SUPPLEMENT 685 



(8) All privies must be so arranged that the vessels used for the 

 reception of the excreta must not leak, must be protected by a cover, 

 and easily transportable. The emptying of these vessels must be 

 carried out in specially constructed impenetrable pits. 



(9) Defaecation in any other place than a privy is forbidden (alike 

 for miners and brick-makers). 



(10) The manure of horses used in the mines is to be regularly 

 removed ; possibly infection takes place in this way also. [This is 

 impossible.], w! VV. S.] 



How far it is possible to disinfect a mine already severely infected 

 is a matter of question ; Tenholt, 1 Goldmann, 2 and Dieminger a 

 recommend washing out with freshly prepared lime water with the 

 addition of caustic soda ; Calmette 4 and Manouriez 5 spraying with 

 salt water. Theoretically spraying with hot water or steam should be 

 done every now and again for the destruction of the larvae (Looss 6 ), 

 Personal prophylaxis is partially included in the general prophylaxis 

 in so far as it is a case of oral infection, but something more can be 

 done for the individual to avert the danger of cutaneous infection. 

 According to Manson 7 it is advisable in the tropics to cover the 

 naked hands and feet with green Barbados tar, and the tarred parts 

 thickly with flour; Fabre 8 recommends that miners who might come 

 in contact with infected water should anoint the unprotected parts 

 (hands and feet), as then the larvae cannot penetrate the skin ; this last 

 procedure can easily be carried out on account of its simplicity and 

 cheapness. 



Among the usual remedies for the expulsion of ancylostomes 

 thymol certainly comes first, introduced by Bozzolo 9 and since 

 used by many other authors, partly with good and partly with less 

 good results. The day before the beginning of treatment one should 

 endeavour to procure a thorough evacuation of the bowels by means 

 of calomel (Lutz, 10 Griinberger, 11 Smith 12 ) or cascara sagrada (Mann 13 ), 

 only fluid food should be taken the evening before, and on the day 

 of treatment thymol is given in a quantity of 6, 8, 10 or 15 grin., in 

 single doses of 2 grin, with one or two hours' interval, and some hours 

 after an aperient. As a rule, one day of this treatment is not enough
