shade, te illustrate the importance of scientific botani- 

 cal names. The Atropa, Circaea, and Solanum, in 

 English, are all called Nightshades, but which ob- 

 viously have very different characters, and are distinct 

 genera. In like manner we have a common Nettle 

 and a dead Nettle, ground Ivy and common Ivy, 

 different kinds of Thistles and Docks; which are not at 

 all allied in nature, and have only obtained their 

 names from vague resemblance or fanciful associations. 

 Urtica and Lamium, Glicoma and Hedera, Rumex 

 and Arctium, Carduus and Sonchus, &c. at once fix 

 the mind, by giving precise and distinct ideas : hence 

 the importance of technical language, so often un- 

 justly depreciated. A familiar idiom is too frequently 

 misty and confused; without clearness there is al- 

 ways danger that the truth is misunderstood; and the 

 value of truth, in all its possible bearings, in every 

 pursuit and investigation, cannot be too scrupulously 

 attended to; for every thing depends upon it, as 

 well in the physical as in the moral world.
