EXPLANATION OF FIGURES 



8 'i\vo cells of the corpus striatum. They contain spherical and rod-shaped 

 mitochondria which, in fact, resemble closely the fine meduUated fibres cut in 

 section in the neurophil about them. To the left two red blood cells are to be 

 seen in a capillary. 



9 Large pyramidal cell of the cortex cerel)ri with its contained mitochondria 

 which are quite filamentous. This cell also is emlsedded in a mass of fibers which 

 are cut in section and which resemble mitochondria very closely. 



10 A cell from the septum. 



11 Large cell from the formatio reticularis of the mid brain. The mito- 

 chondria are thread-like and remind one of those which occur constantly in an- 

 terior horn cells. They are, as is invariably the case in all the cells studied, 

 more filamentous in the processes than in the cell body. 



12 Purkinje cell of the cerebellum with neighboring granule cells just be- 

 neath it. The mitochondria look like minute bacilli near the nucleus but they 

 become elongated as one proceeds toward the great dendrite. The granule cells 

 also contain them. The black dots in the molecular layer are cross sections of 

 fibres.
