 lyptus macarlhuri. (Journ. Roy. Soc. New South Wales. L. 2. 

 p. 177-180. 1916.) 



This species is one of the few of the genus from which oil can 

 be distilled from the bark. Up to the present the oil has only been 

 obtained from the leaf of Eucalyptus macarthuri. In some cases 

 it has been found that the yield is even greater than from the 

 leaves. 



Analysis has shown that the two oils are identical and need 

 not be separated for commercial purposes. M. N. Owen (Kew).

In ersterer Art wurde nachgewiesen: Fett, Harz, Mannit, 

 Mykose, d-Glukose, ein in reicher Menge vorkommender Körper 

 phlobaphen- oder resinotannolartiger Natur und ein amorphes 

 Kohlehydrat. Der Abbau der Membransubstanz liefert reichlich 

 d-Glukose, daneben Mannose, Glukosamin und Pentosen. — In der 

 2. Art fanden sich Fett, Harz, ein Ergosterin, ein phlobaphenartiger 

 Körper, Mannit, Mykose, zwei amorphe Kohlehydrate. In der 3. 

 Art fand Verf.: Harz, Fett, einen ergosterinartigen Körper, My- 

 kose, viel eines schleimigen Kohlehydrates, das beim hydrolytischen 

 Abbau namentlich Mannit und etwas d-Glukose liefert. Aus der 

 Membransubstanz wurde beim Abbau mit HCl Glukosaminochlor- 

 hydrat erhalten. Matouschek (Wien). 



Troup, R. S„ Pinus longifolia, Roxb. A Sylvicultural Study. 

 (The Indian Forest Memoirs. Sylvicultural Series. 1. 1. p. 1 — 126. 

 1916.) 



Pinus longifolia, Roxb., the Himalayan long-needled pine is one 

 of the most important trees known to Indian Forestry. Forming 

 gregarious forests at comparatively low elevations, its timber can 

 be worked out at a lower cost than is the case with species gro- 

 wing in more sporadic form and less accessible tracts. It has also 

 established its reputation as a producer of resin. 



In this article the distribution, locality and types of forest, syl- 

 vicultural characters and requirements, regeneration, external dan- 

 gers, tending Operations, and Systems of management are described, 

 and much Statistical information is given, chiefly in tabular form. 



The work is illustrated by a large number of photographs, 4 

 coloured plates, and by 5 curves, showing growth in height, growth 

 in girth, volume production, and mean annual increment.
