SULPHUROUS ACID AND SULPHITES. 879 



In the case of No. 7 the data are fragmentary, but permit of a com- 

 parison between the fore and preservative periods. There is a de- 

 crease m the number of red corpuscles in the preservative period and 

 an increase in the number of white corpuscles, the percentage of color- 

 ing matter remaining the same. The color index shows an increase in 

 the pre ervative period and no data are available for the after period. 



In the case of No. 8 there is a very marked decrease in the number 

 of red corpuscles during the preservative period and this decrease is 

 still further continued in the after period. There is a very large 

 decrease in the number of white corpuscles in the preservative period 

 which is only partially restored in the after period. There is a slight 

 decrease in the preservative period in the percentage of coloring mat- 

 ter and this is continued in a somewhat more marked way in the after 

 period. The color index is increased in the preservative period and 

 the increase is maintained to a greater extent in the after period. 



In the case of No. 9 there is an increase in the number of red cor- 

 puscles and an enormous increase in the number of white corpuscles 

 during the preservative period. At the same time there is a slight 

 decrease in the percentage of coloring matter. In the after period 

 a tendency is manifested to restore the conditions which obtain in 

 the fore period. The color index is decreased during the preservative 

 period and rises again in the after period to practically the same fig- 

 ure as in the fore period. 



The data in the case of No. 10 show a marked decrease in the num- 

 ber of red and white corpuscles during the preservative period and 

 a slight decrease in the percentage of coloring matter. In the after 

 period there is a restoration of the numbers of white and red cor- 

 puscles almost to the initial number in the fore period, but the per- 

 centage of coloring matter remains the same as in the preservative 

 period. The color index is increased during the preservative period, 

 returning to practically the same figure in the after period as in the 

 fore period. 



In the case of No. 11 there is a small decrease in the number of 

 red corpuscles and a large increase in the number of white corpuscles 

 during the preservative period. The percentage of coloring matter 

 remains the same. There is a large increase in the number of red 

 corpuscles in the after period, but the number of white corpuscles 

 is smaller. The percentage of coloring matter remains almost the 

 same in the three periods. The color index is increased during the 

 preservative period, falling in the after period to a figure below that 

 of the fore period. 



In the case of No. 12 there is a slight decrease in the number of 

 red corpuscles and an increase in the number of white corpuscles 

 during the preservative period, the percentage of coloring matter
