To some who are familiar with this by no means uncommon little bird, itmay seem that I am overstating the charm of its melody. I can only saythat the mood I was then in made me somewhat keenly appreciative; also thatI always have never heard any other individual of this species able to produceprecisely the same effect. We know that there are very remarkabledifferences in the songs of birds of the same species, that amongseveral that appear to be perfect and to sing alike one will possess acharm somewhat above the other. The truth is they are not alike; they affect usdifferently, but the sense is not fine enough or not sufficientlytrained to detect the cause. The poet's words may be used of thisnatural melody as well as of the works of art:

"0 the little more and how much it is!"
