Cryptocystis , and the suppression of the budding of the caudal vesicle 
in true cysticerci, are explained by the enunciation of the law that the 
complication of development and of organization are in inverse ratio to 
one another. 
Ziegler (22) finds that the cercariae of Bucephalus , after escaping from 
the freshwater mussel, most often make their way into the Rudd ( Leu - 
ciscus erythrophthalmus ), but the next host that eats the Rudd is not yet 
known. 
Braun (1) reports on some successful experiments on human subjects. 
The direct reproduction of Tcenia is exemplified by a case reported by 
Megnin (13), who observed in a watched dog small specimens of T. sen'ata , 
which he thinks must have been developed from ova of larger specimens 
found in the same animal.
