Glycogen in Sporozoa.* — Brault and Loeper describe in the rabbit 

 infected with Goccidium oviforme a blocking of the bile canals with para- 

 sites. The young parasites were attached to the cell walls ; the cells 

 died off by degrees, and no sign of their actual invasion was observed. 

 The coccidia at this stage were abundantly provided with glycogen, 

 which they gradually lost as soon as they became encapsuled. The 

 coccidia cause stretching of the bile canals, so that sometimes they are 

 ruptured and the coccidia gain entrance to the blood vessels and are 

 thus distributed.
