THIS book is strictly an introduction to the study of the compounds 

 of Carbon, or Organic Chemistry, and is intended to meet the 

 wants of students in our scientific schools, medical schools, schools of 

 technology, and colleges. It is difficult to see how, without some such 

 general introductory study, the technical chemist and the student of 

 medicine can comprehend what is usually put before them under the 

 heads of "Applied Organic Chemistry" and "Medical Chemistry. 1 ' 

 The book is perhaps rather more elementary than most of the existing 

 small books on the subject, and is therefore, it is believed, better adapted 

 to the classes of students mentioned. It takes nothing for granted 

 except an elementary knowledge of General Chemistry. Special care 

 has been taken in selecting for treatment such compounds as will best 

 serve to make clear the fundamental principles. General relations 

 as illustrated by special cases are discussed rather more fully than is 

 customary in books of the same size ; and, on the other hand, the 

 number of compounds taken up is smaller than usual, though all which 

 are of real importance to the beginner are treated of with some degree 

 of fulness. Thus there is less danger of confusion than when a larger 

 number is brought to the attention of the student. The author has 

 endeavored to avoid dogmatism, and to lead the student, through a 

 careful study of the facts, to see for himself the reasons for adopting 

 the prevalent views in regard to the structure of the compounds of 

 carbon. Whenever a new formula is presented, the reasons for using
