Nepenthes— Animals. II. Biologfical Notes. By H. Jensen 

 (Ann. Jard. Bot. Butt. 3rd supp. 2nd pt. 1910, pp. 941-946).— In this 

 paper it is shown that the animals which are adapted to carry on their 

 Hves in the digestive juice of Nepenthes pitchers secrete an anti-ferment 

 which counteracts the digestive ferment of the plant, and enables them 

 to live in its juice without suffering harm. Nine animals altogether 

 were found living in these pitchers at Buitenzorg — three fly larvae, 

 four gnat larvae, one small round worm, and one mite. — E. B. 



Nepeta Mussinii. By E. M. Whitehead {Garden, Aug. 29, 1910, 

 p. 418). — This Catmint flowers for five months of the year and 

 neither wet nor drought affect it. It has lavender labiate flowers, and is 

 useful as a framework to Antirrhinums or as a neutral undergrowth to 

 beds of China Eoses. Any side-shoot will strike readily, or, better still, 

 an old plant may be divided in spring. The divisions will form bushy 

 plants by July. — H. R. D. 



Nephrolepis magrnifica {Gartenflora, vol. hx. pt. xii. pp. 262- 

 263; 1 fig.). — This lovely fern is suitable for growing in rooms.

New Guinea {Die Gart., July 30, 1910, p. 391).— The following 

 plants are noted as cultivated in German New Guinea: Ficus, Hevea, 

 Kickxia hrasiliensis , and Cocoa, as well as Cocos. Peterhafen is a 

 small island. The population is only about 200, but they are 

 so lazy that coolies have to be brought from New Pomerania. The 

 temperature varies between 37^° to 44° C. Both the fauna and flora 

 are comparatively poor. A Casuarina is the principal forest ft.ree. 

 Artocarpus integrifolia is plentiful, but many trees are cultivated, as is 

 the Pineapple. — G. R. 



Nitrification, Seasonal, as Influenced by Crops and Tillag-e. 



By C. A. Jensen {U.S.A. Dep. Agr., Bur. PL hid., Bull. 173, April 

 1910; 7 diagrams). — Shows the seasonal changes in the water-soluble 

 nitrates in summer-fallowed land, wheat land, and corn land, and the 

 rates and extent of the seasonal removal of the nitrates by these crops.
