silky needles, m. 123\ [A) and warm HN0 3 gave (C0 2 H) 2 , even when HOAc 

 was used as diluent. Coned. KMN0 4 also gave (C0 2 H) 2 . Fusion with 5 parts 

 KOH at about 250 : gave a volatile oil with the odor of AniOH. The aq. 

 soln. of the fusion was acidified and extd. with E-t 2 0. yielding BzOH, 

 isolated as the Ca salt. In another expt. the aq. soln. of the fusion 

 was satd. with C0 2 , shaken out with Et 2 and then with ale., which did not 

 mix with the soln. The ale. soln. containing K salts was evapd., acidified with 

 H 2 SO^, and distd. with steam. The resulting volatile acids were purified 

 through the Ba and Xa salts, and finally sepd. as the Ag salts. HOAc and 

 C\ H :j -C0 2 H were found. Boiled with HI for 12 hrs., (A) yields a substance, C 22 

 H 22 6 , faintly yellow, silky needles, m. 180-1°, changes into short rhombs 

 with identical properties on standing overnight in the mother-liquors when 

 erystd. from ale. gives a deep green color in ale. with FeCl 3 ; its methyl 

 derivative, prepd. with Me 2 S0 4 and aq. KOH containing a little ale. to 

 facilitate solu. m. 216° ; the monoacetyl derivative, using Ac 2 O and NaOAc, 

 m. 218-9°.— Chemical Abstracts, Aug. 10, 1915 ; p. 2061.

A slender tree with drooping branches, branchlets black. 

 Bark light brown, rather shining, very thin, smooth. Wood 

 greyish white, hard : many dark concentric lines, resembling 

 annual rings, without or with very few pores ; very numerous, 

 narrow, anastomozing white brands, in which the scanty 

 moderate- sized pores appear. Medullary rays moderately 

 broad, white, regular 1 ' Gamble). Leaves red. when young 

 2-4 in., thickly membra - anceolate, occasionally oblanceolate, 

 nearly sessile, mucronate, rarely obtuse. Secondary nerves 

 slender. 6-10 pair, a few shorter, very slender : intermediate nerves 

 between. Flowers tetramerous, small. Sepal- orbicular, outer 

 small petals rather smaller. Male flowers: a central, round or 

 4-sided mass with crowded, numerous. 2-celled anthers: in ter- 

 minal 3-7-flowered, often pedunculate cymes ; pedicels Jin. long. 

 Anthers numerous, 2-celled od short filaments crowded on a
