364 Historical 



VI. Taken to 4V4 atmospheres without accident. One evening, 

 after going to bed apparently well, at 11 o'clock seized by muscular 

 pains accompanied by contractions like tetanus spasms. 



Skin cold, pulse small and slow, urine abundant and clear. Respi- 

 ration uneasy; same results of auscultation as V. 



Baths at 32° so aggravated the pains that the patient could not 

 remain in them. Friction, strong sudation, quiet. Recovered next day, 

 back at work. 



VII. At a pressure of 3.3; cerebral disturbances, like intoxication 

 with coma, hebetude, stuttering. Respiration accelerated, pulse rapid. 

 Pupils dilated. 



Two similar attacks, cured one in nine days, the other in fifteen. 

 Continuance of double vision and vertigo, with deafness oh one side. 

 Discharged. 



VIII. Presented an excessive form of two common phenomena: 

 1. suppression of the functions of the skin and increase of the urinary 

 secretion during the compression: 2. increased rapidity of the heart 

 beats after decompression; his pulse rate rose from 58 to 130. 



IX to XVII. Nothing important to be noted. 



XVIII. Healthy and vigorous. Experienced repeatedly keen pains 

 in the limbs and chest. Respiratory disturbances increasing with the 

 pressure, as well as the muscular pains which were very acute. 



Was discharged. During the last days went down into the shaft 

 without permission. Worked there without complaining; went out 

 with his companions, washed himself like them, immediately fell 

 unconscious and died in a quarter of an hour. Autopsy shows only 

 obstruction of the lungs, congestion of the liver, the spleen and the 

 kidneys; nothing in the brain except gritty congestion. 



XIX. Violent oppression with dullness on percussion and bronch- 

 ophony; rapid pulse, cold skin, continual cough; clonic contractions 

 of the limbs; more sensitive after five hours of treatment. 



Then, at another time, to these symptoms are added: dilation of 

 the pupil, relaxing of the limbs, subdilerium, coma. Three bleedings in 

 rapid succession; blood bright red on leaving the vein; cured. Dis- 

 charged. 



XX. Same symptoms as VII. Also, remained deaf on one side, with 

 vision much weakened. Discharged. 



XXI. One day, sight affected and double, hearing gone; respiration 

 hampered, cough frequent, pulse hard and galloping. Blood red, 

 recovered. 



XXIV and XXV. Nothing important. 



XXVI. Usual thoracic and cerebral symptoms; recovered after 

 profuse sweatings. (P. 250 to 259.) 



Special Category of men who worked only one day and without 

 preparation at 2.8 atmospheres. 



Nine men left the shaft without making any complaint. But 

 shortly afterwards, eight experienced very severe muscular pains, 

 which disappeared during the night, except in one, in whom they 

 persisted several days.
