ALLEGED PRODUCTION OF BARLOW'S DISEASE 223 



found to be usually within fourteen months, except where the 

 infant has been very far from the normal at the time of its first 

 attendance or has suffered subsequently from measles, whooping- 

 cough or other bacterial infection ; in not a few cases the child 

 has walked before the end of the first year, and in one case at nine 

 months. I have also followed up as many as possible to the ages 

 of three, four, and five years, and am personally convinced that 

 there is no more risk of rickets with this diet than with a good 

 quality raw cow's milk.' He also states that it is possible to cure 

 rickets by changing a previously-given diet to a dried-milk diet. 



It is a well-known fact that the incidence of rickets varies con- 

 siderably in different countries and in different districts, and it 

 is probable that although feeding cannot be entirely excluded, 

 other factors are concerned in the production of rickets. Many 

 French physicians believe that rickets can be induced as a result 

 of over-feeding, and this view is also held by Pritchard. 



Findlay, who has carried out experimental work upon the 

 production of rickets, believes that bad sanitation and absence of 

 proper ventilation must be regarded as largely responsible for the 

 production of this disease. 



It is impossible to discuss the question of rickets further in this 

 work.
