NATURE 



[June 29, 1916 



The area comprises thret; chief plant formations, 

 namely, woodland, park-like grassland with scattered 

 trees arid bushes, and in the more low-ljdng parts of 

 the • latter, sedge vegetation. The soil is essentially 

 uniform throughout the area, being a fine red-brown 

 loam containing comparatively few large particles or 

 stones. No marked differences in climatic or edaphic 

 factors distinguish the woodland from the grass land, 

 though these are of strikingJ4y different appearance 

 and are separated by a sharp boundary line. — 

 J. S. V. d. Lingen: (i) Note on the radiations 

 emitted by degenerating tissues ; (2) note on the 

 ionisation produced by degenerating nerve-muscle pre- 

 parations. The author brings forward some evidence 

 that organic tissues may post mortem give rise to 

 ionisation, which can be detected by the discharge of 

 an electroscope. On the second and third days after 

 death the discharge seems to attain its maximum. 

 There is also some evidence that radiations are given 

 off which can affect photographic plates. The author 

 states that control experiments are in progress.
