SULPHUROUS ACID AND SULPHITES. 888 



the preservative period but the number is restored in the after period 

 and even increased beyond the number in the fore period. There is 

 a very marked decrease in the number of white corpuscles, and this 

 decrease continues in the after period. The color index rises in the 

 preservative period, falling to a smaller figure in the after period than 

 in the fore period. 



In the case of No. 2 there is a slight increase in the hemoglobin, 

 both in the preservative and in the after period. There is a decrease 

 in the number of red corpuscles in the blood in the preservative period 

 and an increase in the after period, though the number is not restored 

 to that of the fore period. The white corpuscles in this case increase 

 during the preservative period and still further increase in the after 

 period. The entire data of No. 2 show that the administration of 

 sulphurous acid in this case had no marked tendency to diminish 

 the number of blood corpuscles, having decreased only slightly the 

 number of red corpuscles and increased to a very marked extent the 

 number of white corpuscles. Perhaps a better form of expression in 

 this case is that the administration of the sulphurous acid was attended 

 with a slight decrease in the number of red corpuscles and a marked 

 increase in the number of white corpuscles. The color index increases 

 in the preservative period and remains practically the same in the 

 after period. 



No. 3 shows a decrease in the number of red corpuscles during the 

 preservative period and a notable increase in the corpuscles in the 

 after period, the number rising to a higher figure than in the fore 

 period. There is a slight increase in the number of white corpuscles 

 during the preservative period and a marked increase during the after 

 period. The hemoglobin data for No. 3 show an increase in the pre- 

 servative period, which is maintained in the after period. The color 

 index increases during the preservative period, falling in the after 

 period to an amount less than in the fore period. 



No. 4 shows a very marked decrease in the number of red corpuscles 

 during the preservative period and a still further decrease in the 

 after period. There is also a very marked decrease in the number of 

 white corpuscles in both periods. Here the data show that the admin- 

 istration of the sulphurous acid was attended by a marked decrease 

 of both the red and the white corpuscles. 



The data for No. 5 show a very marked decrease in the number of 

 red corpuscles during the preservative period and a slight recovery, 

 that is, a slight increase in the number of red corpuscles in the after 

 period over the preservative period, but not a complete restoration to 

 the number present in the fore period. There is also a marked 

 diminution in the number of white corpuscles during the preservative
