of a partial Obstruction of the Circulation. 495 



The following case is given as affording a description of the 

 usual course of this distressing disease, in the words of the 

 patient. 



Case VII. — Callykissore Chatterjea, a large and strong 

 youth, aged 19 : states — " I have been afflicted with this com- 

 plaint from my infancy, and it seems to increase as I advance 

 in years. No member of my family has had this sickness, 

 with the exception of my youngest sister. The intervals of 

 the attacks are diminished, but during the cold months it is 

 not so troublesome as it is during the rest of the year. In 

 the hottest days, the perspiration from the palms of the 

 hands and soles of the feet, is so copious, that I cannot em- 

 ploy myself in reading or writing, sometimes for a whole day. 

 The perspiration on such occasions drops from my fingers for 

 hours. At night, and during damp and rainy days, it is not 

 so troublesome, nor occurs so frequently. During the hottest 

 time of the day, I feel a burning sensation in my hands and 

 feet. In the mornings and nights the hands and feet are of 

 the same temperature as the other parts of the body, but 

 as the day advances, the heat of these parts increases. 



22nd June. — Compressed the humeral artery for six mi- 

 nutes ; the veins were allowed to swell out, when the arm 

 felt benumbed, cold, and livid. 



23rd. — Compression for twenty minutes ; numbness and 

 uneasiness from the stoppage of the circulation. 



24th. — Better : perspiration in the hand yesterday di- 

 minished. Again applied the tourniquet for the same time as 

 yesterday. 



Sth July. — Better : the palms still perspire. Temperature 

 of air 83°, pulse before experiment 82 ; after the ligature had 

 been applied some time, the temperature of the hand of the 

 compressed side was 88° ; in the axilla beyond the ligature, 

 97° ; in the opposite axilla, 99°.
