TROCHEE, Troch^us, formed of r^ix'--'> I run, be- 

 caufe it moves quickly, in Greek and Latin Poetry, a kind 

 of foot confifting of two fyllables, the firft long, the latter 

 fhort : fuch as the words -vade and muja. 



The trochee is the reverfe of the iambus, and has juft a 

 contrary effeft ; the latter being hght and fprightly, and 

 the former weak and languid, as all thofe meafures are which 

 move from a long to a fhort fyllable.

 fongs and dances. Thefe give the denomination trochdus to 

 the tribrachys. Quint, lib. x. cap. 4.

 t°gyy a genus of birds of the order Picae ; the charafters of 

 which are, that the bill is longer than the head, fubulate-

 form, confifting of two conjoined flips forming a tube, and 

 extenfile ; the legs flender and rather fliort, and feet formed 

 for walking ; the tail compofed of ten feathers. 



The humming-birds conftitute a livet)' briUiant race, dif- 

 tinguifhed by their beautiful colours and diminutive fize, 

 peculiar natives of the American continent and adjacent 

 ifjands, and, with few exceptions, confined to the hotter re- 

 gions. The genus is extenfive, and it has therefore been 

 found convenient to divide them into two feftions, -vix. the
