strangest of all, that of the magnet’s influence, we must assume 
that it, like the static electricity of the plate electric machine pro- 
duces with its high tension a state of extreme hyperaesthesia, or 
impressibility, so that the impression made upon the sensory centres 
from the right arm irritation, is now great enough to excite through 
the commissural fibres the same reflex action on the left side. But 
further, it was found that on removing the tourniquet from the right 
arm the contractures of the left gradually relaxed, and the con- 
tractures came back again in the right arm, but slowly and not very 
completely. 
We must confess that we have present what seem to be at first 
two contradictory phenomena: (a@) anaemia producing hyper-excita- 
bility in one arm, (6) while in the other tonic magnetic influence has 
produced, at least as far as effects go, a similar state of great 
‘Sensibility. 
But though we may fail in fully explaining this peculiar condition, 
yet I think we can gain at least one step in advance by noticing an 
explanation given by Dr. Broadbent concerning some of the causes 
of paralysis from hemorrhage into the corpora striata and thalami 
optict. He thinks it can be shown that where the muscles of cor- 
responding parts of the body constantly act in concert the nerve 
nuclei of these muscles are so connected by commissural fibres as to 
be pro tanto a single nucleus. Now supposing that the magnetic 
influence has greatly mereased the impressibility of the left side we 
may fairly infer that the reflex action setting forth from the sensorial 
nucleus which was impressed by the irritation on the right side, and 
which caused the tonic contraction of muscles in the right arm (being 
-of a certain quantity which we may call x), has been transferred to 
that muscle having the greater temporary conductibility. Thus we 
have now relaxation in the muscles of the right arm, and the pheno- 
menon of tonic contraction in those of the left. Let us now remove 
the temporary stimulus of the magnet and we have the original im- 
pression made upon the nucleus, again transferred to the right arm 
but in a greatly diminished degree, since this side has again become 
that of greatest excitability. é 
Before closing there is another condition induced in patients whilst 
in the hypuotic state so strange—we might say marvellous—and 
unusual that it demands some few remarks. I refer to the remark 
already made that, when the one eye of a hypnotized patient is
