the withdrawing of so much air as has been mentioned, emitted no froth, and 

 but few bubbles. 



2dly. Tlie fish both at his mouth and gills for a great while discharged such a 

 quantity of bubbles a:s appeared strange, and for about half an hour or more; 

 whenever he rested a while, new bubbles would adhere to many parts of his 

 body (as if they were generated there) especially his fins and tail : so that he 

 would appear almost beset with bubbles, and if, being excited to swim, he was 

 made to shake them off, he would quickly, upon a little rest, be beset with new 

 ones as before. 



3dly. Almost all the while he would gape and move his gills, as before he 

 was included ; though towards the end of the time that I watched, it often 

 happened, that he neither took in, nor emitted any aerial particles that I could 

 perceive. 



4thly. After a while he lay almost constantly with his belly upwards, and yet 

 would, in that posture, swim briskly as before. 



5thly. Nay after a while he seemed to be more lively than at first putting in ; 

 whether by reason, that by discharge of so many bubbles, which by their dis- 

 tension perhaps put him to pain, he found himself relieved, or for some other 

 cause, I examine not. 



Having occasion to go abroad, I returned about an hour and a half after he 

 had been sealed up, and found him almost free from bubbles, and with his belly 

 upwards, and seeming somewhat tumid, but yet lively as before. But an hour 

 and a quarter after that, when rising from dinner I went to look upon him 

 again, he seemed to be motionless and somewhat stiff; yet upon shaking the 

 glass, observing some faint signs of life in him, I opened the receiver under 

 water, to try if that liquor and air would recover him ; and the external water 

 rushing in till it had filled the vacant part of the ball and the greatest part of the 

 stem, the fish sunk to the bottom of it, with a greater appearance than ever of 

 being alive ; in which state, after he had continued some time, I contrived, by 

 the help of the water he swam in, to get him through the pipe into a basin of 

 water, where he gave more manifest signs of life : but yet for some hours lay 

 on one side or other, without being able to swim or lie on his belly, which ap- 

 peared v^ery much shrunk in, as if something during the time of its being sealed 

 •up had been broken in his body, or his belly had been exceedingly distended, 

 beyond restitution to its former tone. 



All the while he continued in the basin of water, though he moved his gills 

 as before he had been sealed up ; yet I could not perceive that he did, even in 

 his new water, emit as formerly any bubbles, though two or three times I held 

 him by the tail in the air, and put him into the water again ; where at length
