alopecuroides, R.Br.; K. mitchelHaua, Nees; Fanicum decomposi- 

 tiim, R.Br. ; P. distachijiim, Linn. ; P. efitsum, R.Br. ; P. 

 gracile, R.Br.; P. leiLCophcum, H.B. et K.; P. initchellii, Benth.; 

 Pappophorum niyricans, R.Br. ; Sporoholns virginicvs, Kunth, 

 var. pallida; and Stipa sefacea, R.Br. All the specimens showed 

 remarkable growth, but the two most luxuriant forms were the 

 *' oat grass " {Anthistiria areuacea, F.v.M.), attaining a height of 

 6 feet 4 inches, and the " Kangaroo grass " {A. ciliata, Linn.), 4 

 feet 10 inches. This growth had been made in about four 

 months and, therefore, was green, rich and succulent. The 

 economic value of each species, its geographical distribution, and 

 special characteristics were pointed out. 



Dr. Greig Smith exhibited cultures of a slime-producing 

 organism, together with specimens of slime, in illustration of his 

 paper. He also showed a quantity of slime, 200 c.c, produced 

 by growing Pact, sacchari, Greig Smith, upon 10 plates of tannin- 

 glycerine-potato-agar, each containing 100 c.c. of medium. 



Mr. Froggatt showed a collection of the Psyllids described in 

 his paper. 



Mr. Baker exhibited a series of herbarium specimens and 

 timbers in illustration of his paper. Also an apparently roughly 

 dressed, sub-cylindrical stone, about 18 J inches long, and from 

 2-3 inches in diameter, recently found by Mr. W. Bauerlen in the 

 bed of Bushrangers' Creek, near AVellington, N.S.W. It is 

 believed to be another example of the curious Aboriginal Cere- 

 monial Stones, or whatever else they may have been, to which 

 attention has already been called by Mr. W. R. Harper in the 

 Society's Proceedings (1898, p. 420). 



Mr. J. J. Walker remarked that a similar stone had been given 

 to him at Tanna, New Hebrides, where it was said to be used as 

 a weapon of war to be hurled at the legs of an enemy. 



Dr. Hamlyn-Harris, a visitor, on the invitation of the President, 

 recounted some personal experiences of the phenomena attending 

 the fall of volcanic dust in the island of Barbadoes last year,
