Arrived at the end of my dissertation I have only to request that it may be received 
with forbearance, for no one can feel more sensibly than myself how much it falls short 
of being complete. 
This Monograph, like all human works, has its wants and faults, some of which 
might have been avoided if I could have had daily access for a year to the scientific 
materials in Europe from which to make the necessary recapitulations. 
The only thing which renders this Monograph of value is, that I have reduced the 
three subfamilies of Bonaparte, the four of G. R. Gray, and the five of J. Cassin into 
two natural subfamilies of Day and Night Owls, and that I have degraded to the rank 
of subgenera eleven genera which have been adopted by late authors as true genera. 
In order to guard against the fault of too great subdivision, I first distinguished the 
species, and then looked for the characters of the small subgenera. After fixing the 
limits of the subgenera, there was no difficulty in arranging them according to their 
true genera.
