1 8 Fowler, Chemical Action of Tropical Sunlight. 

 The following table summarises his results. 



The above results show clearly the much less 

 percentage loss which occurs with increased concentration 

 of the solution. Major Clemesha further showed that 

 little or no loss occurred in the dark or at the temperature 

 of boiling water. 



Professor Delepine informs the writer that he has also 

 noticed the deteriorating effect of sunlight on solutions of 

 chloride of lime in this country and the variation of the 

 effect with concentration. 



The importance of these results in connection with 

 sterilisation or disinfection by chloride of lime is obvious.
