the quantity of Ice to be equal to that laft obtained, and formed 

 in the fame manner. 



" January the 21ft in the morning, the Thermometer pointed 

 to twenty-eight. The thin cruft of ice, obferved on the preceding 

 night, did not appear to be encreafed or diminifhed in the veflel 

 marked A. The laminae of this ice adhered fo weakly, that the 

 whole cruft could not be raifed without breaking. This ice, 

 bruifed and well warned, duTolved to near half a pint of water, 

 brackifh to the tafte. And the fame day, in the morning, the 

 ice in B was removed, bruifed, and wafhed; it melted to a pint

" From the 26th of January at fun-fet, to the 27th at eleven 

 o'clock in the morning, the mercury in the Thermometer flood, 

 at the ufual hours of obfervation, between twenty and eighteen. 

 The water remaining after the foregoing congelations in B was 

 frozen fo far, that only half a pint remained fluid. The ice, 

 bruilhed, wafhed, and diflblved, tailed a little brackifli, and mea- 

 fured one pint and a half. 



" On the 28th of January the mercury flood in the morning 

 and until four o'clock in the afternoon between twenty-two 

 and nineteen, and before eleven o'clock at night it funk to feven-

 tempting to take it out. I therefore fuffered it to remain in the 

 liquor until the morning.
