ON A COMPOUND OF ALBUMIN WITH PHENOL. 509 



I prepared the compound several times and always observed 

 essentially the same properties. 



As it appeared to me of some interest to test whether this 

 product would show, in the absence of air, antiseptic properties on 

 account of the introduction of phenyl groups, I dissolved 1 grm. 

 :n potassium hydroxide solution of 1 per cent and added dilute 

 acetic acid until a precipitate commenced to be formed, diluted 

 to ioocc, and infected the solution from putrified meat. The 

 filled flask was provided with a stopper, carrying a U-tube con- 

 taining some mercury to exclude the air. 



After seven weeks standing at the ordinary temperature, 

 the liquid appeared turbid and contained a flocculent sediment. 



Upon opening a putrid smell was noticed and the microscope 

 revealed a rich bacterial vegetation. 



Triphenylalbumin is therefore a good nutrient for microbes 

 and is subject to fermentation like the ordinary albumin.
