STRUCTURE AND PHYSIOLOGY OF 
FLOWERING PLANTS. 
GENERAL LABORATORY DIRECTIONS. 
Be as quiet as possible while in the laboratory. 
Keep your table in order; do not write on it, or mar the 
surface in any way. Thoroly wash all dishes and 
apparatus immediately after using them, and return them 
to their proper places. 
Notes will be required on all work in the laboratory 
unless otherwise stated in your laboratory directions. 
See that your notes are as nearly perfect as you can make 
them with regard to neatness, diction, spelling, grammar, 
punctuation, and capitalization. Your notes should con- 
tain descriptions of what you do and see. Try to make 
your descriptions clear enough so that by reading them 
any one who knows nothing at all about your work could 
get a clear idea of what you are trying to describe. All 
existing facts should be put in the present tense. Use 
the third person rather than the first. Occasional quo- 
tations are admissible, but if anything is quoted use 
proper marks to indicate it. All notes must be written 
in ink, 
In correcting notes the following abbreviations will 
be used: Not definite, nd; not clear, nc; description be- 
fore name, dbn; incorrect with reference to, (1) subject 
‘matter, °; (2) grammar, ¢; (3) diction, d; (4) punctua- 
tion, x; (5) spelling, s; (6) paragraph, p. Before correct- 
ing your notes always study the object described again.
