2. In math., that character of a change which 
consists in a passage from one point, state, or 
value to another without passing through a con-

consists in an infinitesimal change of the vari- 
ables not being everywhere accompanied by 
an infinitesimal change (including no change) 
of the function itself. An essential discontinuity is a 
discontinuity in which the value of the function becomes 
entirely indeterminate.

The term discontinuous, as applied to a function of a 
singlevariable, has been used in two to tally differentsenses. 
Sometimes a function is called discontinuous when its

possess, like other 
hydrozoans, of sting- 
ing by means of their 
thread-cells. The 
hydrosome consists 
of a single umbrella- 
like disk, by the 
rhythmical contrac- 
tion of which the 
creature swims, and 
from the center of 
which hangs a single 
polypite or digestive 
individual, or, less 
frequently, several. 
They are free-swim- 
ming oceanic ani- 
mals, whose body 
consists of such soft 
gelatinous sub- 
stance that a speci- 
men weighing sev- 
eral pounds when alive weighs when dried hardly as 
many grains. The Discophora include many acalephs, in 
the usual sense of that term, and are also called Mfdustf, 
Ephyroineduxw, and Acraspeda. They have been divided 
into Cali/cozoa (lucernarians), Rhizostomea, and Mono- 
stonwa. The term Discophora is also restricted to the 
last two of these, excluding the Lucernarida. Thus, by 
Clans, the Discophora are made a suborder of Sayphomt- 
dusce, synonymous with Acraspeda, and characterized as 
disk-shaped acalephs with the margin of the disk 8-lobed, 
at least 8 submarginal sense-organs, as many ocular 
lobes, and 4 great cavities in the umbrella for the gen- 
erative organs. In this strict sense the Discophora cor- 
respond to the Discomedusce (which see). For several 
wider and inconsistent uses of the term, see the extract. 
The binary division of the Hydrozoa was established 
by Eschscholtz (1829), whose Discophoree phanerocarpa? 
correspond to the Scyphomedusao, whilst his Discophora) 
cryptocarpa? represent the Hydromedusse. The terms 
point to distinctions which are not valid. In 1853 Kolliker 
used the term Discophora for the Scyphomeduste alone, an 
illegitimate limitation of the term which was followed by 
Louis Agassiz in 1860. Nicholson has used the term in 
a reverse sense for a heterogeneous assemblage of those 
medusa? not classified by Huxley as Lucernarida?, nor yet 
recognized as derived from hydroid trophosomes. This 
use of the term adds to the existing confusion, and renders 
its abandonment necessary. . . . The term Discophora is 
used by Claus for the Discomedusaj.

2. In music : (a) The combination of two tones 
that are inharmonious with each other, or in- 
conclusive in combined effect; a dissonance. 
Discord is ... due partly to beats, partly to difficulty 
in identifying pitch. A. Daniell, Prin. of Physics, p. 425. 
(b) The interval between two such tones; any 
interval not a unison, octave, perfect fifth, per- 
fect fourth, major or minor third, or major or 
minor sixth. In medieval music all but the first 
three of the above intervals were at first re- 
garded as discords, (c) Either of the two tones 
forming such an interval, (d) A chord con- 
taining such intervals. See dissonance. 
Why rushed the discords in, but that harmony should be 
prized? Broirning, Abt Vogler. 
Hence 3. Any confused noise ; a mingling or 
clashing of sounds; a harsh clang or uproar.
