160 LECTURE XII. 



answers the double purpose of telescope and 

 microscope, enabling her to see the very small- 

 est seed on the ground, and to discover birds 

 of prey at a long distance. Some animals have 

 both wings and feet, and some are without 

 either, such as fish, which can move about with 

 great rapidity, and have a bladder, by means 

 of which they can rise and fall in the water 

 at will. The formation of birds also shows a 

 wonderful contrivance; their bodies, small and 

 sharp before (like one of your boats), increase 

 gradually. They can thus cut the air, as boats 

 do the water. The feathers are all arranged 

 with great skill, arid are laid over one another 

 in regular order. The wings are placed in the 

 proper place, so as to balance the body exactly. 

 The tail serves as a rudder to direct the flight, 

 and helps the bird to ascend or descend in the 

 air. Such are a few of the arrangements of a 

 Divine Providence in the works of creation, and 

 they ought to excite your wonder as well as 

 your gratitude. Well may we exclaim with 

 the Royal Psalmist, "O Lord, how manifold 

 are Thy works! In wisdom hast Thou made 

 them all. The earth is full of Thy riches."
