8 Mr. Bauer’s microscopical observations on the 
lour, variously distorted, and as hard as wood. The cavities 
of these grains were now completely filled with young 
worms, and these worms were, in every respect, the same 
as those with which I had inoculated my first seed grains ; 
and those specimens were now more than twelve months old, 
and, consequently, the grains and the worms within them 
were completely dry ; but after soaking them in water about 
an hour, the worms recovered their powers of moving, and 
were again as lively as those which were taken from the 
living plants. 
These experiments I repeated with grains from the same 
specimens, for five years and eight months, always with the 
same success ; but I observed that the longer the grains were 
kept dry, the longer they required to remain in water before 
the worms recovered their motion ; but after the expiration of 
five years and eight months the worms were really dead. 
The worms of the specimens which were the produce of 
my inoculated plants, retained their reviviscent quality for 
six years and one month ; and this is the longest time of sus- 
pension I have hitherto ascertained ; after that time the power 
of resuscitation ceased. 
The large worms, after they become dry, die, and never 
revive ; neither can the young worms within the eggs be re- 
vived, if the eggs have been but for a moment dry before the 
worms have extricated themselves. 
Experiments with such worms as had been revived in water 
before, and had been dried again, I repeated many times ; I 
soon found that those which had been kept the shortest time 
in water, recovered their motions soonest ; so that those 
which had been examined on the plain object-glass where
