The second chloride above mentioned unites also with platinous 
chloride to form a part which crystallizes in very brilliant, thin,

UTZENBERGER has continued his investigations of the very 
temarkable compounds of platinous chloride, and has arrived at 
Mteresting results, When the compound, P(C,H,0),F° Cle, is 
treated with ammonia, it becomes fiuid and gradually dissolves. 
The solution gives on evaporation the chlorhydrate of a new base,
