SALICYLIC ACID AND SALICYLATES. 543 



No. A 



There is noticed here for the first time a decided increase in the sul- 

 phur ratio in the preservative period, while the sulphuric-acid and 

 phosphoric-acid ratios remain unchanged. In the after period there 

 is a slight falling off in the sulphur ratio as compared with the pre- 

 servative period, no change in the sulphuric-acid ratio, and a notable 

 increase in the phosphoric-acid ratio. 



No. 9. 



There is a slight diminution in the magnitude of the sulphur and 

 sulphuric-acid ratios in this case and a notable loss in the phosphoric- 

 acid ratio during the preservative period. In the after period the 

 sulphur ratio is increased beyond its original magnitude, the 

 sulphuric-acid ratio is restored to the figure for the fore period, and 

 there is an increase in the magnitude of the phosphoric-acid ratio over 

 the preservative period, but it does not quite reach the magnitude of 

 the fore peribd. 



No. 10. 



There is no change in the sulphur and sulphuric-acid ratios in the 

 preservative period in this case and a slight diminution in the mag- 

 nitude of the phosphoric-acid ratio. In the after period there is a 

 slight loss in the magnitude of the sulphur and sulphuric-acid ratios 

 and a notable increase in the phosphoric-acid ratio. 



No. 11. 



The ratios of sulphur and sulphuric acid are smaller in this case in 

 the preservative period and that of phosphoric acid larger. In the 

 after period there is a still further diminution in the magnitude of the 

 sulphur ratio over the preservative period, no change in that of the 

 sulphuric acid, and a still further slight increase of ratio of the phos- 

 phoric acid. 



No. 12. 



We have here the third instance of an increase in the magnitude of 

 the sulphur, ratio in the preservative period, accompanied with a slight 

 decrease in that of the sulphuric-acid ratio and the phosphoric-acid 

 ratio. In the after period the sulphur ratio is slightly diminished as 

 compared with that of the preservative period, the sulphuric-acid ratio 

 remains unchanged, and tljere is a notable increase in the magnitude 

 of the phosphoric-acid ratio. 



SUMMARY FOR NINE MEN. 



Combining into one expression the nine ratios which are complete 

 and comparable, it is seen that there is a notable diminution in the 

 ratio of sulphur and a slight diminution in the ratio of sulphuric acid
