diffi as noted in the relative bility of 



( !n oles and Easl Indians: the pen of 



infecl ion in -• lie I Ire iles was 32 - 7 1 . while 



that in the case of the East Indians was 85 78 I' might 



in probable .-it first thai this diffi i as due 



to difference in habits, but since both races live under

In comparing the San Fernando figure's with those 



given by l>v. Marshall for Antigua, onlj the Creole 



ires can be taken in i hi of the formi r as i here 



. i ipulation in Am igua. According 



Dr. Marshall, in some districts, my, a- .")ii percent, of 



adult populal ion and 10 to -7 per ci nt. of the 



childn ii are infected. These percentagi s an high and 



ii lated with th< hargicand Lazy characters 



.is i.f these districts. In the < lenl 



Plain il-- i, the percentage of infection is 



ii 191. lii-- pointed out, however, that 



heavier rain fall and soil of this district render 



more likely to thrive than inth ms areas 



soil and rainfall are lighter. This condi- 



ii of extreme prevalence of 1 1 1 ■ I in the drier 



district more or less unfavourable for it naturally, 



■ m- in point forcibly to the chronic lassitude that 



must prevail amongst the inhabitants. 



A.s regards the eradication of Ankylostomia- 

 recommended that efforts should be 



ixamine and treat, where infected, every 



iid child in the villages until they 



pronounced free from infection. It is imp 



tant that latrines of a suitable pattern should be 



in each village, and that the people should 



be comp lied to make use of them. Water sources 



uld be carefullj pr I I from contamination. 



Finally, provision should be made to prevent the 



entn or n entrj of infected persons from abroad. 



Anyone failing to produci a certificate of health should 



be quarantined until certified to be free from anky- 



mir ova.

Even in I'. mama, on the Canal Zone, Ankylos- 

 tomiasis is still very common, or was in 1912, when 

 I >r. D. Thomson visited the /.one on the Malaria 



Expediti I* that yeai i i | NevertheL ss the di 



is combated by the establishment of a ver) thorough 

 latrine system along the line of the Canal. The 

 irj Inspectors look after the latrines in their 

 respective districts. The latrines are fly-proof, and 

 their position is frequently changed. Patients coming 

 into the hospitals and dispensaries are constantly 

 examined for ankylostome ova, and tin \ are e 

 a thorough course of santonine treatment if these 



are found. 



All that we- have said in the preceding para 

 graphs puts emphasis on the fact that Ankylo 

 is a w idely prevalenl d disease seriously 



affecting tropical labour. It is therefore in the 



rest of the planter to i perate in enforcing 



measures tor ils eradication. The rays in which this 

 can be done have been outlined above. To the measures 

 sted may be added a ingot - educational cam- 

 paign. More might be done in the elementarj si 

 to make the children realize the importance of living 

 ' i-eordanee with the principles oi hygiene; more 

 might be done on the estates to encourage the 

 observance of such teaching in every-daj life.
