The six remaining sharks survived the treatment to this date and later, and 
were used for infection experiments. When examined they gave results as follows:

Table 3 shows less satisfactory results than the foregoing, the 
net results being as follows: without parasites 11, found dead 
and so decomposed that no data were obtained 3; still infected 6. 
If the survivors alone are considered the results are not nearly 
so good, for out of ten surviving specimens (Nos. 8, 10, 11, 12, 
13, 14, 17, 18, 19, and 20) we have only four (Nos. 8, 10, 11, and 
17) which are entirely free of cestodes, while there are six (Nos. 
12, 13, 14, 18, 19, and 20) which are still infected. Of these six, 
Nos. 12, 18 and 18 have but a single parasite, so the chances are 
that some parasites have been eliminated, but Nos. 14, 19 and 20
