 Five grams of cacao or chocolate is extracted with ether, and the residue repeatedly 

 treated by washing and decanting with successive portions of water. The heavier 

 particles remaining in the beaker are transferred to a watch glass, dried and weighed. 

 This residue may then be examined microscopically and the percentage of hulls 

 estimated.

BOTANY. 



The resumption of root growth in the spring, E. S. Gofi<' ( Wisconsin Sta. Rpt. 

 19(j0, pj). ;^91-;:94, figs. 3). — In a jtrevious iep(jrt (E. S. R., 11, p. 511) the re.'^ults of 

 investigaticjns made in the sjiring of 189S upon the roots of perennial plants were 

 shown. The winter had been, for that region, an unusually mild one and as a result 

 the roots of all plants examined were found to have started growth at the points 

 where growth had ceased in autumn. The succeeding winter was an extremely severe 

 one, and examination shf)wed tiiat the roots of only the hardiest plants started growth 

 from their tips. The roots of all fruit trees at the station were more or less damaged,
