JUBILEE MEETING. — ^PROFESSOR JUDD.

does not include geology, then other sciences ought to be specified 
as well. I think the explanation of this apparently anomolous desig- 
nation will be found in the fact that originally this society was " The 
Geological and Polytechnic Society of the West Biding of Yorkshire; " 
and the district of the West Riding is one so rich in mineral 
deposits — deposits of ironstone, coal, limestone, and building stone, 
that the science of geology which deals with questions relating to 
such deposits, was thereby brought into special prominence, and the 
name geological was added to that of polytechnic. Whether I am 
right or wrong in this attempted explanation of the origin of the 
name, I cannot but feel that I am not far wrong in ascribing to this 
circumstance the honour, and 1 will add, the great pleasure of 
receiving an invitation to be here to-day. It is, I know, as the 
representative for the time being of a great central society whose 
work is to investigate "the mineral structure of the earth" that I 
am here to-day — a society which has always taken the greatest 
interest and has always cultivated the most friendly relations with 
the Yorkshire Geological and Polytechnic Society, and I am per- 
suaded will always continue to do so. (Hear, hear.) During the 
present year a great number of individuals have been called upon to 
exercise a considerable amount of ingenuity in seeking to discover 
either wonderful parallels, or striking contrasts, between the years 
1837 and 1887. And it arouses in one almost a sense of personal 
injury to find that there is another jubilee— that of your society, 
dating from the same period, which seems to demand further 
exertions of the same kind. (Laughter.) But glancing at the 
history of the progress of science, a suggestion does present itself at 
the very surface as affording subject for profitable reflection — the 
date of our society does correspond very closely indeed with a crisis — 
a turning point in history of science Before that date the 
advancement of science was almost exclusively due to the efforts of 
individuals. Since then, though the efforts of individuals have never 
been wanting, yet the efforts of individuals have been to a great extent 
supplemented and correlated by the labours of various scientific bodies 
like our own. Very strikingly does this appear if we study the history 
of the progress of geology in Yorkshire since 1837. Before that date
