curious and most important of all the 
phenomena produced by the boracic ra- 
dical when placed in contact with other 
‘bodies, are those that it presents with 
oxygen. When four grains and a half of

oxygen, and the whole placed over quick- 
silver, a mest rapid “combustion took 
place, and the quicksilver rose to about 
the middle of the jar. The boracic ra- 
dical exhibits the same phenomena with 
air as with oxygen, only: that: the com- 
bustion is less rapid. Hence it follows, 
that the boracicacid is composed of oxy- 
gen, and a combustible body: and that 
this substance is of a peculiar nature, and 
ought to be classed with phosphorus, 
carbon, and sulphur. ‘It requires a great 
~quantity of oxygen to change it into 
boracie acid, and it previously passes into 
the state of a. black oxyde.
