PROCEEDINGS OF SOCIETIES. 
In any case I thank the Eev. L. Brakey for the courteous way in 
which he has pointed out the error committed. 
As regards the application of my apparatus to the determination 
of vision, the chief object of my note, I think its exactness cannot be 
disputed, and up to the present the arrangement has appeared to me 
to constitute a perfect optometer. 
Be pleased to receive, Sir, the assurance of my most distinguished 
consideration. 
Mouchet. 
PROCEEDINGS OF SOCIETIES* 
Brighton and Sussex Natural History Society. 
March 14th. — Ordinary Meeting. Mr. Hollis, President, in the 
chair. Messrs. B. Lomax, Mills, Pinker, and H. Yerrall were elected 
ordinary members. 
Mr. Wonfor announced the receipt for the Society’s library of 
£ Catalogue of Cretaceous Fossils,’ in the Brighton Museum ; ‘ The 
Willett Collection,’ from Mr. H. Willett; ‘Geological Notices of 
North Hampshire,’ by Dr. Stevens, from the author ; ‘ Proceedings of 
the Eastbourne Natural History Society,’ from the secretary ; and for 
the Society’s herbarium, from Mr. G. Davies, of a lichen new to 
Sussex, Bacidia muscorum, obtained by that gentleman a few days 
before at Patcham ; and a moss new to Sussex, Fissidens decipiens, 
from the moist part of the Downs above Slindon. Though common in 
mountainous limestone districts, it had hitherto escaped detection in 
Sussex, being confused with F. adiantoides, the large lax round cells of 
whose leaves differed from the pale-margined, densely-areolated leaves 
of F. decipiens. This moss had been found by Mr. Davies. 
Votes of thanks were given to the donors. 
Mr. F. E. Sawyer then read a very interesting paper “ On Bain, 
with special reference to the rainfall of Sussex, and how it is influenced 
by the South Downs.” 
A vote of thanks was given to Mr. Sawyer for his paper. 
Mr. Sewell exhibited a series of fossils from the Whincopp 
collection, kindly sent down for exhibition by Mr. Charlesworth. 
Among the most striking were teeth of different genera of sharks, 
scales of fish and reptiles, coprolites, ear-bones of porpoise, dental 
palates and tusk of walrus. 
* Secretaries of Societies will greatly oblige us by writing their report legibly 
— especially by printing the technical terms thus : H y d r a — and by “ underlining” 
words, such as specific names, which must be printed in italics. They will thus 
secure accuracy and enhance the value of their proceedings. — E d. ‘ M. M. J.’
