Africa and the Sudan. The culture represented is thus called the Azilio- 
Tardenoisean ; it is post-glacial and marks the transition stage of the 
Palaeolithic and Neolithic ages. The flints were found mainly on the 
moors of Rish worth and Soy land, and he and Dr. J. Grainger had picked 
up a few about a mile beyond the Derby Inn. Mr. Priestley also referred 
to the archaeological features of Ryburndale, and gave examples of 
interesting place-names among which the derivation of the present 
Joiner Stones ’ from the Saxon ‘ Ionna Staner ’ — an inner place of 
holy stones — may be mentioned. 
A hearty vote of thanks was accorded to the Local Secretary (Dr. J. 
Grainger) and to the several leaders whose names are mentioned above, 
as well as to the Wakefield Waterworks Engineer (C. Clemesha Smith, Esq.) 
and the L.M.S. Railway Co., for permission to visit their respective 
properties. 
In a district so thoroughly worked not much new material was expected . 
In view of the inroads on nature made by the march of industry, a list of 
the plants actually seen on this date, contributed by Mr. E. Hallowell 
with the assistance of Messrs. Kaye and Fielding is worthy of being placed 
on record.

To these flowering plants Mr. Hallowell writes, “I would like to add 
Claytonia sibirica, which has spread down the valley for many miles since 
its appearance probably some thirty years ago. I have no doubt what 
ever that the plant was thrown into the river at some point and 
immediately began to make itself at home along the banks.

addition, to the flora V.C. 63 . Lentinus lepideus, growing on the creosoted 
timbers of the platform at Sowerby Bridge Station, was collected by Miss 
D. Wooff. The mould Monilia alphitoides, on Oak, was very prevalent 
in the district.
