to sell his place to a person qualified to act, and of whom there 
are always many waiting such an opportunity; he is himself 
irrevocably dismissed from his vocation. 
Having thus described the details of the regulations to 
which the apothecary in Germany is subjected, the result is 
capable of being conveyed in a very few words. He becomes 
the fellow labourer, but not the rival, of the physician. His

look to any meeting of the German Association of scientific 
men, we find an independent section for pharmacy; and we 
likewise see that the great mass of the work of the chemical 
and botanical sections is accomplished by persons, who, if not 
apothecaries, were originally intended to be such, had not 
their talents and love of science carried them to a higher 
sphere of action.

indigo colour, but which disappears rapidly by the deposition 
of an enormous quantity of carbon. The same acid, diluted
