There is also another composition of suffumigants (suffimentorum) for warding off diseases, but more expensive and, it is thought, more effective:

bearsfoot, 6 ounces
galbanum, 1 pound
Castoreum, half a pound

stag horn,—
“male” jet stone, —
“female” jet stone, 3 ounces each
haematite stone, 2 ounces,
magnet (sideritis) stone,—
argyritis (silver dross/litharge) stone, 1 ounce each
“sea-tails” (caudas marinas),—
sea snakes (ungues marinos), to the number of 7 each

deer marrow,—
