic substances, 

 as salicine, hippuric acid ; on cooling, these crystallize out. With 

 potassium it forms a compound, hydrogen being liberated; treated 

 with hydrochloric acid gas, a body is obtained which appears to 

 be the chlorine compound of the radical contained in the anisic 

 alcohol. 



The same chemists endeavoured to produce from hydruret of 

 salicyle (salicylous acid), C^'^H^'O'*, the corresponding alcohol, 

 but without success. 



Casselmannt makes some interesting contributions to our 

 knowledge of the oxy chlorides. It was his object, in investi- 

 gating these bodies, to endeavour to replace the oxygen con- 

 tained in them by chlorine ; and as the chloride of phosphorus,
