On the composition of the ash of the sap, leaves, and young stems of the 

 wild grapevine (Vitis cordifolia), O. M. Shedd and J. H. Kastlk {Jour. Amer. 

 Clicm. Nor., S-i (1012), No. 10, pp. U15-1J,2^).— After reviewing the re.sults ob- 

 tained by other investigators, the authors report analyses of a sample of sap 

 obtahiod April 14 from the cut ends of a wild grapevine, and for purpose of 

 comparison analyses of the leaves and young stems taken June 1(», as follows: 



('(iinpn.'<itioii of tilt: asJi of the sap, leaves, and young stems of the wUd grnpe- 



rine iV. cordifolia). 



The sap had a faintly acid taste, was slightly acid to litmus, and 2.S ce. of 

 decinormal sodium hydroxld solution was required to neutralize 100 cc. of the 

 sap against phenolphthalein. Its specific gravity was 1.0035. 



Composition of sweet apricot kernels, L. Rosenthaler and W. Schaeffeb 

 {Pharm. Zcntralhalie, 52 (Wll), Xo. 19, pp. 501, 508; ahs. in Chem. Zentbl., 

 1911, II, No. 1, p. 35; Analt/st, 36 {1911), No. 426, pt). ^50, /y.5i).— The compo- 

 sition of the kernels, obtained from the south of France, was as follows : 

 Water 4.33. total soluble matter 27.87, protein 31.4, oil 53.4, reducing sugars 

 S.OS. reducing sugars after hydrolysis 11.64, crude fiber 4.7t). and ash 2.G per 

 cent.
