Dr. Parry on a Case of nervous Affection. 
period of my first visit. The vibrations constantly existed 
while the arm was in the common posture, the fore-arm and 
hand leaning on the lap. If the arm were stretched strongly 
downwards, the vibration of the flexors ceased, but those of 
the deltoid continued. The arm being strongly extended 
forwards, all ceased ; but returned as soon as the muscles 
were relaxed. The vibrations were of different degrees of 
frequency, and at pretty regular intervals, usually about 80 in 
a minute. They were increased in frequency and force by 
any thing which agitated or heated the patient, and were 
always worse after dinner than after breakfast. The pulse in 
the radial artery was 80 in a minute, and rather hard. That 
in the carotids was very full and strong ; and each carotid ap- 
peared to be unusually dilated for about half an inch in length, 
the adjacent portions above and below being much smaller, 
and of the natural size. I much regret that I find in my 
notes of this case, no inquiry whether there was any coin- 
cidence between the systoles of the heart, and the muscular 
vibrations. The patient’s feet were usually cold, and her head 
and face hot. The feeling in her limbs was much as I have 
above described, except that the sensibility was somewhat less 
acute than it had been, and she complained of a tightness all 
over her head, as if it had been bound with a close night-cap. 
Her sleep was usually sound on first going to bed, but after- 
wards, for the most part, interrupted by dreaming. Bowels 
generally costive: appetite moderate: no flatulency or indiges- 
tion : tongue slightly furred, without thirst : urine variable, 
but generally pale. 
The late Mr. George Crook, surgeon, was present while 
I made these examinations ; and when we afterwards con-
