Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

The sense whose object of perception is form, the distinctive characteristic of fire, is the sense of sight. The sense whose object of perception is taste, the distinctive characteristic of water, is known as the sense of taste. Finally, the sense whose object of perception is odor, the distinctive characteristic of earth, is called the sense of smell.
