By analogous processes, there can be little doubt that many new series of organic 
acids may be derived from inorganic acids, by the replacement of one or more atoms of 
oxygen by an alcohol radical ; in fact, my pupil Mr. Hob.sox is now studying a new 
series containing sulphur, produced by the action of zincetbyl and its homologues upon 
sulphurous acid: the ethyl acid of this series is formed by the replacement of one 
equivalent of oxygen, in three equivalents of sulphurous acid, by an alcohol radical. 
The foUovring Table exhibits the compounds of the new series of acids, which have 
been described in the foregoing pages.
