A MANUAL 



of Natural History, even to a slight extent, we must 

 drive a few "hard words" into our heads. It will be 

 ver}^ good for the memory; and will present very 

 little difficulty, even to those who are not learned in 

 the Latin and Greek tongues, if they take two simple 

 precautions : — First, remember that a long " hard 

 word" means something; Secondly, get some one to 

 translate it or tell you what it means : you will then 

 connect an idea with it, and this will aid your 

 memory, and sometimes furnish you with a useful 

 fact. So you will learn things and not ntere icords. 

 For instance, take the word " Kadiate ;" at first you 

 think there is no reason why it should not be 

 " Chroton-hoton-thologos," or any other piece of 

 nonsense, but once understand that it means 

 "rayed," and you will learn a fact about many 

 animals of the class, and will recollect the word 

 itself without difficult}''. 



Next, as to the distinction between a coral and an 

 anemone. I paused at the end of the Helianthoids, 

 or "sunflower-shaped" zoophytes, because, after so 

 many long words, we seemed to require a rest, and 

 this was the most natural halting-place. 



Now we will proceed, and separate our friend 

 from his numerous relations. Having settled that 

 the animal in question is a Ilelianthoid, we ask two 

 questions : — 



Is he partly covered with a hard shell or coating 

 of lime, firmly fixed to the rock ?
