Ankylostomiasis hi Grenada 
(e) Proper drainage of the estates is also an important measure; 
for it is in the dank, warm soil under the shelter of the trees that the 
ideal conditions for the development of the larvae are obtained. 
(/) The institution of dispensaries for the free treatment of this 
disease and the free distribution of drugs is also an essential measure 
for eradicating the parasite from the Colony. 
The best drug, in my opinion, for distribution in this way is beta 
naphthol in the form either of pills or in mucilage. In cases where 
the estate was situated too far from one of the dispensaries, a free 
supply of the pills, with instructions as to their administration, could be 
issued to the overseer or manager for the use of the labourers. I cannot 
too strongly emphasise the responsibility of the estate owners in this 
matter; since, at present, the whole of the legislation of the Colony is 
in their hands. I am confident that the adoption of these or similar 
measures could entirely rid the island of the disease; and at the same 
time lessen the mortality of the island to at least one half its present 
proportions. 
Even from an economic standpoint the cost of these measures would 
be saved many times over; for the loss of time from sickness, the cost 
of maintenance and treatment in the Government Hospitals, and the 
natural shortage of labour and increase of wages resulting from the 
disease, would be avoided. 
The methods of administering the various vermifuges mentioned in 
this paper were as follows ; 
(a) Thymol. The patient who was to receive this drug was put on 
to a milk diet for twenty-four hours previous to administration. The 
bowels were opened at 6.0 p.m. of that day with a saline aperient. At 
6.0 a.m., the following morning, thymol gr. 20, in cachet form, was 
administered and at 8.0 a.m. the same dose repeated. At 12.0 noon 
a saline aperient was again given and the resulting motions saved and 
washed. 
{h) Eucalyptus Oil, Castor Oil and Chloroform. As in the thymol 
method the patient to receive this drug was put on to a milk diet the 
day previously and was similarly given a saline aperient the night 
previous to administration. At 6.0 a.m. an emulsion containing 01. 
eucalypti m. 15, chloroformi m. 20 and 01. ricini dr. 5 was given; this 
was repeated at 7.0 a.m. The resulting motions were collected and 
washed, and examined for parasites.
