Oil. The Weight of the black Subftance, that remain- 
ed behind in the Retort, was ten Ounces, one Drachm 
and an Half ; which after Calcination for twenty 
Hours, when it gave over fmoking, left one Ounce 
and five Drachms of reddifti brown Afhes ; from 
which were got fix Drachms and twelve Grains of 
lixivial fixt Salt merely alkaline. 
The Lofs of Parts in B. V. was four Drachms 
and twenty four Grains. In Diftillation from the 
Retort four Ounces, and in Calcination eight Ounces, 
four Drachms and thirty fix Grains went off in 
Flame and Smoke. 
Further, the Pulp of Cafiia eafily grows four ; 
and being diluted with Water, and put up into a 
Cafk for feveral Months, lets fall an efiential Salt 
perfe&ly refembling Cream of Tartar. 
By this Analyfis then it appears, that in the Pulp 
of Cafiia is contained a fine volatile acid Salt, 
which rifes the firfl in Diftillation ♦, and another 
which is more fixed, requiring a ftrong Fire to force 
it over along with the Oil. With thefe are found 
a very little urinous Salt, and a middling Portion 
of Earth. Wherefore its Virtues are owing to a 
certain efiential Salt like Cream of Tartar, but finer 
or lefs enveloped with Earth, and more tempered 
with fmooth oily Particles. 
Moft Phyficians agree that Cafiia is a mild and 
harmlefs Purgative, fuitable to all Perfons, of what- 
ever Age, Sex, or Temperament •, as likewife to 
pregnant and Child-bed Women. Upon the Dif- 
covery of the Gentlenefs of this, and other folu- 
tive Medicines, the Arabians became bolder in the 
Practice of Purging, than the ancient Greeks , who 
were accuftomed to ufe only the more violent Ca- 
tharticks. It is advantageoufiy preferibed in ar- 
dent and inflammatory Fevers, in Affedtions of the
