it is possible, radicals of higher equivalence are thus produced. 
With these facts premised, I pass to the subject of the 
present paper ; i.e¢., the consideration of the bodies which re- 
sult from the union of the monad compound radical hydryl 
(HO)’ with the simple radicals. Representing H,O by @-O-@, 
hydryl is @—@)-, which may be represented either by a larger 
} circle or by the letters alone, thus Ho-. From the principles

A reply to this question becomes possible only by classifying

negative, according to the quality of this combining power. 
When a positive miple radical combines with hydryl, a base
