I could not observe ail my solutions so long as I should hâve 

 wished to, because in many cases my supply gave in within a very 

 short time. It was therefore impossible to give observations which 

 had been made after an equal length of time in ail cases. I could 

 of course make the number of days, on which the observations were 

 taken, the same for ail séries, but then I should hâve to exclude ail 

 the results, which I obtained after the smaliest number of days, 

 during which those observations were made i. e. 6 days (in the 

 case of the 5% glucose séries). Besides, the results would hâve 

 shown nothing. Yet as they are, they show very clearly the in- 

 fluence of the increase in fungous matter, proving that this in- 

 fluence is directly proportional to the decrease of enzyme action. 



The séries on maltose gave verypoor and disconnected results hère. 



In the case of 0.1% starch + 4% glucose (9—13; 902), there 

 was no decrease in the liquids of the 3 and the 4 days. No 

 further observations were made. 



In the liquids from the 0.25% starch + 2.5% glucose séries 

 (7 — 13; 636.5) the following amounts were left after 6 days: 



in the solution of the 4^^ day 30% 

 18th „ 24% 

 19th „ 20% 

 21*'' „ 21 % 

 23*^ ., 12% 



Liquids from latter days did not loose more than about 1 5%. 



After standing for 12 days, the liquids from the 0.4% starch + 

 1% glucose séries (7 — 13; 357) gave the following amounts: 



in the solution of the 4"' day 54%

The influence of the inhibiting factors m this case is greater than 

 I expected to see, when considering the relatively small dry weight 

 of the mycélium.
