the constipatory half grain of Sulphate of Lime ; so that the 

 whole practically is inoperative. 



The combination of these salts in nature's proportions 

 would seem to indicate that they must be the best for 

 administration in those ailments to which their use would 

 be beneficial. 



Citrate of Silver is an almost insoluble salt, and requires 

 to be kept from the light, air, and organic matter, it being 

 very easily decomposed. 



A stoppered bottle covered with india-rubber was ex- 

 hibited as indicating a suitable preserver of the salt as it 

 affords protection against light, air, and breakage. 



As one ounce of Silver Citrate will convert half a pint of 

 sea- water into a drinkable fluid, and a man can keep alive 

 upon it a day, then seven ounces of it will keep him a week, 

 and so on, it may not unreasonably be hoped, in proportion. 



It is proposed to pack the Silver Citrate in hermetically 

 sealed rubber covered bottles or tubes, to be inserted under 

 the canisters or thwarts of the life-boats in ocean going 

 vessels, and this can be done at a simple interest on the 

 first outlay, without any loss by depreciation, as it will 

 always be worth its cost, and be invaluable in case of need.
