Estimates of Cost for Chemical Supplies. 



In compiling this Collection it is assumed that physical instruction is imparted in a different 

 room from chemical instruction. If, however, the classroom is common to both branches, the objects 

 listed in the section "Apparatus, Supplies and Materials for General Use" can be entirely or partly 

 dispensed with if already available in the Physical Collection. 



It is further assumed that the "Equipments", and especially Lecture Table with gas, water 

 and electric leads, etc., Cupboards, Eeagent Stands, Tools and perhaps also an experimental Switch- 

 board, or an electric Transformer, Water Air Pump, Water Jet Blower, etc. necessary for the 

 Chemical Classroom, the Preparation Eoom and the Laboratory, are either available or will be ordered 

 separately.
