DISEASES OF THE GENERATIVE SYSTEM 



The great danger of this period is diarrhoea or dysentery from 

 infections with am^Debse or bacilh. 



AH the diseases which attack adults in the tropics may affect the 

 child after birth, and the special features which they show have 

 already been recorded, as well as the treatment, in the chapters 

 on the various diseases, and need not be repeated; but the danger 

 of the child being infected with tuberculosis is very great, especially 

 in the slums of large towns. 



Dosage of Drugs. — As we have often been asked for Ihe dosage 

 of drugs in young children, we give the following rules: — Several 

 drugs, but especially opium, require to be given with caution, as 

 children are especially susceptible to them; but excluding these, the 

 best^ method so far published for the determination of dosage by 

 age is Cowling's rule with Brunton's modification. 



In brief, it is to take the full adult dose and divide it by a factor 

 obtained by placing the child's age at its next birthday over twenty- 

 four if the ordinary British weights and measures are used, and 

 over twenty-five if the metric system be employed. For example, 

 suppose that the full adult dose is 6 grains and the child's age next 

 birthday is four years, then the factor is (^"•^•. i) and the dose 

 is I grain.
