limbs still persisted; they had been ill for more than a year. However 

 they were able to walk, provided that they used two sticks, but they 

 did not need crutches. It was evident that it was difficult to them to 

 lift their feet, and they did so only as much as was absolutely 

 necessary. 



I tested the sensitivity and found a marked weakening on both 

 sides of tactile sensitivity, sensitivity to heat and cold, and sensitivity 

 to pain. 



All the other mechanisms and all the other functions were normal. 

 I observed, however, a little anemia in Yanni, but it had no connection 

 with the paralysis; in 1868, he had had obstinate intermittent fevers, 

 from which he had recovered only a short time before I saw him. 



The muscles of the lower limbs were not manifestly atrophied. 

 These two men continued to use the diving suit. They resumed their 

 work, one in the month of October, 1868, the other in the month of 

 May, 1869, and they found that walking was easier in the water than 

 in the open air. 



In the month of January, 1870, their condition was unchanged.

Next comes a series of 9 observations, in which 2 divers died 

 very quickly, one after twenty-four hours, the other after three 

 months, from the sequelae of paraplegia. The last five recovered 

 more or less completely. I reproduce in full these observations, 

 which are very brief: 



I. June 23, 1868, at Navarin, Jorgieos Koutchouraki, who had gone 

 down to a depth of 40 to 45 meters, remained on the bottom for a 

 quarter of an hour. According to the custom of Greek divers, he had 

 himself hoisted up after this time; he reached the deck of the boat in 

 perfect health; a few minutes afterwards, he complained of dizziness, 

 and fell upon the deck. Loss of speech and intelligence; face red; 

 sudden death. 



II. July 10, 1868, in the Greek Archipelago, Manolis Couloumaris, 

 went down to a depth of 25 fathoms, that is, about 40 meters, and 

 remained on the bottom about three-quarters of an hour. He then 

 gave the signal agreed upon and was hoisted up. He had been on deck 

 about a quarter of an hour, and, according to his comrades, he was 

 squeezing out the sponges which he had brought up, when he was 

 suddenly attacked by severe pains, and almost immediately by com- 

 plete loss of consciousness. He rapidly succumbed. 



III. June 15, 1869, on the coast of Bengasi, a man by the name of 

 Joannis Xippas went down 20 fathoms, that is, 30 to 35 meters. This 

 diver had gone down five days in succession, and several times each 

 day, in depths always more than 30 meters, and until that time had felt 

 no symptoms, except a little pain in his left arm. June 15, he had 

 gone down for the second time when the attack came. Coming up 

 after a stay of more than a half-hour, at first he did not seem ill, 

 and went down to the deck of his caique to rest. Only an hour after- 

 wards one of his comrades, going down to him, found him uncon-
