Xii TO THE TEACHER. 



dormant. The teacher should plan his work long beforehand, 

 that he may have plenty of time to procure needed material. 



Notes and Drawings. The student should make care- 

 ful notes of all his work in a note-book devoted to this sub- 

 ject. These notes should be accompanied by drawings of the 

 dissections and copies of diagrams placed on the blackboard 

 by the teacher, and of charts shown in the class-room. These 

 drawings should be made in color, using water colors, where 

 it will make the matter more clear, as in the subject of the 

 circulation of the blood. 



All the books named at the ends of the chapters should be 

 in the school library, and each pupil should be required to read 

 at least one in each subject. The author has required a re- 

 view of the books read to be placed in the note-book. 



It is not necessary that all the pupils should be reading on 

 the same subject at the same time, and in most schools it 

 would be impossible to furnish enough duplicate copies to 

 enable them to do so. Have the reading commence at the 

 beginning of the term, and require each to read a book every 

 week or two, according to a carefully made plan. 



One convenient form of keeping the notes is in the style 

 of a diary. The work of each day is entered under its date, 

 whether this work be of practical work or of recitation. 



Reform in Nomenclature. The expressions "up" and 

 " down," " front " and " back," are confusing when horizontal- 

 bodied animals, such as cats and rabbits, are used to illustrate 

 human anatomy (and we must use such forms) ; we should 

 use these terms : anterior meaning toward the head ; poste- 

 riory toward the tail ; dorsal, toward the region of the back ; 

 ventral, toward the region of the belly ; lateral, toward either 

 side ; proximal, toward the central axis of the body ; distal, 

 away from the central axis of the body. Right and left refer 

 to the right and left of the animal and not of the student.
