462 Mr. E. J : QuEKETT on the Ergot of Rye, 
leaving the field of view, but possessing a tremulous movement, slowly ap- 
proaching.and retreating about their neighbours. 
Having witnessed this for some time, and satisfied myself that the move- 
ments were such as are common to particles known as “active molecules," the 
object was set aside, covered with the piece of mica used in the previous ob- 
servation, and placed under an inverted glass to prevent the evaporation of the 
water. 
On examining it the next day, it was found that a few still retained similar 
movements to those witnessed the previous day, but the greater number pre- 
sented appearances of commencing germination, in the various ways which 
here follow. 
The most common method is that of the sporidia emitting a tube or tubes 
from some uncertain point or points (Tas. XXXIII. B. fig. 4.), but generally 
opposite the spot where a green granule is lodged in the interior. This tube 
increases to an uncertain length, and contains throughout its interior similar 
granules, arranged at short but generally equal distances between diaphragms, 
about as far from each other as they are in the interior of the sporidia ; these 
tubes ultimately separate into fragments constituting as many fresh reproduc- 
tive bodies. 
t 
In many other instances the sporidia, instead of producing a tube, 
j give ori- 
Sim, opposite one of the granules, to a minute bud; this little point increases, 
becomes hollow, and ultimatel 
Y Separates from the parent as a perfect spori- 
dium, frequently however before its separation showing an indication of pro- 
ducing a similar one from itself. (Tag. XXXIII. B. fig. 5.) 
Another method of increase 
. membrane composing the pari 
: forming à flat pateh, which k 
amongst these singular germs is that of the 
etes of one of the sporidia breaking down, 
viding them into two parts, each of which 
different states of which are re-
