ANALYSIS OF CELERY, (^Jipium Graveohns.) 



By J. H. Salisbury, M. D. 



We have in this case an interesting and remarkable instance of 

 the influence of cultivation upon the size, tenderness and flavor 

 of a plant. Celery in its wild state- is rank, coarse, tough, and 

 untit to eat, but when properly cultivated is sweet, crisp, juicy, 

 and of a most agreeable flavor, and is then highly esteemed as a 

 salad and as a seasoning in soups. 



The sample of the celery analysed was large, succulent, crisp, 

 and finely flavored. It was furnished by Dr. Herman Wendell, of 

 Albany. Its average height 3 feet ; diameter of stalks at base 3 

 inches ; average weight of each plant 10 ounces.
