Estimates of Cost for Chemical Supplies. 



Estimates as to Equipments: see Vol. I. 



The prices may be changed for platinum goods at the time of ordering in proportion to th< 

 price prevailing for platinum. 



Collection 5. 



This Collection contains the articles designated as generally necessary and desirable in the "Standard Code" 

 (further particulars on p. 1075). A Collection of Chemicals in small quantities, with bottles for same provided with 

 inscription, also in small quantities, is appended. 



Apparatus, Supplies and Materials for General Use. 



These objects are selected conforming the collection 

 No. 3 re Physical apparatus and can be dispensed with when 

 a common class room is employed for physics and chemistry.
