whole work up to the metals in twenty weeks, and all the work given 

 in metals in eight or ten weeks. 



We confidently recommend Shepard's Chemistry to any teacher who 

 now uses, or who wishes to adopt, the laboratory method of instruction. 



Among its many new and valuable features, a prominent teacher 

 specifies the following : — 



i. Its excellent methods, which bring out the great educational force 

 of the science, and yield exceptionally large practical results. 



2. The logical arrangement of its subject-matter, introducing the 

 principles of the science by easy steps. 



3. Its conciseness and its completeness fully covering the beginner's 

 wants in the working laboratory. 



4. Its mechanical excellence, the typography being open and attrac- 

 tive, and the large type allowing the text to be read at a distance with- 

 out injury to the eyes ; the binding being such that the book will stay 

 open on the desk while the student is at work, and the color of the 

 cloth being such as is least affected by acids. 



5. The Appendix, which gives (1) Instructions for equipping the 

 laboratory ; (2) Directions for preparing all needed reagents ; (3) A 

 complete list of working materials ; (4) The impurities found in com- 

 mercial reagents ; (5) All the names by which reagents are known. 



The book is based upon plans and methods which have been em- 

 ployed in the author's laboratory throughout a series of years, and no 

 work has been incorporated in the text or in the exercises that has not 

 there been proven practicable. 



A wide correspondence with the best teachers in all parts of the 

 country shows that they are pursuing essentially the same plan. 

 Throughout the book the aim is to make the labors of the teacher as 

 light as possible, and to "place the laboratory work where it will do the 

 most good in the hands of the students." 



"This work and Remsen's Organic Chemistry (page 1 of this cata- 

 logue) form an admirable course for the presentation to the student 

 of the facts of inorganic and organic chemistry. " — Curtis C. Howard, 

 Prof, of Chemistry, Starling Med. Coll., Columbus. O. 



A Circular, suggesting various plans of shortening the course, as 

 well as a Special Circular, of interest to chemists and teachers of chem- 

 istry, will be sent on application to the publishers.
