360 APPENDIX. 



the scale of creation, to the circumstances in 

 which they are placed ; so many contrivances, 

 exhibiting the deepest intellect, taking the most 

 comprehensive surveys of every possible contin- 

 gency, and rearing a structure calculated to stand 

 against every pressure upon it, we must feel 

 convinced that the attention of the Creator is 

 directed to every individual in existence, whether 

 great or small, high or low, spiritual or material. 

 To every thing that he created he gave a law, 

 the law of its nature; a law emanating from 

 Him, enforced by the physical powers acting 

 upon certain structures, and producing certain 

 necessary effects under His constant superinten- 

 dence, direction, and action, on and by those 

 powers. 



The intestinal worms, as well as some other 

 parasitic animals, are many of them so remark- 

 able for the situation in which we discover them, 

 that their transport to the spot where they are to 

 exercise their function seems almost miraculous. 

 How a mite should find its way into the human 

 brain seems past our conjecture. We cannot 

 clearly ascertain by what means the eye- worms 

 are conducted to their assigned station, nor how 

 the various species of tape-worm invariably 

 select each its proper pabulum : the same holds 

 good with regard to the cyst-worms, 1 or hyda- 



1 Cysticercus.
