spores had germinated at the end of fourteen hours, but the 
appearance of the hyphz under these conditions was in strong 
contrast to those under normal conditions. Instead of being 
long, slender, and tapering, like normal hyphe, they were 
short and blunt, and often enlarged at the ends as if they were 
growing against some object which was offering resistance. 
It should be added that at the end of the next twenty-four hours 
the hyphz had so overcome the influence of the ether that they 
had assumed the normal form, size, and stage of development, 
?.¢@., they had already produced spores. The fact that these 
plants had attained the same size as the plants in the control 
experiments, would indicate that growth must have been acceler- 
ated after the first fourteen hours, since at that time they were 
much dwarfed. 
In the chamber that contained 5° of ether, the spores had 
simply become enlarged and granular at the end of fourteen 
hours, and it seemed as if they were unable to push out a tube at 
any point. At the end of the next twenty-four hours, many 
of these spores had germinated, and the hypheze produced 
were similar in appearance to the hyphe in the control experi- 
ments, except that there was no indication of spores or of. 
spore cases. 
When the spores were placed in an atmosphere containing 
10“ of ether, germination was retarded for about ten days, at the 
end of which time many of the spores germinated without 
removal from the ether atmosphere. If the spores were removed 
at the end of five days and placed in an ether-free damp cham- 
ber, nearly all of them germinated within fourteen hours, but _ 
the subsequent growth was not so rapid as it was during the first 
twenty-four hours in the control experiments. At the end of 
the second twenty-four hours, the hyphz showed rapid growth 
and a few spores were produced, but they were far less numerous 
than in the control experiments. At the end of ten days when 
the spores had begun to germinate, some of them were removed 
and placed in an ether-free atmosphere, and these spores grew 
more rapidly than those which remained in the ether atmosphere.
