from sources similar to that of Broad Street, With the supply of water now furnished 
hy the drinking-fountains such a temporary closing of these surface wells could not 
occasion any serious inconvenience, and might be the means of saving thousands of lives. 
It cannot be too strongly insisted upon that pollution of a nature to spread infec¬ 
tion often really exists without sensibly affecting either the taste or the appearance of 
the water. 
Citrate of Soda in Diabetes.—We learn from the ‘ Lancet ’ of July Tth, that M* 
Guyot-Danecy, basing his practice upon the theory that diabetes arises from imperfect 
combustion of the glucose of the blood, proposes to employ citrate of soda in order to 
supply the alkaline carbonate which is necessary to the progressive chemical change of 
the glucose. He substitutes the citrate for the carbonate, because, he says, it does not 
affect the function of digestion. The salt is given in doses of from 4 to 8 grammes. 
His analyses, he alleges, demonstrate that sugar disappears from the urine after the 
administration of the citrate. Citrate of soda may be mixed with food instead of salt, 
and with it the use of ordinary broadband starchy matters ceases to be objectionable.
