Francis, John M., notes that a slightly greater latitude as regards 
purity is allowed in connection with lithium salts. — Bull. Pharm., 
Detroit, 1906, v. 20, p. 98. 
LITHII CARBONAS. 
The Ph. Brit. Committee of Eeferenee in Pharmacy report on 
lithium carbonate savs the analytical data actually work out to 99.5 
per cent, and not 98.5 per cent ; this standard is difficult to attain. 
A volumetric test, as in the U. S. P., would be better. — Chem. and 
Drug., Loncl., 1906, v. 69. p. 864. 
Caspari, Chas. E., reports 5 samples of lithium carbonate exam- 
ined — 2 U. S. P., 1 contained excess of other alkalis, and 2 contained 
metallic impurities. — Proc. Missouri Pharm. Ass., 1906, p. 99. 
Smith. Kline & French Co. report that all of 4 samples of lithium 
carbonate examined were of excellent quality. — Lab. Kep., S. K. & F., 
1906, p. 18. 
LITHII CITRAS. 
The Ph. Brit. Committee of Reference in Pharmacy report on 
lithium citrate says the loss of weight stated to occur at 115.5° C. is 
incorrect. The last portions of water are removed only at about 140° 
C. The formula should be Li 3 C 6 H 5 0 7 .5H 2 0, which loses 24 per cent 
at 95-100° C. — Chem. & Drug., Lond., 1906, v. 69, p. 864. 
The report of the Committee on Drug Adulteration says that 
lithium citrate dried at 100° C. gave from 85 to 89 per cent lithium 
citrate by the pharmacopceial test. It is claimed that a higher degree 
of heat should be used to make the salt anhydrous; not less than 120° 
C. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 339. 
Caspari, Chas. E., reports 3 samples examined. Two contained 
metallic impurities, 1 free alkali. — Proc, Missouri Pharm. Ass., 1906, 
p. 102. 
LITHII SALICYLAS. 
Caspari, Chas. E., reports 7 samples of lithium salicylate exam- 
ined — 4 U. S. P., 1 contained excess of other alkalis, and 2 metallic 
impurities. — Proc. Missouri Pharm. Ass., 1906, p. 99. 
LOBELIA. 
Henkel, Alice, mentions Lobelia inflata L ., commonly known as 
lobelia, Indian tobacco, gagroot, vomitwort, and bladderpod, as being 
found in dry soil, fields, old pastures, and along roadsides from 
Canada to Georgia, Nebraska, and Arkansas. — Bull. Bur. Plant. Ind., 
U. S. Dept, Agric., 1906, No. 89, p. 44. 
Naylor, W. A. H., reviews the chemistry of lobelia and suggests 
that until the results of further research provide the data on which
