tirely. When placed in water shallow 

 enough to enable it to keep its head in 

 the air, if desired, and to which a little 

 sea salt had been added to cure the dis-

 absorbed and the creature became cured 

 of the disease. At the time of writing, 

 August, the axolotl is just about to leave 

 the water as a perfect amblystome. This 

 probably means that the disease in some 



if one of these might not come onto land 

 as a creature hitherto unknown to 

 science. Scarceness of living material in 

 England makes this almost impossible, 

 but in the native countries of these crea- 

 tures it should not be difficult. It may 

 be possible ; who knows until he tries ?

 principles on which it acts. It would be 

 very interesting and useful if anyone 

 would experiment on permanently aquat-

"I discharge this jury!" 



A tall, lean member of the twelve then 

 rose. 



"Say, judge, you can't discharge me." 



"Can't discharge you ? Why not ?" 

 thundered the judge. 



"Waal," replied the juryman, pointing 

 to the counsel for the defense, "I was 

 hired by that guy over there !" — Jack
