pathic predisposition. An hereditary association has also 

 been observed between the insipid and mellitic variety. 

 Thus Trousseau, Reith, and Seegen report cases in which 

 the grandfather had the mellitic and the granddaughter the 

 insipid form ; a father and son had the mellitic and a 

 daughter the insipid form, and a son had diabetes mellitus 

 whose father had suffered from diabetes insipidus. The 

 most remarkable instance of hereditary predisposition is that 

 recorded by Lacombe, in which, out of one family a mother, 

 three sons, and a daughter were attacked by the insipid form 

 of diabetes, besides the brother of the mother and his 

 children. Other interesting and less startling cases are 

 reported by Lancereaux, Deebray, Reith, Desgranges, and 

 Addinel Hewson. 



Having thus glanced rapidly at the principal general 

 disorders of nutrition, it will be seen that heredity has a large 

 share in their production ; and although in some instances 

 the testimony recorded may be less satisfactory than in 

 others, yet I firmly believe that in the future, and probably 

 before long, increased experience will not only attest the 

 views I have enunciated, but will throw the light of science 

 over that which may now appear be be vague and 

 hypothetical. 



Acute Infectious Diseases. These are now generally classi- 

 fied as follows viz., I. Contagious: including measles, 

 scarlet fever, variola, vaccinia, typhus, diphtheria, glanders,
