VENOM OF SNAKES. 121 



(6) Solution of l/60th hypochlorite of lime. The technique is 

 the same. A few injections around the wound — afterwards 

 dress as in case (a). 



(c) 1 /80th solution of hjrpochlorite of soda, 1 /lOO of chromic acid, 

 1/100 of gold chloride. These have the disadvantage of 

 being caustic, and may sometimes give rise to ulcers. 



(4) Make an injection of anti-ophidian serum. The right dose 

 varies with the serum employed. With Calmette's serum it is 

 necessary to inject at the outset at least 40 cc. (and not 10 or 20, 

 as the author advises). The general technique remains the same. 

 A sterilized syringe (of 20 cc. capacity) is filled asepticly with the 

 serum chosen and the liquid is injected into the sub -cutaneous 

 cellular tissue in the side of the patient. It is naturally indis- 

 pensable (as for every hypodermic injection) to wash carefulh^ with 

 alcohol the skin of the region where the puncture has to be made. 

 The place is then touched with a plug of aseptic padding dipped in 

 tincture of iodine. When all the liquid has penetrated, the needle 

 is pulled out with a jerk and a small piece of sterilized padding is 

 applied and kept in place with collodion. 



(5) Remove the ligature. Give warm tea or coffee, and prevent 

 the sensation of cold by wrappmg up the patient in warm blankets.
