276. Pfeffer (l.c. [275], p. 86) states that all the parenchymatous cells in the 

 staminal filaments of Centaurea Jacea have thin walls (apart from the outer epi- 

 dermal walls) ; the author's observations do not agree with this statement.

279. G. Haberlandt : Biol. Centr. 15, 1905. In this paper the author has demon- 

 strated that terms such as "sense-organ," "sensitiveness," "sensation," per- 

 ception," etc., may be legitimately used in the comparative physiology of animals 

 and plants, even when one is only concerned with the physical aspect of stimulation 

 and response ; the possibility that psychical processes are also involved, can neither 

 be proved nor disproved in the case of lower animals and plants, and is in any case 

 of secondary interest to the physiologist, Cf. also G. Haberlandt : Almanaeh d.
