6 A. E. HILTON ON THE FORMATION OF SPORANGIA 



of Stemonitis is a good object for the microscope ; but it is 

 only a by-product, and of no biological importance. When the 

 spores disperse to fulfil their next function, all other structures 

 are left behind to perish ; but we know that if the life which 

 created them survives, the forms we have admired will reappear.
