ADMISSION AND CLASSIFICATION. 41
same book as a guide, or some other book of a similar character,
representing eighty hours of actual work ; the notes upon this, care
fully written out, must be presented at the time of the examination,
and this record should be endorsed by the teacher at the close of each
day's work. Problems in the calculation of gas volumes, and in
stoichiometry will be included in the examination. Finally the appli
cant will be examined on such on amount of qualitative analysis as
can be accomplished in eighty hours of actual practice in the labora
tory. A carefully written and endorsed note book of this work must
also be presented at the time of the examination.
Laboratory as well as oral or written examinations will be held in
those parts of the work requiring laboratory practice. The nature and
' '
' '
scope of the problem work is shown in Trevor's Chemical Problems.
3. Botany. The student should aim to acquire a knowledge of the
general laws and fundamental principles of plant nutrition, assimila
tion, growth, etc., as exemplified by plants chosen from the different
groups, as well as the general comparative morphology and the broad
er relationships of plants.
The following brief synopsis will suggest the topics and methods of
study :
Study protoplasm in plants representing different spiro-
groups, as
gyra, mucor, nitella, and in the tissues of some of the higher plants,
in order to demonstrate that this substance, though occurring in
widely different plants, is fundamentally the same,
similar manner to treatment with certain simple reagents.
and reacts in a
Study absorption and osmose in plant cells, such employing plants
as spirogyra, mucor, the cells of some higher plant as the beet, and in
the root hairs of a seedling plant ; test the effect of salt solutions in
plasmolyzing the cells of these plants, then the restoration of turges-
cence in the same cells, and the movement of the protoplasmic mem
brane to demonstrate the part it plays in the process of absorption in
plants.
Study nutrition comparison of soil and water cultures by in seed
lings ; also root pressure
study ; turgidity in plant parts and cell
masses ; transpiration ; the path of movement of liquids in higher
plants, and the general structure correlated with these processes ;
study nutrition of parasites (carnation rust, dodder), of ; mushroom.
Study the movement of gases in carbon assimilation as shown by
spirogyra, vaucheria, elodaea, etc., in respiration as shown in germin
ating seeds ; study forms of chlorophyll bodies and the formation of
starch, noting the parts of the plant where these processes take place,
and using for comparison, spirogyra, zygnema, vaucheria, oedogo-
