\o 
The objects to be used in effecting this plan of illustration 
will be drawn from a great variety of sources, and it will 
take much time to make any one of the subjects complete. 
Much material can be obtained through commercial houses 
and from similar museums in America and Europe, without 
any great expenditure of money. 
Second Fioor. 
A. General Botanical Muscum. 
This is to be arranged systematically from the most lowly 
organized to the most complex plants, in sequence, illustrat- 
ing types of the natural families by specimens of the plants 
themselves, and by fruits, seeds, bark, leaves, roots and other 
organs, photographs, plates and drawings. 
s with the economic collections, the: material will be 
drawn from every available source, but in this instance more 
is to be expected from museums or collections already estab- 
lished than from commercial houses. 
B. Physiological Muscum. 
This collection will be planned to illustrate the phenomena 
and processes of plant life, and would consist mainly of 
models, drawings and specimens.
