The air was compressed tncclianically to ^ig, without 

 much deviation from Hooke's law ; by freezing it was re- 

 duced to ^of its bulk. •

According to Lavoisier l cubic inch Fr. of air weighs 48 

 grains. A. P. V77*. 364. According to Fouchy a, cubic 

 foot weighs 10 gros. A. P. 17 80. 3. A hundred English 

 wine gallons weigh a pound avoirdupois. 



Roy thinks that there are some exceptions to the law of 

 Boyle and Mariotte. Ph.tr. 1777. Others attribute these 

 irregularities to the presence of water.

Bodies floating on the surface of water in an eddy are 

 impelled either towards the centre or towards the circum- 

 ference, according to circumstances ; they are not made to 

 approachthe centre on accountof their levity, since they only 

 displace as much water as is equal to their own weight, but 

 probably because the resistance of the air causes them to 

 move more slowly, and to have less centrifugal force than 

 the water. When they move towards the circumference, 

 it is probably because of the greater retardation of the water 

 from the friction of the vessel. Y.
