The two blocks between which the plaint tissues were pressed are 

 shown at (1) and (2). The juice escaped through a hole (3) in block 

 (1). The plant tissue was placed between the blocks (1) and (2), 

 which in turn were placed between the pieces of movable 4"x4" pieces 

 which are drawn together by bench-screws. (See page 158.)
