The omission of the study of Natural Science from the course of instruction 
generally followed in this country, appears a neglect of one of the most important 
means of intellectual discipline and moral improvement which the Almighty has 
placed within our reach. This study, rightly pursued, has for its object to enable 
us to read with understanding in that bright volume of Creation, the pages of which 
are daily and hourly unrolled before us. As a means of Intellectual discipline, of 
furnishing a healthy occupation to the thoughts, and worthy objects for rational 
relaxation, the study of Natural Science is second to none; and at a time when 
Science is constantly adding new and important improvements to those Arts which 
minister so largely to our comforts and enjoyments, the practical benefit of a 
general acquaintance with its principles is sufficiently evident. But the more 
exalted tendency of this study, is to cultivate habits of accurate and discriminating 
observation, of cautious reasoning, and sound judgment, together with a sincere 
and earnest love of truth. 
In accordance with these views, the Publishers have determined upon repro¬ 
ducing Dr. Carpenter’s series of Treatises upon the principal departments of 
Natural Science, in such a form, and at such a price as shall place them within the 
reach of all classes. These treatises are all founded upon such knowledge as 
every person of ordinary capacity possesses; the plan of the Works being, that 
the attention of the reader should be directed in the first instance to phenomena 
of constant occurrence around him; and it is hoped that by a judicious mode of 
treating the subject, principles may be developed in such a manner as to render 
them fully comprehensible, and their more extended application clearly marked out. 
Each of the treatises will be complete in itself, but they will all form part of 
one general plan, so that a proper connection and harmony will be entertained 
throughout. In every department care will be taken to give the latest and most 
correct views, and to embody as many facts of striking interest as may be possible, 
so as to furnish entertainment as well as instruction. 
The Part for February is now ready.
