682 BERZELIUS ON ORGANIC SUBSTANCES. 
I am not so sanguine as to hope that these views upon the 
difficulties attending the formation of a correct opinion of the 
rational composition of organic substances will be much listened 
to by the supporters of metalepsy. They embrace their theory 
with the full conviction of its infallibility, and little is to be 
effected against blind faith by argument and proof. But I ne- 
vertheless do not despair, that what has here been brought for- 
ward will find some consideration from the great number of 
chemists who have not previously had occasion to declare them- 
selves in favour of any particular view of these questions.
