ACROMEGALY. HYPERTROPHY OF THE PITUITARY 



BODY. 



Like other portion.s of the brain the pituitar}- bod}- is subject 

 to degenerations and diseases of various kinds. This is particu- 

 larly mentioned here because of the occasional a.ssociation of its 

 h3^pertrophy with the trophic processes of different parts of the 

 body. Along- with an over-development of the limbs, and less 

 frequently of the body, an enormous increase of the hypophysis 

 has been found, and the one condition has naturally been set 

 down as the result of the other. In some such instances, of over- 

 growth, however, some other blood glands, such as the thyroid 

 or thymus, have been found to be hypertrophied, so that at 

 present it is difficult to do more than notice the association ob- 

 served between the two conditions. 



CEREBELLAR DISEASE. 



Cerebellum and coordination. Pressure on adjacent parts renders results 

 uncertain. Generic symptoms, ataxia, titubation. Marked symptoms with 

 rapid morbid progress. Treatment : tonic, hygienic. 



Whatever functions are exercised b\^ the cerebellum there is 

 no doubt of its control over nuiscular coordination. It is quite 

 true that disease of any other part of the brain causing effusion, 

 exudation or intracranial pressure will more or less completely 

 arrest the functions of the cerebellum ju.st as disease of the cere- 

 bellum producing intracranial pressure will derange the functions 

 of other parts of the encephalon. The general symptoms pro- 

 dticed in this wa}' cannot therefore be accepted as indicating the 

 precise localization of an intracranial disease. Dullness, stupor, 

 coma, dilated pupils, choked discs, optic neuritis, and vomiting, 

 are in this sense generic symptoms, which may in the absence of 

 fever indicate dropsy, exudation, apoplex}', tumor, concussion or 

 other lesion, and with hyperthermia ma}- indicate encephalitis or 

 meningitis. But if in the absence of these symptoms and of aural
