GENERAL DIRECTIONS xi 



6. Follow the directions precisely. Do not cut anything or remove anything unless 

 specifically directed to do so. 



7. Your laboratory grade is partly determined by the kind of dissections you make. 



Materials 



1. But one specimen of each animal is allowed to each student. Each student will be 

 given the necessary specimens and will retain them to the end of the course. Do not discard 

 any animal until the manual so directs. 



2. The smaller materials which are provided for the class as a whole should be returned 

 to the bottles or jars from which they came as soon as you have finished studying them. 



3. The larger specimens will be kept in large cans. Each table will be allotted the necessary 

 number of cans. Students will attach tags bearing their names to their specimens and 

 keep them in the cans when they are not in use. 



4. Specimens must always be kept moist and must never be allowed to dry up, as this 

 ruins them for dissection. Do not go away and leave your specimens out on the table. When 

 ready to leave the laboratory, wrap the animals in moistened cheesecloth provided in the labora- 

 tory and put them into the cans. See that the cans are always covered. 



5. Students who, through their own carelessness, render their specimens unfit for further 

 dissection will have to pay for new specimens. 



6. The skeletal material provided in this course is expensive. Handle it with care. Be 

 particularly careful with skeletons preserved in fluid.
