the nutritive operations, and eventually to irreparable 

 structural alteration in the tissues in which they 

 ramify. A number of fatal diseases originate in 

 changes in the vessels, and in many cases it is almost 

 certain that the change in the wall of the vessel is 

 indirectly due to an altered state of the blood, which 

 may have been caused by injudicious living as regards 

 the quantity and quality of solids or liquids swal- 

 lowed.
