3. Hybrid names, partly Greek and partly Latin, or com- 

 pounds of any two diverse languages, such as Dendrofalco, 

 Gymnocorvus, Arboroplulus, Flavigaster, Monoculus, &c. 



While strenuously advocating correct terminology, derived 

 from classical sources, we should not attempt to discard from 

 scientific use many terms which have become well established. 

 Such are some which may be styled Onomatopoeic, as Pee-weet, 

 Wet-my-Foot, Humming bird, &c, which have become household 

 words. 



The Lecturer next proceeded to apply such general principles, 

 by adducing some practical rules for the formation and employment 

 of scientific terms, and, in so doin^, strongly urged the necessity 

 of at least an elementary knowledge of the classical languages 

 forming a part of all popular education. This is by no means 

 difficult of attainment, and should be placed within the reach 

 of all. 



By means of such an acquirement, scientific language, other- 

 wise often nearly unintelligible and uninteresting, becomes a 

 vehicle of instruction and delight. Examples of this may be 

 found in such teruis as phanerogamic and cryptogamic, in the 

 vegetable kingdom; or malacopterygii and acantliopterygii, in the 

 animal. To any one, even moderately acquainted with the 

 languages whence such terms are borrowed, they ave full of 

 instruction, and readily explain themselves. A great many 

 other similar terms were adduced as examples. 



Correct classification in alliance with correct terminology is 

 an absolute necessity, for the purposes of adequate scientific 

 knowledge. A comparison of the divisions of manmalia, by 

 Cuvier and Owen, respectively, was adduced to illustrate the 

 incorrect nomenclature adopted by the latter, whose leading 

 divisions, founded on the convolutions of tbe brain, are nearly 

 all misnamed. These are the well-known arcliencephala, gyren- 

 cepliala, lissencephala, and JycucepJiala, which present an example 

 of singularly faulty nomenclature, founded, too, on an equally 

 lax division. 



An illustration of an equally correct division and nomen- 

 clature is to be found in Harvey's concise and beautiful division 

 of Algse in the Phycologia Britannica, where the three sub- 

 classes of Melanospermeoe, Uhodospermeoe, and Chlorospermece,
