San I'RANoisco, July 7tb, 188G. ) 



I took a severe eold upon 

 mv ehest and lungs and did • 

 not give it proper attention; 

 it developed into bronchitis, 

 and in the fall of the same 

 year I ^was threatened -with 

 consumption. Physicians or- 

 dered me to a more congeni- 

 al climate, and I came to San 

 Francisco. Soon after my 

 arrival I commenced taking 

 Scott's Emulsion of Cod Liver 

 Oil with Hypophosphites reg- 

 ularly three times a day. In 

 ten weeks my avoirdupois 

 went from 15S to 180 pounds 

 and over ; the cough mean- 

 time ceased, c. R. bennett.
