then a half moon; 

 three quarters full ; 

 and, lastly, the moon 

 attaining a position 

 opposite to the sun, 

 its whole illumined 

 disk is presented to 

 the earth, when it is 

 called a FULL MOON; 

 Advancing onwards 

 hi its orbit, its illu- 

 mined surface is gra- 

 dually inverted from 

 the earth, until it 

 entirely disappears, 

 and the Moon hacomes 

 invisible, as at first. 



ECLIPSE OF THE SUN 



Eclipse of the Sun. 



An eclipse of the sun 

 is caused by the 

 moon so coming be- 

 tween the sun and 

 earth, as to prevent 

 the rays of the former 

 from falling on cer- 

 tain portions of the 

 latter. This pheno- 

 menon can only hap- 

 pen at the time of 

 new moon, and when 

 she is at, or near, 

 one of her nodes.

side of the globe is 

 caused by the moon 

 attracting the solid 

 body of the earth 

 away from the waters 

 on that side, causing 

 them to be elevated 

 into a similar swell. 

 Thus we have two 

 daily tides. SPUING 

 TIDES occur from the 

 combined influence of 

 the sun and moon 

 when they are in con- 

 junction, causing the 

 tides to be more ele- 

 vated.
