 A-anadiinn, a description of the principal vanadium bearing substances in Argen- 

 tina, and a discussion of methods, gives an account of studies on vanadium as 

 Influencing vegetable growth, with the conclusion that this element may be ab- 

 soi'bed and stored by plants, which may show anomalies of growth therefrom. 



Arsenic and manganese in some vegetable products serving as animal 

 food, F. Jadin and A. Astruc (Compl. Rend. Acad-. 8ci. [Pans], 1S9 (WlJf), 

 No. 3, pp. 268-270) .—In continuation of previous work (E. S. R., 29. p. G28), 

 results are given in tabular form of analyses made of 12 plants (also of certain 

 mixtures thereof) commonly fed to animals usetl for human food, indicating the 

 percentages of arsenic and also those of manganese found in the fresh or the 

 dry form of each. 



On the correlation between somatic characters and fertility, J. A. Harris 

 (Amer. Jour. Bot., 1 (191Jf), No. 8, pp. 898-1,11, figs. 4).— The author presents 

 data bearing upon the relationship of somatic develoiiment (as measured by the 

 fruits borne by the individual plant) to fruit fertility (as measured b^ the 

 number of ovules forming ;ind of seeds developing). 



Data obtained and analyzed are considered to indicate that the correlation 

 between number of pods per plant and number of ovules per pod is positive but 

 low, and that the correlation between pods per iilnnt and seeds per i)od is for the 

 most part positive and lower. 



It is held that " there is some correlation between the number of pods per 

 plant and the number of ovules which develop into seeds, which is in part at 

 least independent of (although it may be inseparably bound up with) the mor- 

 phogenetic factors which link together the magnitudes of the two characters," 

 ])ods per plant and ovules per pod. This corrrelation is designated as more 

 truly physiological than morphogenetic, although there is thought to be no very 

 sharp line of demarcation between the ]iliysiological and morphogenetic in 

 problems of the kind here considered. 



Hybrids of (Enothera biennis and CE. franciscana in the first and second 

 generations, P.. M. Davis (A ?>.<?. in Science, n. scr., 41 {1915), No. 101,8, p. 177).— 

 The author reports upon a study of 1.S0G plants grown from reciprocal hybrids 

 of the above species of CT^nothera. The second generation of this cross is said 

 to jiresent a wide range of forms, and among them were a number of plants 

 with combinations of characters that appear to have fulfilled in essentials the 

 requirements of .synthetic (U. laniarckiana-Vike hybrid.

 This inventoiy gives a descriptive list of about 4(X) numbers of seeds and plants 

 imported from various parts of the world for testing in the Fnited States.

Grass pastures for irrigated lands. J. S. Wki.cii (Idalw Sta. Bui. 80 {191},), 

 pp. 15, figs. S). — ^This bulletin describes methods of seeding, irrigating, and 

 care of irrigated grass pastures in which Kentucky blue grass, smooth brome 

 grass, orchard grass, timothy, meadow fescue, redtop, tall meadow oat grass, 

 English rye grass, Italian rye grass, Canada blue grass, wbite clover, alsike 

 clover, and rwl clover were used singly and in mixtures. The value of these
