Inspection of Table 1 will show that the worm counts in cases 

 6 and 11 were very high. So far as we have knowledge, they 

 are the highest that ever have been recorded in the Philippines. 

 It is probable that the yield from case 9 was as high as, if not 

 higher than, either of these, for great masses of worms were 

 seen when the work of washing the stool was in progress. 

 Unfortunately, however, a 15 per cent solution of sodium hy- 

 droxide was employed to break down a heavy deposit of thick, 

 tenacious mucus, and the worms shrank and disappeared through 

 the meshes of the screen as if by magic, being lost to view in a 

 few seconds. The subject was a man, 68 years of age, who 

 presented a very extreme picture of hookworm disease. 



Cases 3, 4, and 8 present the apparently anomalous picture 

 of a pronounced ansemia coupled with a relatively low worm 

 count. This can be explained, so far as cases 4 and 8 are con- 

 cerned, by the large proportion of ancylostomes present, amount- 

 ing in case 4 to 19 per cent of the total number, and in case 8
