flower is not fertilized by its own pollen ; the stigmatic lobes remaining 
closed until the pollen deposited on the style has been cariied away by 
insects, but then opening to receive the pollen of other flowers. 
(2) “The Geology and Physical Geography of the State of Perak,” 
by the Rev. J. E. Tenison-Woods, F.G.S., &c. The principal formation 
is granite, surrounded and overlaid by schistose and slaty rocks of high 
geological antiquity. Above these are found slates and limestones, 
generally in isolated outliers, giving evidence of great and long 
continued erosion. This is also testified by the extensive tracts of drift 
and alluvium, derived from the older rocks, and containing large 
deposits of stream tin, which have been worked from a very remote 
period. No lodes have, up to the present time, been explored by the 
miner, who has contined himself entirely to alluvial workings, and the 
portions of the country thus utilized are, in the author’s opinion, of very 
small extent in comparison with the whole area of tin-bearing land. 
(3) “Note on an apparently new parasite affecting sheep,” by R. 
von Lendenfeld. In several localities sheep were affected by a disease, 
similar in appearance to epithelial cancer, which appeared on the feet 
behind the hoofs and on the lips. The histological investigation shows, 
that the rete malphigii is inflamed and the papille attain a very large 
and abnormal size ; the outer layer of the skin, and the horny epithelium 
are very much thickened, and it is apparent that between the horny 
layers, granular masses—apparently parasites—are disposed in which 
nuclei can be detected. The author supposes these to be an ameeba, 
and to cause by irritation the hypertrophy of the epithelium. The 
sections were exhibited under the microscope, the specimens were 
hardened with chromic acid and stained with picric-acid-carmin. 
(4) On the temperature of the body of Ornithorhynchus paradoxus,” 
by N. de Miklouho-Maclay. The result of some observations on the 
temperature of the Ornithorhynchus is here given, showing it not to 
exceed 40° C. or 76° Fahr. Previous observations made by the Baron 
had shown that the temperature ot the body of the Echidna was at least 
5° Fahr. higher than that of the other Monotreme. 
Mr. W. H. Caldwell, B.A., exhibited several specimens which he 
had recently obtained in Queensland, showing the stages in the develop- 
ment of the Monotremes from the laying of the egg to the hatching.
