inoculation, is very évident. The dry weight m the séries AG is 

 stnkingly higher than in the other. Hardly any conidia were formed 

 in this séries and if se, it was only along the sides of the vessel; in 

 the centre the mycehum remained white. In the G G séries however, 

 the mycehum was black throughout. 



Very httle diastase is produced in A G, so that I did not think 

 it worth while to represent it graphically. In the case of GG how- 

 ever, this production is of importance. We see a fairly considérable 

 rise in both curves, viz. for diastase m mycehum + culture solu- 

 tion ( ) and also in the culture solution only ( ). Be- 



fore the maximum dry weight is reached, both curves descend. On 

 about the 9 day, the minimum of enzyme is found; m the culture 

 solution it m.ay even go down to zéro. Later however there is another 

 rise, which is even greater than that in the beginning.

In this case also abundant conidia were formed, so that soon the 

 mycehum was black throughout. This is true of ail cultures on 

 glucose and starch. The mycehum always formed a flat, conti- 

 nuous pellicle. Ondulations in it were only found m the very 

 thickest of them. 



The production of diastase is very similar to that of glucose 5%. 

 The first maximum is not so high and the subséquent fall is not so
