branchia in the fact that the torsion of the body has 
caused the obsolescence or abortion of one of the true 
gills, and for this reason Dr. Lankester has arranged them 
under one ordinal head, Azyrjobranchia..

lar arteries. Azygous veins, three veins of the trunk, 
one on the right side and two on the left. The rii/ht m- 
large azyyoux vein arises in small branches from the up- 
per lumbar vertebne, passes up into the thorax to the 
right of the aorta, and, receiving the eight inferior right 
intercostal veins, the lesser azygous veins, the left supe- 
rior intercostal vein, the right bronchial vein, and some 
esophageal and mediastinal branches, empties into the 
superior vena cava just above the pericardium. The left 
luirer or small azyffoits vein begins in the upper lumbar 
veins, enters the thorax, receives the four or five lower 
left intercostal veins and some esophageal and medias- 
tinal branches, and empties usually into the right azygous 
vein, but sometimes into the left innominate vein. The 
left ttini'T ^y/ii/.v i-i'in is derived from the left intercostal 
veins, which lie between those that empty into the left 
superior intercostal trunk and those that empty into the 
left lower azygos. They are usually two or three in num- 
ber. It communicates above with the left superior inter- 
costal vein and below with the right azygous vein. 
azym, azyme (az'im), n. [< LL. azymus, also 
azymon, unleavened bread, < Gr. aCu//of, neut. 
a^vuuv, unleavened, < a- priv. + ^'vfiij, leaven, 
< fen>, boil, bubble, ferment.] Unleavened 
bread, or a loaf of unleavened bread; espe- 
cially, the bread eaten among the Jews at the 
time of the Passover, or that used in part of 
the Christian church for consecration in the 
eucharist: generally in the plural. In the West 
em Church azyms seem to have been used as far back as 
positive testimony goes, but the evidence either for or 
against their use in the earlier centuries is very scanty. 
In the Eaateru Church consecration of leavened bread 
seems to have been the universal rule since the earliest 
times, but some early Oriental sects used azyms. The 
Latin Church does not hold that the use of leavened 
bread Invalidates consecration. The controversy between 
the Eastern and Western churches as to azyms turns 
mainly on the question whether the Last Supper was w ith- 
in the period of unleavened bread, and whether therefore 
the holy communion was instituted with azyms or not. 
We have shunned the obscurity of the papists in their 
azyrnes, tunlck, &c. 
The Translators of the Bililt to the Rm.lrr. 
Rome prescrites nothing to other nations on the point, 
merely laying down that the blessed Sacrament may more 
conveniently be consecrated in Azvmes.
