CASE I. 



About three p. m. on the— of Novemberj a nitive woman in crof- 

 fing near the land cuilboihouTe was feen whilft ftepping out ©f the" 

 water to fliake off fomething which grafped her foot, and which to fe- 

 veral people who were looking on appeared diflindly to be a water 

 fnake, the woman after having advanced a few paces from the river 

 fell down, and was carried to the Pandaul in a ftate of apparent infea- 

 iibility : on examining her feef, two fraall Hut diftind: wounds were 

 formed on the ankle of the right leg, her fkin was cold, her face livid, 

 fhe breathed with great difficulty and with an occafional hickup and 

 her pulfe at the temple or wri{ls was fcarceiy to be felt : a ligature was 

 immediately applied above the wound previoufly enlarged with a Ian- 

 eet, and to which a piece of the^'carbonate of ammonia well moiftened 

 with the pure nitric acid had been applied ; thirty drops of the Eau-de- 

 luce in a glafs of water were adminilkred nearly at the fame time that 

 the other means were taken : in five minuies more a- {imiiar dofe \-vas 

 poured down her throat; this laft leenied rather to er^creafe the fpafm 

 at the cheft, but the pulfe now v/as felt feebly, though diftindly at the 

 wrift—the third dofe was repeated in three minutes more, and upon 

 fwaltewing it, ilie ferearned 'and evidently 'breathed more freely;.
