Diving Bells and Suits 365 



Second Category. Workmen who worked only above 2.9 atmos- 

 pheres. 



I. No effect. 



II. Only muscular pains in the left thigh, which yielded to cold 

 water. 



III. IV. Nothing. 



V. Moderate muscular pains, but persisting from one shift to the 

 next; recompression relieved them immediately. 



VI. Nothing. 



VII. 28 years old. Athletic. Pressure of 3.8 at the beginning. After 

 10 days, loss of consciousness, violent lockjaw. Rapid pulse. 



Reddish bleeding eight hours afterwards, purging, blisters. 



Two days after, consciousness suddenly returned: the patient 

 opened his eyes, seemed to awaken from a dream, said a few aston- 

 ished words. 



Recovers, but remains extremely deaf. 



Third Category. Workmen who began at 4.154 atmospheres. 



I, II. Nothing. 



III. Had previous hemoptysis. Improvement. 



IV, V, VI. Nothing, except rather severe muscular pains. 



VII. 40 years old. Very robust. Went down into the shaft only 

 once. On coming out (decompression in twenty minutes) died almost 

 immediately. 



Autopsy held 36 hours after death: generalized subcutaneous 

 emphysema (existed before putrefaction began, the authors note) ; 

 nothing in the meninges, in the brain, or the cerebellum; congestion 

 of the lungs with generalized darkish tint (underlined by the authors) ; 

 blood fluid and dark in the heart; liver, spleen, and kidneys congested. 



VIII. Nothing. 



IX. Moderate muscular pains. 



X. At his first trial, very severe muscular pains, persisting for 

 several days. Discharged. 



XI. Same. 



XII to XIX. Nothing, except insignificant muscular pains. How- 

 ever, they sustained the pressure of 4y 4 atmospheres for three 

 months. 



XX. At his first trial, too rapid decompression. A few minutes 

 after his leaving the lock-chamber, looked like a corpse: face pallid, 

 icy cold, eyes dull, pupils enormously dilated, respiration uneasy; on 

 listening to the heart, heard only a vague quivering; pulse impercep- 

 tible; perception gone; involuntary urination; dark vomit; complete 

 loss of muscular power. 



Warm bath, blankets, friction. After a half-hour, the pulse begins 

 to be perceptible, the respiration is deeper, a little warmth appears 

 in the body; the patient stammers disconnected words. During the 

 night, hardly has warmth been reestablished when acute pains appear 

 in the muscles; keen pains in the head, blindness and deafness; 

 wretched pulse, 50.
