substance used by the writer, chloride of lime, is sprinkled on the surface 
of the water, and it to a great extent distributes itself by sinking through 
the water. The results of the bacteriological tests certainly indicate that 
the substance has a very great purifying power.

The indcor swimming pool is a valuable hygienic factor in our public 
baths and gymnasiums. It makes the bath attractive to many who would 
otherwise look upon bathing as a bore. Anything which will tend to make 
the boys and girls, youths and maideps, men and women bathe more fre- 
quently is desirable. But the swimming pool has its dangers, and most of 
these depend not upon the users of the pools alone, but much more on the 
construction and management of them. Therefore we must look to the 
builders and directors of our baths and gymnasiums for the satisfactory 
hygiene and sanitation of indoor swimming pools.
