 as Bursaria, Kolpoda, Paramecium, Cyclidium and Goni- 

 um. 



" O LoKD, how manifold are thy works ? in wisdom hast 

 thou made them all : the earth is full of thy riches. So is this 

 great and wide sea, wherein are things creeping innumer- 

 able, both small and great beasts. There go the ships : 

 there is that leviathan whom thou hast made to play 

 therein. These wait all upon thee : that thou mayest 

 give them their meat in due season. That thou givest 

 them they gather : thou openest thine hand, they are fill- 

 ed with good. Thou hidest thy face, they are troubled ; 

 thou takest away their breath, they die, and return to 

 their dust. Thou sendest forth thy spirit, they are crea- 

 ted : and thou renewest the face of the earth."
