tinued for a considerable time, kill the spores. The toxic action is 

 exerted in a very short time when the alcohol acts alone, or more slowly 

 in the presence of vapor of pare water. Increasing the strength of the 

 solution or raising the temperature rapidly increases the toxic action.

The province and problems of plant physiology, D. T. MacDougax (Science, n. 

 ser., 7 (1897), No. 168, pp. 369-374).

 Weaver (Proc. Iowa Acad. Sci., 4 (1897), pp. 132-137, ph. 4).— Studies were made of 

 the leaves of Andropogon provincialis, A. nutans, A. scoparius, A. .sort/hum, and A.

 The author thinks the existence of multipolar spindles not necessarily an argument 

 against the existence of dynamic centers during cell division. Centrosomes may 

 not always be definite morphological units. It is affirmed that the higher plants 

 possess differentiated elements whose role is the same as that of those analogous 

 bodies observed in the lower plants and in animals.
