been given to it. I believe it to be of much greater importance 

 than the examination of the nasal mucus. The authors lay no 

 stress on the fact that to insure success blood specimens should 

 be taken during the febrile paroxysm. 



During 1915 I took, or had taken, smears from 1,021 known 

 lepers resident at the Culion Leper Colony and at San Lazaro 

 Hospital, Manila, vv^ith results as shown in Tables I to III.

It will be readily seen from the above tables that in the 

 anaesthetic cases where reliable findings in the nasal mucus 

 would be of decided value only 12.9 per cent gave positive results, 

 while 46 and 52 per cent of the mixed nodular cases gave positive 

 findings. The conclusion may be safely drawn that examina- 

 tion of the nasal mucus is of no value as a routine measure.
