The experienced ornithologist need hardly be re- 

 minded, that when two groups are compared whose 

 rank and situation are either remote or very dissi- 

 milar, the analogical resemblances between them 

 will partake of the same remoteness; hence it 

 sometimes happens, that although they agree suffi- 

 ciently strong in some parts to make us feel suffi- 

 ciently confident that the analogies are just, yet 

 others will be so obscure that their correctness can 

 only be established by a line of inductive reasoning, 

 and their mutual relations come to light through 

 the instrumentality of other groups. Applying this 

 undoubted fact to the foregoing table, we shall find 

 some of the analogies more apparent than others ; 

 and we are therefore to inquire, how far those 

 which seem the most remote can be placed on the 

 ame degree of probability with the others. There 

 can be no doubt, for instance, that the true fly- 

 catchers, forming the genus Mustietpa> are th%
