PARAFFIM3I. 
Paraffin. 
A mixture of solid liYdrocarbous. chiefly of the methane series. 
The paraflin of the U. S. Pharmacopceia melts between 51.6^ and 57.2^ 
C. The **hard paraflin” (Parafiinum Durum) of the British Pharma- 
copceia melts between 54.4" and 57.2" C., while the “Paraffinum 
solidurn” of the German Pharmacopceia melts between 74- and 80- C. 
pelletierina: taxnas. 
Pelletierine Tannate. 
•*A mixture in varying proportions of the tannates of four alka- 
loids (punicine. iso-punicine. methyl-punicine. and pseudo-punicine) 
obtained from Punka gmnatum'' (Pomegranate). Also known as 
puniciuum tannicum. The alkaloids are also known as pelletierine. 
iso-pelletierine; etc. 
Character. — A yellowish-white, odorless, amorphous powder, hav- 
ing an astringent taste, and a weak acid reaction. 
Solubility. — Soluble in water (1:235). alcohol (1:12.6). and in warm 
dilute acids. 
Dose. — “Average dose: 0.250 Gm. =250 milligrammes (4 grains).” 
(P. S. P.) 
The pelletierines of commerce seem to vary greatly: some are ten 
times as poisonous as others. While the U. S. Pharmacopceia names, 
as the average dose of the tannate. 0.25 Gm.. some writers recom- 
mend 0.75 to 1.5 Gm. Very unpleasant effects are said to have 
resulted from 0.4 to 0.5 Gm. 
PETROLITOI ALBl 31. 
White Petrolatum. 
“A white unctuous mass of about the consistency of an ointment.” 
it is puritied petrolatum and is used in the preparation of the Oint- 
ment of Boric Acid, the Ointment of Phenol (Unguentum Acidi Car- 
bolic!. U. S. P.. 1890). etc. 
PHEXOL LIOrEFACTTlI. 
Liquefied Phenol. 
Practically the Acidum Carbolicum Licpiefactum of the British and 
German Pharmacopoeias. It is prepared from Phenol (Acidum Carboli- 
cum. U. 8. P.. 1890) by the addition of distilled water in the propor- 
tion of 1 Gm. of the latter to 9 Gm. of Phenol. The U. S. Pharma- 
copoeia Phenol must contain not less than 96 per cent of absolute 
phenol: whereas this preparation. Phenol Liquefactum. contains not 
less than 86.4 per cent, by weight, of absolute phenol and about 13.6
