An answer in “ Queries and Minor Votes ” disclaims any confidence 
in the trypsin treatment of cancer, but discusses available forms. — 
J. Am. M. Ass., 1906, v. 47, p. 450. 
Additional references on the use of pancreatin and its constituents 
will be found in the Index Medicus and the J. Am. M. Ass. 
PAEAFFINUM. 
Francis, John M., calls attention to the fact that commercial 
paraffin varies much more widely than is indicated by the pharma- 
copoeial melting points, and recommends that in ordering the melt- 
ing point be specified, to save both vexation and money. — Bull. 
Pharm., Detroit, 1906, v. 20, p. 142. 
Fisher, Th., discusses the methods proposed for determining the 
congealing point of paraffin and outlines a method which depends 
on noting the degree of temperature at which the thermometer will 
stand for at least ten minutes. The necessary apparatus is figured. — 
Ztschr. f. ang. Chem., Berl., 1906, v. 19, part 2, pp. 1323-1326. 
The Ph. Brit. Committee of Deference in Pharmacy reports that 
the melting point of paraffin should be 50° to 55° C. — Chem. & Drug., 
Lond., 1906, v. 69, p. 864. 
MacFaclden, W. Lester, says that paraffin and its near relative, 
ceresin, have the rare grace of stability. They are neutral, simple 
in composition, and do not take part in destructive interreactions. 
Therapeutically, nothing more than protection can be expected of 
them, absorption being nil. Their sole office is to harden protective 
applications.— Bull. Pharm., Detroit, 1906, v. 20, p. 203. 
Kirschner, J., (Virchows Arch., 182, H. 3) discusses the destiny 
of paraffin that has been injected into the cellular structures, and the 
structural changes produced. — Biophysik. Centralbl., Leipz., 1906, 
v. 1, p. 227. 
Additional references on the use of paraffin will be found in the 
Index Medicus and the J. Am. M. Ass. 
PARALDEHYDUM. 
Broadbent, AY., (Practitioner, Bond., July) states that paraldehyde 
or chloral is preferable to sulfonal, trional, or monal in the sleepless- 
ness of the young. — J. Am. M. Ass., 1906, v. 47, p. 463. 
PAREIRA. 
Scholtz, M., contributes a further study on the alkaloids of com- 
mercial pareira. — Arch. d. Pharm., Berl., 1906, v. 244, pp. 555-560. 
The Ph. Brit. Committee of Reference in Pharmacy assert that 
pareira will probably be omitted. — Chem. & Drug., Lond., 1906, v. 69, 
p. 864.
