A BULB 



PREPARATIONS FOR WORK 



Each student must be furnished with a dry hyacinth bulb. Other specimens 

 which have been placed in glasses, and which have begun to grow should be at hand 

 so that there is one at least for each two students.

 of the bulb, and cut it fairly in half. If 

 necessary, slice away the bulb until the 

 flower-head is quite distinctly seen in
