PUBLISHERS' NOTE TO REVISED EDITION 



THE sales of this work have in the last few years become so large that 

 it has been found necessary to make new electrotype plates. The pub- 

 lishers have taken advantage of this to have the book carefully examined 

 with a view to discovering whether or no it conformed in every respect 

 to the latest advances in knowledge of the subject. Very few changes 

 in the text have been found necessary, and these few are of such a minor 

 character as not in any way to prevent the use of the new and old 

 editions in the same class. 



The main changes to be noted in this edition are as follows : Topical 

 Outlines have been added at the end of chapters, which it is believed will 

 be of great value to pupils and teachers. In some of them additional 

 information has been given, which it has not been thought best to include 

 in the text, but which may be found useful for the teacher in his class 

 work. 



Such slight changes have been made in the text as were necessary to 

 meet the requirements of the laws of the several states with respect to 

 the influence of alcohol and narcotics. The book Will be found to comply 

 fully with all such laws and with the intelligent temperance sentiment of 

 the country. 



A chapter on emergencies has also been added, which, it is hoped, will 

 give the book a permanent value in the home and be of service to the 

 many " first aid to the injured" classes that are being formed in all parts 

 of the country. 



A number of new illustrations have been scattered through the book. 

 The only other change of any prominence is in the experiments, which in 

 the former edition have been in the appendix, but are now transferred to 

 the body of the book as footnotes, where they will be more accessible as 

 an aid to the teacher in more interestingly presenting the subject to the 

 class. All the experiments, as well as the anatomical demonstrations, 

 are simple, and the teacher will have no difficulty in reproducing them. 

 Should there be failure at first, a little patience and a few trials will soon 

 be followed by success. All complex dissections on recently killed 

 animals, as well as all vivisections upon frogs, etc., have purposely been 

 omitted, not only because they are unnecessary in teaching the rudiments 

 of anatomy and physiology, but also because they would create disgust 

 and abhorrence in the majority of pupils. 



The publishers gratefully acknowledge their indebtedness to D. L. 

 Bard well, Superintendent of Public Instruction, Binghamton, New York, 

 who has made such changes in the text as were necessary to bring it into 

 perfect accord with the latest Syllabus of the Board of Regents of the 

 State of New York.
