Now for the general results. Of the eighteen leaves on 
which bits of meat were placed on the right or left sides of 
the disc, eight had a vast number of tentacles inflected on 
the same side, and in four of them the blade itself on this 
side was likewise inflected ; whereas not a single tentacle 
nor the blade was affected on the opposite side. These 
leaves presented a very curious appearance, as if only the 
inflected side was active, and the other paralysed. In the 
remaining ten cases, a few tentacles became inflected beyond 
the medial line, on the side opposite to that where the meat 
lay; but, in some of these cases, only at the proximal or 
distal ends of the leaves. The inflection on the opposite side 
always occurred considerably after that on the same side, 
and in one instance not until the fourth day. We have 
also seen with No. 5 that bits of meat had to be added thrice 
before all the short tentacles on the opposite side of the disc 
were inflected. 
The result was widely different when bits of meat were 
placed in a medial line at the distal or proximal ends of the 
disc. In three of the seventeen experiments thus made, 
owing either to the state of the leaf or to the smallness of the 
bit of meat, only the immediately adjoining tentacles were 
affected ; but in the other fourteen cases the tentacles at the 
opposite end of the leaf were inflected, though these were as 
distant from where the meat lay as were those on one side of 
the disc from the meat on the opposite side. In some of the 
present cases the tentacles on the sides were not at all affected, 
or in a less degree, or after a longer interval of time, than 
those at the opposite end. One set of experiments is worth 
giving in fuller detail. Cubes of meat, not quite so small as 
those usually employed, were placed on one side of the discs 
of four leaves, and cubes of the same size at the proximal or 
distal end of four other leaves. Now, when these two sets 
of leaves were compared after an interval of 24 hrs., they 
presented a striking difference. Those having the cubes on 
one side were very slightly affected on the opposite side ; 
whereas those with the cubes at either end had almost every 
tentacle at the opposite end, even the marginal ones, closely 
inflected. After 48 hrs. the contrast in the state of the two 
sets was still great; yet those with the meat on one side now 
had their discal and submarginal tentacles on the opposite 
side somewhat inflected, this being due to the large size of 
the cubes. Finally we may conclude from these thirty-five
