BOTANY. 23
A new method of quantitatively or qualitatively examining albuminoids,
diastases, alkaloids, leucomains, or toxins, particularly those in urine, P. CHIBRET
(Compt. Rend. Acad. Sci. Paris, 128 (S199), No. 7, pp. 431-433).
A method for distinguishing between cotton-seed, sesame, peanut, and olive
oils, M. TOIrTELLI and R. RUGGERI (Staz. Sper. Agr. Ital., 31 (1898), No. 3, pp. 249-269).
Notes on the arachidic and lignoceric acids of earthnut oil, and their estimation,
L. ARCHBUTT (Jour. Soc. Chem. Ind., 17 (1898), No. 12,pp. 1124-1127).-The results
obtained are applied in the detection of peanut oil in olive oil.
Colorimetric determination of iron in water, A. SEYDA-STETTIN (Chem. Ztg., 22
(1898), No. 104, p. 1086).
A needed modification of the determination of calcium carbonate in marls
and soils, A. MAYEIR (Landwi. Vers. Stat., 51 (1899), No. 4-5, 1pp. 339, 340).-The substitution
of acetic acid (1 part of glacial acetic acid to 2 parts of water) for the
hydrochloric acid usually employed is recommended. Acetic acid gives very accurate
results with pure calcium carbonate in the Scheibler apparatus and possesses
the advantage over hydrochloric acid of attacking but slightly iron carbonate,
which is sometimes found in considerable amounts in marls and soils and which is
of no value as an amendment.
Some notes on the content of volatile acids in wine, G. MORPURGO (Oesterrr.
Chem. Ztg., 2 (1899) No. 8, pp. 209-211).
On the formation of sugar from the albumen of eggs, F. BLUMENTHAL (Compt.
Rend. Acad. Sci. Paris, 128 (1899), No. 2, pp. 117-120).-Recenlt work on this subject
is briefly reviewed, and experiments by the author reported. The author believes
that 8 to 12 gum. of sugar may be formed from 100 gin. of albumen (from white of egg).
A simple apparatus for the determination of nitrogen by the Kjeldahl
method (Ztsclir. lAallyt. ClemL., 38 (1899), No. 3, p. 166; abs. in Chenm. Centbl., 1899, I, p.
948, fig. 1).
Apparatus for rapid analysis of milk, G. D. MACDOUGALD (Jour. Soc. Chem.
ltd., 18 (1899), .No. 3, pp. 235-238, fils. 15).
A new attachment for the Soxhlet extractor, S. ROBERTrSON (Arch. EHyg., 30
(1897) ,p. 318; abs. in Ztschr. Analyst. Chem., 38 (1S99), No. 1, . 45, fig. 1).-The substance
is contained in a glass cylinder with perforated bottom, over which a filter laper
can be tied. Caps fitting over the top and bottom of the cylinder are provided for
use during drying and weighing.
Report of agricultural-chemical examinations for 1898, V. STEIN (Tidsskr.
Landdkon., 17 (1898), Io. 7-8, pp. 500-523).--esults of analytical work done for the
Royal Danish Agricultural Society in examinations of feeding stuffs, dairy products,
fertilizers, etc.-F. w. WOLL.
BOTANY.
Varieties of corn, E. L. STURTEVANTI (U. S. Dept. Agr., Office of Experiment
Stations Bul. 57, pp. 108, figs. 14).-In this monograph about
800 varieties or synonyms are treated, and an attempt is made to place
the nomenclature upon a sound scientific basis. The system of classification
adopted brings closely related forms together and in this way
a very consi(lerable duplication of varieties is shown. The main divisions
which the author follows are those described by him in the Bulletin
of the Torrey Botanical Club for August, 1894 (E. S. R., 6, p. 274).
Poa fendleriana and its allies, T. A. WILLIAMS (U. S. Dept. Agr.,
Division of Agrostology Circ. 10, pp. 6, fig. 1).-The author has attempted
to remove the cause of munhe confusion in herbaria by presenting a
study of this species of grass and the numerous forms which have been
