‘At 7 a.m. on January 19, 1897, G., aged 22, was going along 
a footpath near Trouvaillant, when he was bitten in the left 
external malleolus by a Trigonocephalus which was rutting (a cir- 
cumstance which, according to the natives, aggravates the character 
of the bite). 
“ After killing one of the reptiles (the other having escaped), 
the young man made his way to the detachment of gendarmery 
stationed close by. The officer in command applied a ligature 
to the upper part of the leg, cupped the man a few times, and 
sent information to us at the Military Hospital. On reaching 
the spot at 9.15 we found, on the postero-inferior surface of the 
left external malleolus, two small wounds resembling those caused 
by the bite of a snake. The leg was swollen and painful, and the 
patient could hardly put his foot to the ground. 
“ At 9.30, after taking the usual antiseptic precautions, we gave 
an injection cf Calmette’s anti-venomous serum, from a bottle 
dated December 26, 1896. Not having any hypochlorite of calcium 
at our disposal, we washed the wound with a 1 in 60 solution of 
hyposulphite of soda, and applied a dressing of carbolic gauze. An 
hour later the patient was taken to Saint Pierre in a carriage. 
Temperature 372° C. No vomiting, or tetanic phenomena. In 
the afternoon the pain was less acute, and the cedema seemed 
to have diminished a little. Mercurial ointment rubbed in. 
“Four days later the patient, being cured without having had 
the least rise of temperature, proceeded to the country. 
“This case is interesting, since a single dose of antivenomous 
serum (20 grammes), injected two hours and a half after the 
accident, sufficed to cure a young man bitten by a Trigonocephalus 
measuring 1 metre 20 cm. in length.” 
M.—Crotalus horidus.
