cliffs about the Bombala river, are about 100 to 120 feet high, and 
formed of very dark limestone, crowded with fossils, chiefly Penta- 
merus. In the author's opinion there has been great disturbance in 
this region, resulting in a complete change in the course of the 
river Bombala and a displacement of the shale. A mass of ferru- 
ginous sandstone has also been upheaved. This, as well as the 
other rocks in the neighbourhood, contain Upper Silurian fossils. 
It appears to have been altered by heat. Pockets of galena and 
copper are occasionally found in the district, and there is a vein of 
haematite. Clay-slates occur as well as the above rocks, the cleavage 
being generally vertical or nearly so.

ON KADIOMETEKS. 
To the Editors of the Philosophical Magazine and Journal. 
Gentlemen, 
1" HAVE learned in a roundabout way that Prof. Osborne Bev- 
-*- nolds is annoyed with me because I have not carried out an 
intention I expressed in a letter to him two years ago, which was, 
as well as I can recollect, to publish something more on the subject 
of Badiometers, and to state that I was on the whole satisfied 
with his position. 
I did not do so because I got rambling on other matters, and 
thought that by my silence I practically accepted his answers to 
my questions as published in the Philosophical Magazine. And as 
concerns some points I wrote to him about privately, and which 
he very kindly answered at great length, I hardly thought them 
worth publishing alone (though I asked leave to incorporate them 
in what I then intended writing upon the subject, and was kindly 
authorized to do so) ; for I felt sure that as it was my stupidity that 
had mistaken his meaning, others were very unlikely to make such 
mistakes and so would not take any interest in them. 
I regret taking up the pages of the Philosophical Magazine with 
such a purely personal matter; but as I should be very sorry 
indeed that any one, and least of all one who has treated me as 
Prof. Beynolds has done, should suppose that I shirked expressing 
myself as satisfied with answers to questions I raised, I hope you 
will publish this letter ; and I further hope that Prof. Reynolds 
will forgive me for having forgotten my promise, which I would 
certainly never have done if I had thought that he cared one bit 
what I said of his work, which speaks for itself too well for any 
mere opinion of one such as I am to benefit or injure. 
Yours obediently, 
Clarisford, Killaloe, GEOBGE Feancis FlTZGEBALD.
