PISCES 403 



26. Trace, touch, taste, smell, sight, and hearing through the inver- 

 tebrate branches. 



27. Trace evidences of automatic and reflex action. Purpose of these 

 actions to animals? 



28. Egoistic Instincts. — (Instincts for the good of the individual.) See 

 Laboratory Guide, p. 14, for a list of these instincts and give invertebrate 

 examples of each one. 



29. Altruistic Instincts. — (Instincts for the good of the race.) See La- 

 boratory Guide, p. 14, for list and find examples of each one among the in- 

 vertebrates. 



30. Emotions. — Laboratory Guide, p. 16. Plnd invertebrate examples of 

 each. Purpose of emotions in the existence of invertebrates? 



31. Trace invertebrate sounds, memory, intelligence, and reason, if any. 

 State the purpose of each to animals; to man. 



32. Compare the invertebrate body-structvire with that of the chordate 

 (vertebrate), as to similarities and differences. 



33. Have they both the nine systems named in 16, under Worms? 



34. Mind manifestations of the invertebrates and vertebrates. Do they 

 agree, or do they differ in degree and kind? 



35. Is the invertebrate body-structure superior or inferior to the chordate 

 one? The mind manifestations? Is the invertebrate body-mind superior 

 or inferior to the chordate body-mind? 



36. Will either body-mind tyj)e ever advance to a higher type of body- 

 mind? Will there ever be a higher type of body-mind or of mind-body? 

 Why do you think so? Will either type now existing ever degenerate? 

 Become extinct? 



PISCES 



1. Fins. — How do you account for the anterior and posterior paired 

 fins of fishes being placed so close together as compared with the paired 

 limbs in other chordates? Does the body locomotion of fishes have any- 

 thing to do with this arrangement? 



2. Gills. — How do you account for the presence of gills instead of lungs 

 in fishes? Advantages? Disadvantages? 



3. Fins and Scales. — Why have fins and scales? Is locomotion con- 

 cerned in this? 



4. Self-defense. — Name all the ways and means of self-defense used and 

 possessed by fishes. 



5. Locomotion. — Body motion, limb motion, or both? Name all the 

 modes of motion and locomotion of fishes. 



6. Enemies. — Name all enemies of fishes, both animate and inanimate. 

 How do fishes combat or escape their enemies?
