Note: / This paper gives results of investigations made on celerey grown in sand cultures and exposed to different degrees of frost. After each treatment water loss was determined by the weighing method. The plants exposed to 30 degree F. were not appreciably affected. These having undergone a frost at 28 degrees F. were somewhat injured but recovered. A temperature of 26 degrees F. killed the outermost peticles but a partial recovery followed. At 24 degrees F. the whole plant was killed and did not recover. A severe frost followign a light frost caused apporximately the same effect as if it had occurred alone. The more severe the frost, the lower was the amount of water loss. In general, during the first day the water los was less than during the seocnd and thrid days and then again decreased.
