2. To initiate or inaugurate with ceremonies

places " the merry dancers." They assume many shapes 
and a variety of colors, from a pale red or yellow to a 
deep red or blood-color ; and in the northern latitudes 
they serve to illuminate the earth and cheer the gloom of 
the long winter night. The appearance of the aurora bo- 
realis so exactly resembles the effects of artificial electri- 
city that there is every reason to believe that their causes 
are identical. When electricity passes through rarefied 
air it exhibits a diffused luminous stream which has all 
the characteristic appearances of the aurora, and hence 
it is highly probable that this natural phenomenon is oc- 
casioned by the passage of electricity through the upper 
regions of the atmosphere, although under conditions not 
as yet entirely understood. The connection of the au- 
roral displays with disturbances of the magnetic needle is 
now regarded as an ascertained fact. The aurora borealis 
is said to be frequently accompanied by sound, which is 
variously described as resembling the rustling of pieces 
2. In patliol., a method of distinguishing the 
state of the internal parts of the body, particu- 
larly of the thorax and abdomen, by observing 
the sounds arising in the part, either through 
the direct application of the ear to the ad- 
jacent external surface (immediate ausculta- 
tion) or by applying the stethoscope over the 
part and listening through it (mediate ausculta- 
tion). See stethoscope. Auscultation may be used 
with more or less advantage in all cases where morbid 
sounds are produced, but its general applications are : 
auscultation of respiration ; auscultation of the voice ; 
auscultation of the cough ; auscultation of sounds foreign 
to all these, but sometimes accompanying them ; auscul- 
tation of the action of the heart ; obstetric auscultation.

The tribunes were at first elected in the curise, where 
the vote of the poorest citizen was equal to that of the 
most wealthy. But, even here, the patricians, besides 
their great influence, had a negative on all proceedings, 
by holding the auspices. J. Adams, Works, IV. 524.
