of flint flakes that were to be found in the Yorkshire Wolds, a ^ in * 
Staffordshire Potteries, where flints were imported from all pa , 
diversity of shape among the unworked flints was most wmartaU*. 
Mr. Callard said he had purchased, in 1871, one of the ^which 
had been referred to in the paper, as from an original fount i 
Cavern, and when he was in the cavern in 1875 he saw similar casts s 
being sold. Of course he knew that Mr. Pengelly had no w sh to impose 
upon the public*— but had only been rather injudicious m these ^ 
matters, in which the greatest amount of care was necessary , a 
all the care that could possibly be taken, mistakes would con mu ^ 
It certainly was a very dangerous experiment for a gen em u _ 
Pengelly to lend the person who was going to exhibit the ca » 
formed flint, to show visitors what a flint-knife was like. 'J US AN1 ‘ 
be expected from such a circumstance, was what had really taUn f aC 
to the production of flint flakes, change of temperature would do that. 
On one occasion he (Mr. Callard) received a piece o m , an 
a stream of iced water over it, and the most perfect little ■ 
were produced, without the application of any blow oi crusl g 1 
whatever. gaid he had not had the advantage of seeing the 
Brixham Cavern, but he had seen some of the specimens taken from «, 
and the whole question really amounted to this, whether the h teen 86 e J hat 
flints gave evidence of human manufacture or not, and whet er 
did afford such evidence were found in the right cave, lying ni. i e 
of the mammoth. Some of the specimens certainly had impressed him 
with the belief that they were produced by man, but otheis ner 
contrary opinion ; and who was to decide? . , , 
The Bishop of Melbourne thought the Institute was great y m 
to Mr. Whitley for his paper, for it was very important that scienti c men 
should examine these things before they questioned the Word of Co . _ 
own conviction was, that when the facts which were alleged were inquired 
into, they would not be found to lead to the conclusions which were foun e< 
upon them. He had been waiting for some time and with some degree o 
anxiety, to learn what conclusion scientific men would come to n i i legan 
to these flints, and he confessed that he was glad to find that the evidence 
of human workmanship could not satisfactorily be made out. 1 r. u ey 
had shown that at least a very great degree of doubt existed, as to me lei 
the flints were of human manufacture or not, and his arguments were sue l 
as, at any rate, to prevent many people from adopting the conclusions w lie i 
some scientific men of the present day had arrived at.
