PATHOLOGY OF NUTRITION. 



arranged in regular bundles and their nuclei are not oblong, 

 but oval ; sarcomatous transformation, however, may occur. 

 Myxomatous degeneration and calcification are the most fre- 

 quent retrograde changes to which they are liable.

Neuroma and Glioma. 



A true neuroma is a very rare tumor, composed of nerve- 

 fibres and ganglion-cells. The so-called false neuromata are 

 usually fibromata occurring in the course of a nerve and 

 found also as bulbous swellings of the cut ends of the nerves 

 in amputated limbs. 



A glioma is a tumor composed of tissue similar to neuroglia, 

 occurring in the brain and less frequently in the spinal cord 

 and the retina of the eye. They are formed of a very delicate 

 network of fibres, imbedded in which are numerous round 

 or oval cells with very large nuclei. They are benign, though 

 liable to undergo sarcomatous transformation.
