O. F. Cook: ‘Do termites cultivate fungi ?—In the 
nests of Liberian species of Termes are found honeycombed 
masses of a punk-like substance, irregularly rounded in gen- 
eral shape. Over all the surfaces and passages of this mate- 
rial there grows the mycelium of a mucor-like fungus, having 
white sporangia about 5 mm. in diameter. The young 
termites apparently feed upon these fungi. A similar condi- 
tion of things obtains with another species of Termes living 
underground.

WILLIAM P. WILSON: “Adaptations of plants to environ- 
ment.”—A comparison of lowland vegetation near the sea 
with that of desert and mountain areas. A large number of 
lantern slides were shown, illustrating the ways in which plants 
of these regions protect themselves against excessive evapo 
ation, particularly by change in position of foliage. In such 
leaves the author found no change in the position of t 
chlorophyll bodies. The stomata in the exposed leaves were 
closed, while those in shaded leaves were open. ‘
