■ In a chymical Anatsfu , two Pounds of Frank- 
incenfe yielded feven • Ounces, feven, Drachms and 
twenty four Grains of acid Phlegm, which was 
fo.mewhat auftere, odorous, and reddifh . then one 
Ounce, two Drachms and forty fix Grains of 
Phlegm, as well acid, as urinous, and of a red 
Colour *, afterwards one Ounce,, two Drachms and 
•.twenty four Grains, of tranfparent, fluid, yellow- 
ifh and fragrant Oil ; five Ounces and three Drachms 
of thick brown Oil •, with fix Ounces, five Drachms 
and thirty Grains of thicker Oil of the Confidence 
of Honey. The black Mafs remaining in the Re* 
tort weighed five Ounces, fix Drachms and forty 
three Grains, which being calcined for fifteen Hours 
in a Crucible, became of a reddifh Colour, and 
left one Ounce, three Drachms and fix Grains : 
From thefe were got by Lixiviation twenty two 
Grains of fixt alkaline Salt. The Lofs of Parts 
in Didillation was four Ounces, three Drachms 
and twenty nine Grains •, and in Calcination four 
. Ounces, four Drachms and thirty feven Grains. 
Hence it appears that there is a larger Proportion 
of Earth, and fomewhat more of an ammoniacal 
Salt in Frankincenfe than in Maftich ; and that the 
faline and oily Parts are more intimately combined. 
It is recommended internally for many Difor- 
ders of the Head and Bread, in Fluxes of the 
.Womb and Belly ; in Coughs, fpitting of Blood, 
Loofenefles, and Dyfenteries ; for it foftens and 
obtunds the Acrimony of the Humours, efpecially 
the Lymph when overdocked with faline Particles. „ 
The Dofe is from 9j. to. zj. or gij. It is reckoned 
a Angular Specifick againd a Pleurify, and in par-
