Experiments with Cutting Leaves of Plants.

and looked somewhat dead at their edges. In about six weeks' 

 time the leaves fell from the plant. The cuts on the leaves of 

 the Geranium at first looked as though thev were inclined to 

 re-unite, very minute filaments formed at the edge of the cuts 

 looking as if they might knit the cut parts together again, eventu- 

 ally the leaves turned yellow, and dropped from the plant The 

 cut leaves of the Primula became ^•ery ragged at the edge of the 

 cuts the leaves became discoloured and decayed, and thev 

 finally shrivelled up and died. The centre cuts in the leaves of 

 the Calceolaria spread in all directions, more so than the cuts 

 at the edge of the leaves. After a time the leaves became limp 

 and the cuts becoming black, in the end the leaves died The 

 Cineraria's leaves that were cut curled up very much at the 

 edges, the centre cuts had several little notches at the edges 

 they split away from the main cuts, and all the cut leaves died
