144 NOTES AND EXHIBITS, 



septicaemia (mice, rabbits), occasionally found in human sputa 

 and coating of the tongue. It kills common mice in about two 

 days. (5). Micrococcus tetragenus (GrafFky), the misrococcus of 

 septicaemia in white mice, occurring in human sputa, especially in 

 cases of pulmonary tuberculosis. White mice inoculated with it 

 die within 3-6 days. (6) Sarcina lutea and (7) Bacillus pyocyaneus^ 

 both non-pathogenic. The former is present in the air, whence 

 it sometimes appears, as contamination, on gelatine-plates for 

 cultivating bacteria. The latter, a very delicate bacterium, 

 produces the green-blue colour, which sometimes makes its 

 appearance on the material used for dressing purulent wounds. 

 This pigment, called pyocyanin, is also produced by the micro- 

 organism in its artificial cultivations. All the above exhibits 

 were accompanied by diagrams, showing the microscopical 

 appearances of the bacteria, as examined qiute pure, or occurring 

 in the blood etc. 



Dr. Foucart exhibited a large specimen of what in Australia is 

 usually known as Meerschaum, from the Nambuccra River. It is 

 a freshwater deposit of silicate of alumina, containing impressions 

 of leaves. These appear to belong to the Cupuliferaj, and are 

 therefore in all probability of the Eocene or Miocene peiiod. 



Mr. F, B. Kyngdon exhibited portions of shale from Mt. 

 Piddington, near Mount Victoria, with impressions of Thinnfeldia 

 odontopteroides, &c. Also, a concretionary bezoar from the stomach 

 of a spermwhale. 



Dr. Cox exhibited a basketful of the fruit of the Rose Apple 

 Uugenia Jainhosa, which is now in full bearing in several Sydney 

 gardens. It has a very pronounced aroma and flavour of Conserve 

 of Roses, and is used in the East Indies for sherbets and con- 

 fectionery. Also a fine collection of Lepidoptera, made by the 

 late Mr. Kunstler at Perak. 



Ml'. Percival Waddy, of Maitland, communicated an account of 

 the flowering of a, plant of Oenothera Lamarckiana, which produced 

 278 blossoms, each averaging from 3A to 3f inches in diameter.
