1. " On the Rhastic and some Liassic Ostracoda of Britain." By 

 Prof. T. Eupert Jones, F.R.S., F.G.S. 



In this paper the published observations on the occurrence of 

 these Microzoa in the Rhastic and Lower Liassic strata of England, 

 chiefly in Gloucestershire and Somerset, by the Rev. P. B. Brodie, 

 H. E. Strickland, C. Moore, and others, are first of all recorded ; 

 and the various notices of the so-called Cypris Uassica in various 

 palseontological works are considered. Numerous specimens sub- 

 mitted by the Rev. P. B. Brodie, the Rev. H. H. Winwood, and 

 Mr. E. Wilson, and some few examined in the Geological Society's 

 collection, have been studied, with the result of determining, it is 

 hoped satisfactorily, the characters and alliances of Darioinula Uassica 

 (Brodie) and of six or seven other species found in the same and 

 the associated series of strata. The Darioinula globosa (Duff), from 

 Linksfield, Morayshire, is also critically re-examined as one of this 

 interesting series of Rhastic Ostracoda. The other species belong 

 for the most part to Cytheridea ; thus most of them probably lived 

 in brackish or estuarine waters. 



2. " Leigh Creek Jurassic Coal-Measures of South Australia : 

 their Origin, Composition, Physical and Cbemical Characters ; and 

 Recent Subaerial Metamorphism of Local Superficial Drift." By 

 James Parkinson, Esq., F.G.S., F.C.S. 



This paper contains an account of the lignitic coal of Leigh 

 Creek and associated rocks. Analyses are given, as illustrating 

 comparisons between the Leigh Creek coal and Jurassic and other 

 coal-bearing rocks found elsewhere. The author discusses the origin 

 of the Leigh Creek deposits, and describes certain peculiarities 

 noticeable in the superficial materials, which he discusses in another 

 paper. 



3. " Physical and Chemical Geology of the Interior of Australia : 

 Recent Subaerial Metamorphism of Eolian Sand at ordinary atmo- 

 spheric temperature into Quartz, Quartzite, and other stones." By 

 James Parkinson, Esq., F.G.S., F.C.S. 



South of the Flinders Range fragments of stone of all sizes are 

 found on the ground, the origin of which the author discusses. He 

 maintains that they were formed by subaerial metamorphism of 

 Eolian deposits.

ACTION OF GLACIERS. 



Sir, — I wish to call the attention of geologists more experienced 

 than myself to the Eidfjordsvand, in Norway, from which I think 

 important lessons may be learnt. 



The Eidfjordsvand is a lake about 4 miles long and 245 feet deep, 

 and is remarkable for its desolate grandeur. The river that forms 

 the Voringfos flows through it into a branch of the Hardangerfjord,
