It will be seen that the punctured internode is longer than the internode below, as in the normal stem. Compare with the injected specimens. Specimens 57, 58, 59, 60, 61. Distilled Water Injections The injected internode is seen to be the shortest of all. The plants seem to have averaged somewhat older than the preceding. Specmiens 62, 63, 64, 65, 66. NEW CELL FORMATIONS IN PLANTS 289 Lithium Carbonate Injections. 1:10 Saturated Aqueous Solution This series of specimens shows a very prominent stunting of the in- jected internode. Specimens Z3, 34, 35. Tissue Reactions Following the Injections of Herbaceous Plants When the injection was made, two holes were opened in the stem. The liquid, injected thru one hole, ran down the side of the cavity till this was full up to the hole left for the escape of the air. Then the excess fluid escaped thru this hole. The needle was withdrawn, the outside of the stem wiped dry, and a piece of gauze bandage smeared with melted grafting wax was wrapped around the wound. Such were the conditions when the fluid began to act on the stem. Some- times less fluid was injected, and some of the other arrangements were different in the earlier experiments, but the general conditions were the same thruout. It will be seen that there were
