Sir Roderick also added the following observations: — 
"There is an observation of yours — nay an important discovery — to 
which I must call the attention of my associates in this age of forward 
movement. In the Geological Journal, Vol. 3, p. 361 you notice the 
existence of a human skeleton in the body of a shelly raised beach. This 
fact is of vast importance now that the intermixture of flint knives and 
the implements of men have been detected in diluvial accumulations with 
Mammoth &c. 
Yours very truly, 
Nov. 5, 1859. Rodk. Murchison." 
After receiving the letter just quoted from Sir Roderick Murchison, I 
allowed the question relative to the Irish Llandeilo beds to remain at rest 
for some time, but hearing it repeated that Llandeilo rocks were not known 
in the South-East of Ireland, I sent a number of the fossils which I had 
discovered at Duncannon, to Jermyn Street, the head quarters of the 
Geological Survey. Shortly afterwards the late Mr. Salter, then Govern- 
ment Palaeontologist, returned the specimens, all of which he had named 
in the following list which was headed — 
Llandeilo Flags, Duncannon, County of Wexford. 
Calymene duplicata... ... ... 2 specimens. 
Lingula ovata. ... ... ... 3 do. 
Lingula, not named. ... ... 3 do. 
Orthis striatula ... ... ... 1 do. 
actonia? ... ... ... 2 do. 
biforata ... ... ... 1 do. 
Leptama sericea ... ... ... 2 do. 
Chgetetes petropolitanus ... ... 2 do. 
Stenopora fibrosa ... ... ... 1 do. 
Thus far there can be no doubt that all these specimens from Duncannon 
are unquestionably Llandeilo Flag fossils. Along with these I sent a set of 
specimens from Newtown Head, near "Woodstown, County of "NVaterford, 
and which I had considered as belonging to the Caradoc strata, but Mr. 
Salter appears to have thought that they might also be included in the 
Llandeilo scries, and he marked the list with, a note of interrogation and 
appended names to the fossils as follows: — 
Llandeilo Flags (r), Newtown Head, County of Waterford. 
Crania divaricata 1 specimen ) 
Lingula ovata ... ... 1 do. 1
