( b ) Buchu, Turpentine, Hexamine and Cystopurin, to accelerate the 
escape of eggs and to counteract the bacilluria. 
(c) Adrenalin in severe cases of haematuria. 
(d) Tr. Hyoscyamus and Sodium salicylate for the renal colic and 
injections of morphia where required. 
(e) Iron and tonics for the anaemia. 
It should be borne in mind that the disease is intractable and in many 
cases resists all forms of treatment; whilst it is the opinion of many with a 
large experience of the disease that where complications do not arise, the 
disease may be left to die out of itself without treatment of any kind. My 
own feeling is that, so long as there is haematuria and flakes of mucous mem¬ 
brane in a cloudy urine, the patient is well advised to persist in taking some 
form of urinary antiseptic; but, until we are in possession of a drug which is 
known to destroy the parasites, it is unwise to persist in the use of uncertain 
remedies. 
CONCLUSIONS. 
1. That Billiarzia cercariae, similar to those which have been demonstrated 
to cause Bilharziasis in Egypt, occur in Natal in specimens of Physopsis 
africana. 
2. That specimens of Physopsis africana abound in infected localities, 
and that a large proportion of these are infected with Bilharzia cercariae. 
3. That specimens of Physopsis africana, when exposed to infection from 
the urine of Billiarzia patients, increase in the number of infected forms. 
4. That experimental infection of animals has been unsuccessful and, as 
far as is known, animals in Natal are not susceptible to the disease. 
5. That it is rare to come across a person whose life has been shortened 
or whose death has been caused from Bilharziasis in Natal. 
6. That, until some specific is known, palliative measures are the only 
ones that can be recommended in the treatment of the disease. 
7. That municipalities would be well advised to follow the example of 
Durban in filtering their water-supply, or, where this is impracticable, the water 
should be strained through such copper ribbons as are in use at Pietermaritz¬ 
burg which preclude the possibility of infected snails entering the reservoir 
from which the town supply of water is derived. 
8. That, in infected areas, river bathing should be forbidden and suitable 
swimming-baths provided.
