be obtained with great difficulty. — Analytical Xotes for 1906, 190T, '< 
pp. 21, 22. 
Francis, John M., reports that TO per cent of the jalap examined 
by him was above 8 per cent, while the remaining 30 per cent con- 
tained less than 6 per cent of resin. The highest resin content was 
10.5 per cent. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 338. 
Patch. E. L., reports one lot of jalap which contained 11.43 per 
cent of resin. — Ibid., v. 54, p. 338. 
Hankey, William T., reports examining 8 lots of jalap which 
ranged from 6.42 to 13.36 per cent of total resins and from 0.92 to 
2.35 per cent of resins soluble in ether. — Am. Druggist, X. Y., 1906, 
v. 49, p. 361. 
Ohliger, Willard, did not find a sample that would pass muster. —

KAOLINUM. 
Francis, John M., advises purchase by sample, as only by experi- 
mentation will the pharmacists learn just what is right. — Bull. 
Pharm. Detroit, 1906, v. 20, p. 56. 
A contributor to the “ Miscellany ” column, calls attention to 
Stump f’s use of clay internally and externally against various bac- 
teria, the theory being that the bacteria are inclosed in the clay and 
“ buried alive,” as it were. — J. Am. M. Ass., 1906, v. 47, p. 2113. 
KINO. 
Francis, John M., says the official tests are not sufficient to protect 
the buyer of kino from sophistication and substitution. Much of the 
kino sold is Australian kino, red gum, or eucalyptus kino * * *, 
which while similar to the official in physical and therapeutic proper- 
ties has not, in solution, the tendency to gelatinize, which is such a 
marked characteristic of the latter. He thinks Marshall’s process 
is worth testing out. — Bull. Pharm. Detroit, 1906, v. 20, p. 56. 
The Ph. Brit. Committee of Deference in Pharmacy reports that 
the solubility of kino is a matter for investigation. — Chem. & Drug., 
Bond., 1906, v. 69, p. 864. 
Evans Sons Lescher and Webb, found two samples of kino to be 
83 per cent soluble in boiling water. — Analytical Xotes for 1906, 
1907, p. 23. 
Cline, R. R. D., points out that the gelatinizing of kino prepara- 
tions is probably due to the presence of an enzyme, and suggests ob- 
viating this gelatinization by fractional sterilization. — Proc. Texas 
Pharm. Ass., 1906, p. 16. 
Wilbert, M. I., asserts that a sample of tincture of kino made by j 
a process similar to that given in the U. S. P. VIII was still fluid
