Table IV gives the results of treatment with atoxyl and lactate of mercury, 

 which are less good than those with succinimide and soziodolate of mercury. 

 This drug has the disadvantage of being very irritating to the tissues, and 

 also of forming a precipitate when mixed with atoxyl. The solution used 

 was the ordinary hypodermic solution (2*5 per cent.) prepared by Martindale.
