The appearance of the various structures and tissues of the human 

 body as revealed by the microscope possesses a curious fascination 

 for every observer, especially for young students. No one ever forgets 

 the first look at a drop of blood, or the circu- 

 lation of blood in the web of a frog's foot as 

 revealed by the microscope. 



11. Dissection in Elementary Schools. A 

 few simple dissections which can be made 

 with fresh beef joints and legs of chickens 

 and turkeys will answer every purpose in the 

 elementary grades. A discreet teacher should 

 rarely advise his pupils to dissect a dead cat, 

 dog, frog, or any other animal. Instead of 

 actually dissecting, the pupils should examine 

 specimens or certain parts previously dis- 

 sected by the teacher, as the muscles and 

 joints of a sheep, the heart of an ox, the eye 

 of a codfish, and so on. 



12. Teaching Surface Anatomy and Land- 

 marks of the Body. In elementary work it is 



only fair to state that comparatively few points FIG. 203. A Compound 

 concerning the surface anatomy and land- Microscope, 



marks of the body can be defined or located 



with precision. A certain amount of work in this direction can, how- 

 ever, be done, even in elementary schools, with ingenuity, patience, 

 and a due regard for the feelings of all concerned. For example, the 

 student may be taught to examine the muscles and other parts of his 

 own face, his teeth, tongue, and palate, and the bones and muscles of 

 his shoulders and limbs. Two friends may thus work together, each 

 serving as a model to the other. 1

 regard to the manipulation and use of the microscope the student is referred to any 

 of the standard works on the subject.

 for experiments consult the advertising pages of leading educational publications.

 of a brief course of study concerning surface anatomy and landmarks of the body.
