Case it is not affected to any considerable extent by the opposite 
incisions. _ These facts are regarded by the authors as opposed to

that the movement takes place in the cell-cavity. In the Con- 
ifere the water can still move from tracheid to tracheid notwith- 
standing the incisions; while in Angiosperms, all the vessels 
being cut, the conduction is rendered difficult.” Jour. Roy. Mic.
