DIRECTIONS FOR LABORATORY WORK 

 I. GENERAL CONDUCT 



1. Remember that other people are working near you. Be 

 careful to make as little disturbance of any sort as is absolutely 

 necessary. 



2. All work must be done independently, both in the field 

 and in the laboratory. This applies to notes and drawings equally. 

 Any zvork copied from any source other than your own direct 

 observations will be referred to the students' honor commission. 



3. All work must be done in the laboratory. Under no con- 

 dition will permission be granted to finish or make up work out- 

 side the laboratory. 



4. The note book bearing name, section and desk number 

 on the inside of the front cover is to be left on the table at the 

 end of each laboratory period. 



5. In connection with the foregoing rule no notes may be 

 removed from the laboratory until they have received a final 

 grade except in rare cases under special arrangements with the 

 instructor in charge. 



6. Learn to work independently. When you have a ques- 

 tion, the answer to which is not directly available from the study 

 of your specimen, read ahead several sentences in the outline be- 

 fore asking for information. Look in the Glossary before asking 

 for tlie meaning of any term. 



7.* In getting material from the preparation table always 

 ask an Assistant for it. Very often the cultures and material are 

 of such a nature that great care must be exercised to prevent de- 

 struction. 



II. LABORATORY RECORDS 

 A. DRAWINGS
