Percutaneous galvanization of the brain produces a variety of 
symptoms. Faradization of the veins causes vomition and 
arrests peristalsis, while galvanism induces quiescence of the stom¬ 
ach. Galvanism of the eye, especially kathodic, induces flashes 
of light of the tongue and nose, subjective tastes and odors, 
respectively. 
The fact that morbid alterations in the tissues affected their 
electrical phenomena gave birth to a permanent factor and prac¬ 
tice in medical science—“ Electro-Diagnosis ”—which requires a 
comparison of symmetrical parts where disease is unilateral, and a 
comparison of some ether part of the body whose reaction is defin¬ 
itely known when disease is u bilateral.” In either case pathogno¬ 
monic results may be obtained. Further, the seat of disease may 
be localized by the “thermo-electric pile,” which possesses a super¬ 
acute sensitiveness to variations of temperature. This fact has 
a bearing upon* the “cerebral localization hypothesis,” and upon 
the diagnosis of obscure lamenesses in the horse. 
A few brief remarks upon electro-therapeutics and surgery 
will conclude this crude paper. 
In practice, good results accrue from the tonic effects of the 
local withdrawal of sparks from the affected parts in exhaustion, 
debility, muscular and chronic rheumatism, stiff joints, neuralgia, 
gastralgia, torpid liver, dyspepsia, constipation, etc. Whether 
this action is entirely reflex or direct, or both, it is yet uncertain. 
The size of electrodes is a point to be considered. The current 
is stronger and more dense at the smaller electrode. For a small 
superficial motor point use a small electrode, with a larger one 
at a distance. For a larger part use large-sized electrodes close 
together. For a large joint or a deep-seated part, such as the 
bladder or brain, place large terminals on both sides of the part, 
so that the current will cover the area. For the stimulation of 
the bladder or rectum, however, I consider spinal-eleetralization 
all that is necessary, because in treating paraplegia incidental to 
indigestion, spinal ansemia, etc., defacation and urination will be 
found to be early and significant responses to the life-sustaining 
fluid. Avoid unnecessary pain by a gradual increase in the 
strength of the current and by a firm and uniform pressure of
