PLATE V. 



Plasmodium of Badhamia tdricularis. x 2. (Photographed from nature.) 

 The whole of the network of veins here shown was formed in one night between 

 11 p.m. and 7 a.m. It was developed from a small mass of plasmodium about 

 half an inch in diameter which occupied a position a little to the right of the 

 bulb at tlie base of the illustration. The material was placed in a moistened 

 cell, when, in its search for food, it rapidly developed pseudopodia connected by 

 anastomosing veins. It formed two centres of development of the branch systems, 

 which united at the points of contact, as seen in the illustration. The transverse 

 cracks in the principal veins are due to shrinkage from the effects of alcohol, 

 with which the organism was killed.
