bling Mr. Perkin’s anthrapurpurine. Isoanthraflavine when 
treated in the same way yields a body which has most of 
the properties of anthrapurpurine, though it seems to crys- 
tallise more readily and in longer needles than the latter 
substance does, according to Mr. Perkin’s account. We are 
at present engaged in the investigation of these products. 
Professor Boyd Dawkins, F.R.S., made the following 
remarks : 
It is not my intention to add more than a few necessary 
words to the literature, serious and comic, which has Windy 
Knoll for its centre. At the last meeting I was unable to 
give a decided ' yes’ or ' no’ to Mr. Plant’s evidence that the 
^ bone of contention’ was not that of bison, because it is a 
fragment of a variable and unimportant bone which I had 
not seen for nearly two years. I have re-examined the 
evidence, and consulted Mr. Davies, of the British Museum, 
and I find that I was mistaken in referring it to bison. The 
mistake is however a side issue and not of any scientific 
importance, because the remains of that animal from that 
place are considerably over one thousand in number, while 
those of the bear are over sixty, 
With regard to the real point at issue, as to whether it 
adds the cave-bear to the fauna of Derbyshire, as urged by 
Mr. Plant, I have only to add to the opinion expressed in 
Proceed, of Lit. and Phil. Soc., Manchester, 1874, p. 6, the 
views of Professor Busk and Mr. Davies. The former 
writes — I should be very loth to give any opinion what- 
ever as to the specific characters of a fossil bear from that 
part of the skeleton alone.” The latter, after regretting 
that Mr. Plant had omitted to mention the discovery of the 
associated ursine jaws and teeth when the bone was sub- 
mitted to him, says (25th March, 1876), “I have not suffi- 
ciently studied the bones of the bears, with the exception 
of the jaws and teeth, as to enable me to determine with 
certainty the species to which they belong. Had I known
