It will bs seen that Personne's numbers vary rather widely, but 

 fall for the most part between those obtained by us for our two 

 alcohols. It will also be seen that the formula he has proposed, as 

 agreeing best with the mean of his analyses, is that of a homologue 

 of our alcohols, the general expression being 0^ Hgu.ß 0. As he 

 worked upon bird-lime from a species of Ilex different from that 

 which yields Japanese bird-lime, it cannot for the present be decided 

 whether ilicic alcohol is distinct from the alcohols here described. 



The resin Old component of bird-lime. 



The resinoïd l)ody is obtained in pale-yellow fragments which 

 are brittle, and not sticky like bird-lime. It melts at 110°, and does 

 not volatilise when heated to 220° in a vacuum. Above 360° it 

 darkens, boils, and distils without much apparent change. It is very 

 soluble in spirit, even of only 80 ^o strengtli, also in ether. When 

 its spirit solution is evaporated by heat sufficiently, it separates from 

 its solvent as a viscid liquid still containing spirit, which evaporates 

 by further heating below 100°. Its solubility in spirit is not in- 

 creased by the presence of potassium hydroxide. Heated with the 

 solid hydroxide barely to the melting point, it slowly combines with 

 it, probably at the same time absorbing oxygen. The cooled mass 

 wholly dissolves in water from which hydrochloric acid precipitates 

 a gelatinous body very brittle when dried. We have not farther 

 examined it, ïov want of material.
