them, after neutralization and separation of sulpliurous acid, to be evaporated 

 separately; this product also can be used as a feed by itself. The residual 

 liquid obtained from the acid and alkali treatment of cellulose may be treated 

 for the extraction of resins, tannin, sugar, etc., before being mixed with the 

 suljjhite liquor."

[Animal production], E. G. E. Sceiven and T. "Weedon {Ann. Rpt. Dept. Agr. 

 and Stock IQucensIand], 1918-14, pp. 36-39, 148-160, pis. S).— A statistical and

 on the desired points of conformation to be soug^it in judging horses, cattle, 

 sheep, and swine, together with information on the characteristics of the den-

The problem of early maturity in breeding from the biological standpoint, 

 E. MiJLLER {Dent. Landw. TierzucM, 18 {1914), No. 1, pp. 2-5; abs. in Internaf. 

 Inst. Agr. [Rome'], Mo. Bui. Agr. Intel, and Plant Bineascs, 5 {1914), No. 5, pp. 

 654-656). — From the observations of the author and other investigators it 

 appears that early maturity is not entirely dependent upon nutrition, which 

 is its principal determining factor, but is also influenced to a great extent 

 by the activity of the internal secretory glands. While there seems to be no 

 relation between increase in weight or volume of the digestive organs and 

 early maturing, there appears to be a connection between the physiological 

 activity of the digestive organs and early maturity. It appears that the early 

 maturity of the sexual organs and that of the body in general may be inde- 

 pendent of each other, for example the combination of high milk yield and 

 early maturity in the same animal seen in the Bates strain of Shorthorns. 

 The effect of early maturity on the length of life of the animal and the period . 

 of certain physiological functions has not been fully determined. 



Experimental studies in artificial fecundation, A. Pirocchi (Indus. Latt. e
