more highly granular and consequently darker to transnntted light, 
and the septum less distinct. It also begins to lose its pyriform shape, 
and slowly reverts to its circular form. When full grown it is circular 
and the horizontal septum has vanished, while it is full of large 
refractUe granules and the epimerite has disappeared. fhesc 
trophozoites are usuaUy found in pairs within the stomach and 
adhering to its wall. 
III. THE FORMATION OF THE SPORONT 
The epimerite or rostrum has completely disappeared, and the 
parasite is circular. The next phase seen of this particular parasite 
islhat of the association and encystment of two sporonts. 
IS embedded in the stomach wall, and consists of a thick hbrous 
capsule. The gametes appear as small granules. 1 he ana ogy o 
similar sporonts parasitic in other members of the Arthiopo a s o 
that they are formed in the following manner - ^ 
sporont conjugate and become encysted in their mother tissue 
nuclear spindle is formed from a small portion of the nuc eus o 
sporont and divides, the remainder of the nucleus degenera^ng. 
spindle then produces daughter nuclei by mitosis and t ey g 
divide, until a number of nuclei arc formed which bu o t e su 
of the sporont. Each budded nucleus is then the primary sporo , 
and ultimately becomes the male or female gamete accor mg ° 
sporont from which it was originally derived. let er i 
instance, the male gamete becomes flagellated or not, it is 
to say, but in the specimens examined in this stage no 
ever seen; however, the cephalonts are very difficult to stairi, y 
are surrounded with such a thick fibrous wall. The ma es 
burst their way into the female half of the cephalont, an ere 
die female gametes. „ , tUp 
The cephalont is a very remarkable looking ce em e 
stomach wall. It is large, frequently thirty times the size of a stomach 
epithelial cell, and its two granular, male and ema e, av . 
very characteristic and disifnet. It can be rolled when the 
pressed under the cover-slip, but T have not their 
gametes, as sufficient force to rupture the cepha 
destruction. ___7
