Researches on the Etiology of Endemic Goitre. 337 
TREATMENT OF GOITRE BY Lactic AcID FERMENTS. 
BEFORE. AFTER. 
Figures illustrating the action of the Bacillus Bulgaricus in the treatment of incipient 
goitre. The figure to the left of the observer represents the case before treatment; that 
to the right the same case after 30 days’ treatment with “soured milk.” Fourteen ounces 
of “soured milk” were consumed daily. Attention is directed to the loss of subcutaneous 
fat as a result of the treatment. This result is common to all successful medicinal treat- 
ments of goitre, whether by iodine, thymol, or lactic acid ferments. 
6. It is very probable that the agent which is responsible for the production 
of goitre is a living organism parasitic in the human intestine. 
7. The disease cannot be communicated to dogs by means of watery 
extracts from the feeces of goitrous individuals. 
The results confirm in detail those which I communicated to the Royal 
Society on November 26, 1908. 
Photographs are given of a case of incipient goitre treated by B. Bulgaricus 
and of the artificial production of goitre by goitre-producing water.
