In the further observations on growth, I availed myself largely 

 of this idea and its consequences, with results of considerable interest 

 and importance. 



The following measurements of the rate of growth of the germi- 

 nating filament (as contrasted with the longer older filament) were 

 made. The spore was sown in 3 per cent, glucose solution (to 

 which a little broth was added) shortly after 4 P.M. : the temperature 

 was 20 21 C. throughout. 



From 5 P.M. to 6.5 P.M. the spore had swollen and elongated to 3 /t, 

 and the measurements began at 8.10 P.M., when the germinal filament, 

 still in the spore, measured 6 ft.. 



At 8.40 P.M. the young rodlet had elongated to 9 fi i.e., it had 

 grown 3 /i in thirty minutes. At 9.45 it had grown another 9 ft. 

 From 9.45 to 11.0 P.M. it grew 12 fi. From 11.0 to 11.45 it had 

 grown 6 ft. 



The measurements were then discontinued till 10.35 next morning, 

 when 45 , additional had been added.
