GEOLOGICAL ‘NOTES AND QUERIES.’ 
To the Editor. 
My pear Srr,—In the early part of the past year, I ventured to 
suggest to the Council of that very useful body, the ‘Geologists’ Asso- 
ciation,’ that an extension of the aid they were giving to geological 
observers would result from the periodical publication, monthly or 
quarterly, of a ‘Notes and Queries.’ To illustrate my meaning prac- 
tically, I took the further liberty of contributing the first number, 
having sundry enquiries myself to make, needing, like others, co-ope- 
rative help. This little olla podrida of mine the Association pub- 
lished, with an official foot-note of approval and explanation. But 
though still convinced of the value of such means of distributing 
and acquiring help within the limits of the ‘Association,’ I am so 
greatly of opinion that more extended and equally valuable aid 
may result from embodying the scheme with that of the GroLoGicaL 
MaGazineE, that I beg for some small space wherein to remark upon 
it. Although a desultory system of notes and enquiries did obtain 
during the existence of the respected predecessor of the GEOLOGICAL 
Macazine, the scheme upon which it was cast differed somewhat 
from the arrangement I would suggest. 
My remarks upon the plan need be but short. The arrangement 
in that valuable friend of Literary men, ‘ Notes and Queries,’ is the 
one which [I should like to see applied to the help of Geological 
students: everyone being familiar with this model, I need not describe 
it. My remarks will be rather directed towards indicating subjects 
which may both lead to the help of individuals, and at the same time 
advance the progress of the science. 
The very suggestive article by Professor Rupert Jones which 
inaugurated the New Year, and to which, unknowingly, I added a 
kind of postscriptal paper, will save me mentioning our wants as 
regards the paleontological, physical, and petrological studies which 
belong to the older half of the Paleozoic epoch; and save my bring- 
ing forward, as a witness of the usefulness of my plan, any more 
puzzled student of rocks older than the ‘ Mid-Silurian’ student. At 
this stage in the chronicle of past time begin my inquiries. 
1. Will some one kindly ask what are now the boundaries of the 
‘ Middle Silurian,’ and what are its frontier relationships with rocks 
above and rocks below? 2. Also whether the May Hill Sandstone, or 
any ‘ Llandovery’ rock, is being worked now anywhere in Britain ? 
While making these queries, I call the attention of the Malvern 
geologists, and other observers situated thereabouts, to the extra- 
ordinary abundance of Tentaculites in the Upper Llandovery Sand-
