A BIOMETRIC STUDY OF THE CONIDIA, ETC., 



It will be clearly seen that in the case of Macrosporium 

 a curve closely approaching the Normal curve is p:iven • On 

 the other hand, a most complicated fiRure is given by 

 Altcnmria. The interpretation of this graph of the measure- 

 ments of AUcrvdria presents many difricultics, but it is pro- 

 bable that it represents a composite curve, consisting of a 

 series of smaller overlapping and intersecting curves. Each 

 of these smaller curves possibly corresponds to a conidium of 

 fixed position with reference to the conidiophore, and in re- 

 lation to the other conidia associated in the chain with it. 

 The data accumulated are insufficient, however, to develop 

 these details and confirm this suggestion.
