gence, she gives them other things. For example : there is a 

 marine worm, the Eunice sanguinea, which is sometimes to be 

 found on our coast, and attains the length of about two and a 

 half feet. This creature, says Dr. Hartwig, consists of about 

 300 rings. A brain and three hundred ganglia, from which 

 about 3000 nervous branches proceed, regulate the movements, 

 sensations, and vegetative functions of a eunice; 280 stomachs 

 digest its food; 550 branchiae refresh its blood; 600 hearts 

 distribute this vital fluid throughout the whole body; and 

 30,000 muscles obey the will of the worm, and execute its 

 snake-like movements. Why, this seems to suggest a super- 

 fluity of force equal to that found in attendance upon royalty !

Profitable Panic-Mongering. 



Wolves prey upon the moose or red deer, but are unable to 

 catch them by speed of foot. In consequence, a number of 

 wolves will combine together to encompass a herd of deer on 

 large plains bounded by steep cliffs. While the deer are grazing, 

 the wolves will form a crescent round them, and creep stealthily 

 forward so as to alarm them as little as possible at first! ; but 

 when they see that they have fairly hemmed them in, and cut 

 off their retreat, they begin to move more quickly, and at last 

 rushing on with loud yells they terrify the deer, and urge them 

 to flee towards the precipice, as if they knew that when the 

 herd is once put to its speed, some of them must be driven over 

 the cliffs, the hindermost forcing on those in front. When 

 several have thus been precipitated, the wolves go down at their 

 leisure and feast upon their mangled bodies. B. 



Progress Sometimes only Seeming, not Heal. 



The currents of the sea are found to run in all directions, 

 east, west, north, south, being formed by various causes the 

 prominence of the shores, the narrowness of the straits, the 

 variations of the wind, and the inequalities at the bottom. 

 These currents are of the most material consequence to the 

 mariner, without a knowledge of which he could never succeed. 

 It often happens that when a ship gets unknowingly into one
