one from the Richmond River, N.S.W., and the other from 
Santa Maria, California. Dr. Morris read some notes on 
encisted Filaria, found in the flesh of the bullock, and exhibited 
the cyst and portions of the mature and embryo worm under the 
microscope. The cyst is formed of dense white fibrous tissue, 
encased in which is found the mature worm with interlaced meshes 
of tissue corresponding with the folds of the worm. The cyst is 
about the size of a large Barcelona nut, and many contain more
