San Fbancisco, July 7th, 1886. ) 



I took a severe eold upon 

 my 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 ^vith 

 consumption. Physicians or- 

 dered me to a more congeni- 

 al climate, and I came to San 

 Francisco. Soon alter 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 155 to ISO pounds 

 and over ; the cough miean- 

 time ceased, c. R. Bennett.
