A MEMOIR OF ROBERT ETHERIDGE, F.R.S. 181 
portions of the work have unfortunately remained in 
manuscript, and it is needless to say that every year 
increases the difficulty of keeping pace with the additions 
and with the manifold and perplexing changes in nomen- 
clature of the species. 
Etheridge, wffio was elected President of the Geological 
Society in 1881 and 1882, availed himself of the materials 
he had so industriously gathered together to give in his 
two addresses an Analysis and Distribution of the British 
Palaeozoic and Jurassic Fossils. Later on, in 1885, he 
prepared an elaborate volume on Stratigraphical Geology 
and Palceontology, which was published as Part II. of a 
second edition of Phillips’ MoMual of Geology. This was 
practically a new work, and it consisted of rather full 
particulars of the British strata and their fossils, with 
ample references. Of his other works a list has been 
already published.^ 
Considering his extensive knowledge and experience as 
a palaeontologist, Etheridge described comparatively few 
new species, but these include various forms of inverte- 
brata and some plants, from all quarters of the globe. 
Attention may, however, be called to the work which has 
more local bearings. 
That Etheridge had acquired an intimate knowledge of the 
geology of the Bristol district is apparent from the three 
lectures he gave to the Bristol Mining School ^ in 1857 
on ‘‘ Geology : its Relation and Bearing upon Mining,” 
printed, with other lectures, in a little volume entitled 
Lectures Delivered at the Bristol Mining School, 1857 (8vo, 
Bristol, 1859).

2 The Bristol Mining School was established in 1856, and “was 
designed to enable those who wish to fill situations of trust in 
connection with mining to obtain a good, cheap, and practical 
education.”
