18 INTRODUCTORY REMARKS. 



toms of pages, so that they will be in part composed of the 

 capitalized words of corresponding paragraphs, thus making the 

 questions strikingly topical, and not liable to objections. 



These improved methods, in connection with the admirably 

 illustrative cuts furnished by the publishers, will, it is hoped and 

 believed, assist in habituating students to correctly exercise and 

 develop their thinking powers, and enable them to become 

 more pleasantly, rapidly, and completely acquainted with the 

 laws of Hygiene than previous opportunities have allowed. 



The work is addressed to those desirous of self-improvement, 

 and willing to take the pains necessary for it ; who value them- 

 selves as having minds as well as bodies, the former of which 

 can be as much improved by mental as the latter by physical 

 gymnastics ; who think that man in his rich endowment of 

 immortality is ennobled above all comparison with earthly 

 distinctions, 'and worthy of his own highest respect and care; 

 who desire to learn, therefore, not merely to recite a lesson, but 

 to obtain knowledge, and, feeling the value of this acquisition, are 

 willing to invest the necessary labor : also to teachers who 

 esteem the " laborer worthy of his hire," and demand it, yet 

 enjoy an additional rich reward in doing that which will consti- 

 tute the germs of exalted habits in future generations through 

 widespread communities, and are ever ready to impart know- 

 ledge to those desirous of learning the laws of Hygiene. 



In the same spirit, nothing will give the author higher pleas- 

 ure than to assist, personally or by letter, teachers and students 

 in ncquiring or disseminating a knowledge of the Laws of 

 Hygiene ; and he would solicit the favor of their acquaintance, or 

 the continuation of it, upon the ground of community of opin- 

 ions, feelings, and interests.
