names gliadine and glutenine are given. The baking value is 
shown to depend upon the ratio in which these two are present 
in the flour.—On the origin of the beetroot disease, by M. Paul 
Vuillemin. It is shown that the parasite named ZAxty/oma 
leproideum by M. Trabat, and Qdomyces leproides by M. 
Saccardo, is not a new species, but is identical with the 
Cladochytrium pulposum of Fischer.—New observations on 
scab in potatoes, by M. K. Roze.—On the mode of formation 
of zeolites, by M. A. Lacroix. In the Pyrenees, zeolites are 
found in considerable quantity which have been formed by the 
action of nearly pure water, at temperatures near oO Cx upon 
nasic felspathic rocks.—The application of Réntgen rays to 
Paleontology, by M. Lemoine.—On the apparent density of

Linnean Society, September 30.—The President, Mr. 
Henry Deane, in the chair.—The Sooty-Mould (Capnodium 
cttricolum, n.sp.) of Citrus trees: a study in polymorphism, by 
D. McAlpine. The species so far as known is peculiar to 
Australia. It has a remarkable life-history, and well illustrates 
the phenomenon of polymorphism.—Australian Lampreys, by 
J. Douglas Ogilby.—On the botany of the Rylestone and 
Goulburn River Districts, N.S.W., by R. T. Baker.—Note on 
Cyprea angustata, Gray, var. subcarnea, Ancey, by C. E. 
Beddome.—Mr. Edgar R. Waite contributed a note on the 
range of the Platypus. The northern habitat is extended to 16° 
45'S. and localities quoted on the Gulf of Carpentaria 140° 
56’ E., the most north-westerly point hitherto recorded.—Mr. 
T. Whitelegge exhibited a rare and curious Isopod, A mphorotdea 
australiensis, originally described from N.S. Wales by Dana in 
1852, since when it appears to have escaped notice. The specimen | 
exhibited was obtained on seaweed at Maroubra Bay last June ; 
when alive it was bright olive-green, and of a similar'tint to the | 
seaweed to which it was adhering.—Prof. David contributed the 
following note on a remarkable radiolarian rock from Tamworth, 
N.S.W. :—‘‘ On September 10, in company with Mr. D. S. 
Porter, I observed the occurrence of a remarkable radiolarian 
rock on the Tamworth Temporary Common. Of this rock a 
hand specimen and section prepared for the microscope are now 
exhibited. The section is an opaque one prepared by cementing 
a slice of the rock about one-tenth of an inch thick on to an 
ordinary glass slip with Canada balsam and then etching its 
upper surface with dilute hydrochloric acid. The rock being 
partially calcareous, probably an old radiolarian ooze, the lime 
filling in the delicately latticed shells and interstices between the 
spines of the radiolaria is dissolved out, and the siliceous shells 
of the radiolaria become exposed to view. Some of them are 
exquisitely preserved for palcozoic radiolaria. The rock of 
which they constitute by far the larger proportion weathers into 
a brown pulverulent friable material like bath brick. The 
unweathered portions are dark bluish-grey and compact. The 
radiolaria appear to. be chiefly referable to the porulose division 
of the Legion Spumel/arza. This discovery confirms the previous 
determinations by me of radiolarian casts in the rocks of the New 
England district, and of the Jenolan Caves, N.S. Wales. The 
geological age of the formation in which this rock occurs is 
probably either Devonian or Lower Carboniferous, as Zefzdo- 
dendron australe appears to occur on a horizon not far removed 
from that of this radiolarian rock. The Moor Creek limestone, 
near Tamworth, I find also contains numerous radiolaria.””
