SALICYLIC ACID AND SALICYLATES. 559 



total sulphates both in the preservative and after periods. There is 

 also a decrease in the ethereal sulphur in the preservative period and 

 this decrease is continued in the after period. The percentage of inor- 

 ganic sulphates is diminished in the preservative period and still 

 further diminished in the after period. 



No. 3. 



The neutral sulphur is increased in the preservative period and very 

 notably increased in the after period, while the percentage of total 

 sulphates decreases in both periods. The ethereal sulphur is very 

 low in this case and slightly higher in the preservative period than 

 in either the fore or after period. The percentage of inorganic sul- 

 phur decreases slightl} 7 in the preservative period and very notably in 

 the after period: 



No. 4; 



There is a slight increase in the neutral sulphur in the preservative 

 period and a notable increase therein in the after period, with corre- 

 sponding inverse changes in the percentage of sulphur as sulphates. 

 The percentage of ethereal sulphates is increased in the preservative 

 period, with a slight loss in the after period. The inorganic sulphates 

 show a loss in the preservative period and a still further slight loss in 

 the after period. 



No. 5. 



There is a notable increase in this case of the neutral sulphur in the 

 preservative period and a still further slight increase in the after 

 period, with corresponding inverse changes in the total sulphur as 

 sulphates. The percentage of ethereal sulphates is slightly diminished 

 in the preservative period and still further diminished in the after 

 period. The percentage of inorganic sulphates is notably diminished 

 in the preservative period and again slightly decreased in the after 

 period. 



No. 6. 



The percentage of neutral sulphur is slightly diminished in the pre- 

 servative period, but very notably increased in the after period, with 

 correspending inverse changes in the percentage of total sulphates 

 present. The percentage of ethereal sulphates remains practically 

 unchanged throughout the three periods. There is a slight increase in 

 the percentage of inorgani^ sulphates in the preservative period and a 

 notable decrease therein in the after period. 



No. 7. 



This case shows an extraordinary increase in the neutral sulphur in 

 the preservative period. This increase is nearly all lost in the after 

 period, where the percentage is only slightly greater than the fore
