Gentleman'! Magazine. Professor Mantegazzi found that neai'ly all the essences used in perfumery, and many others not appropriated by the perf umer, when exposed to the air and light develop ozone. He says that "the oxidation of these essences is one of the mo3t conveuient means oí producing ozone. s nee, even when in a verv minute quaütity, they eau ozonize alarge quantity of oxvgen. wh.le their action ís very persistent; that in the greater nuinber of essences, in order, to deveiop ozone, roquirethc direct rays of the sun; in a small immber ol cases they etlect the chauge with diffnsed light; in few or none in darkness." Even u ressel that has befen perfumed with au essence and afterwards washed aud dried, stil develops ozone, provided a élight odor remains. The most effective essences are those of cherr', laurel, palma rosa, clores, lavender, mint.junipbr, lemona, fennel and bergamot; the los;; eíiective are an:se, nut rne, eajegut and thyme. Mantegazzi add lliat' "eamphor, as an ozonogenic agent, is inferior to any of the abovo named essences." TI ese faets should be betterknown than tliey are. Our grandmol hers used perfumes as disinfectants, and ozone bene; the most eífective of oxidiiíing disinfectants it appcars that they right lu the east, where there is nmeh need for atmospherio purificafon, the old faith in perfumes st 11 remains. With us it is now generally suppoed that such perfumes mercly hide the malodor, and decsive us, lat if fantegazzi and Dr. Anders are right this modern notion is afallacy.
