Spurzheim, published in London in 1816*. The 

 circumstance is merely mentioned here, as it affords 

 additional proof of the migratory nature of the swal- 

 low tribe. Indeed, when we consider the number of 

 birds of different genera known to change their habi- 

 tations across the seas, it seems rather surprising 

 that the migration of the swallow should even have 

 been particularly doubted. The ancients, as will ap- 

 pear in the following pages, were acquainted with 

 it, and the precise origin of the contrary opinion 

 seems doubtful. 



* According to the new discoveries, there is a systematic corre- 

 spondence between the character and the brain in all known animals. 

 Among birds, for example, the cuckoo wants the organ of attach- 

 ment to its offspring, the falcon tribe have the organ of destructive- 

 ness, &c. &c. and so on of other species, according to their cha- 

 racter. Vide the Physiog. Syst. of Dr. Spurzheim, above alluded to.
