THE DIGNITY OF CHEMISTRY.* 
CHEMISTRY as a profession may be said to 
have completed its hundredth year, and we 
have met to-night to celebrate the quarto- 
centennial of chemical organization in 
America. 
In our democratic country, all attempts 
to create a class or caste should be dis- 
couraged, especially if the attempt be made 
to endow the class with unusual or special 
privileges. We have no place for an he- 
reditary or purchasable aristocracy, but in 
the function of the civic body there must 
be specialization, and those individuals who 
by choice or fortuitous incident devote 
themselves to special duties are brought 
together by occupation, by congeniality 
and by desire for mutual helpfulness and 
improvement. In this mutual attraction 
we find the genesis of all trade and pro- 
fessional organization. The aggregate is 
always stronger than the segregate. This 
unity of purpose and this conformity of 
effort become reprehensible only when 
autocratic, imperative and insolent. The 
assumption of superior virtues, the asser- 
tion of peculiar privileges and the inter- 
ference with the rights of others are never 
to be advocated nor condoned.

ical Society, April 12, 1901, on the occasion of the cele- 
bration of the 25th anniversary of the founding of 
the Society.
