it will be perceived I have lessened the number 
of classes in Murray’s arrangement by four as- 
semblages. His is the simplest arrangement, and 
contains fewer classes than any systematic classifi- 
cation, except Darwin’s, with the principles of 
which I cannot accord. I have added five classes: 
Aromatics—Sedatives,—Salivant Masticatories,— 
Topical refrigerants—and Pustulating irritants. 
I have expunged, Expectorants—Refrigerants,— _ 
Emmenagogues and Demulcents; and I have assu- 
med the class of Antilithics in lieu of Lithontrip- 
tics. With this modification of twenty-three instead - 
of twenty-two classes, I leave the subject ofclas- = 
sification of medicaments to proceed to notice 
what 1 shall denominate * Adventitious therapeu- 
tic agents, not medicaments ; in the proper sense 
of the word, and to this assemblage I deem pro- 
_ per to refer Emollients, Epispastics, Escarotics 
and Demulcents, of Murray’s scheme—modifying — 
this latter class, into Local Demulcents. This — 
will reduce the twenty-three classes retained and 
proposed—to fifteen of true medicaments, “The = 
following scheme will exhibit the points of the 
recapitulation, and the anticipatory yiew of the 
adventitious remedies.
