hydroxid, rediiced the Fehling-Benedict reagent. This result, with 

 the precipitation by ammonia, seemed to show the presence of both 

 glucoprotein and histon in the precipitate. 



When alcohol Solutions of ovo-mucoid and histon hydrochlorid 

 were poured together, a precipitate formed at once that gave both 

 the ammonia test and the reduction test. The latter process is the 

 simplest and quiekest method of obtaining this product. 



The results of these researches have shown that the methods for 

 the preparation of histon, as outlined in the literature, are in serious 

 need of revision. In fact, the results suggest that so-called histon 

 is a protein salt rather than a simple protein. In a future paper will 

 be presented the findings in regard to histon preparation.
