of the mouth of many birds, as flycatchers, 
goatsuckers, and others. When very long, as In the 
goatsucker, they are sometimes called vibrimr pectinattr, 
and may have lateral filaments, as In the chuck-will's 
widow. The use of the vlhrisftte Is supposed to lie to en- 
tangle the legs and wings of Insect*, and thus diminish 
or prevent their struggling when caught, as the hrlslles 
are observed to be specially well developed in insectivorous 
birds which take their prey on the wing. See cuts under

string or rod, the vibrations are distinguished a* traiu- 
vene or longitudinal, according to the direction of the 
oscillating movement relatively to the length of the sono- 
rous body. The term vibration is also applied to the 
motion (generally an elliptical revolution) which is pro- 
duced among the particles of a fluid or ethereal medium 
when their equilibrium is disturbed by any linpulse, by 
which means waves or undulations are caused. In all 
cases one complete vibration means the double movement
