When the rest of the substance of the cell-wall has been dissolved in concentrated sulphuric acid, it remains (in fine transverse sections) as a delicate net-work; if, on the other hand, the cells are isolated by boiling in potash or nitric acid, this middle lamella is dissolved, while the rest of the cell-wall is preserved, as in all wood-cells and v

The crystals of calcium oxalate which are imbedded in the middle lamella of a common cell-wall, such as those found in the soft bast of Coniferae, have evidently- been formed in the very spot where they occur. Pfitzer has shown, on the other hand, that the crystals found in Citrus vulgaris are formed in the cell-cavity, and become enclosed at a subsequent period by cellulose secreted from the surrounding protoplasm, which then coalesces in its growth, at one or more spots, with the cell- wall.

At these points, known as simple pits, the original middle lamella (the pit-mcnihrane, Fig. 14, A, pm.) alone separates the adjacent cells. In these cases the bulk of the protoplasmic connections (cf. p. 24) pass through the pit-membrane. Good examples of simple pits are seen in sections of Elder pith (Fig

This disorgani- zation is apparently due to an enzyme which attacks particularly the middle lamella.

Pre-Harvest Fruit Drop 243 It is possible that ethylene production by the maturing fruits may accentuate the tendency to abscise. Ethylene is produced by ripening apples (Gane, 1935) and also brings about abscission in general (Goodspeed et al, 1918). The abscission of mature apple fruits takes place principally as a result of a weakening and ultimate fracturing of the middle lamella of cells in or near the abscission zone (McCown, 1943). Auxins ap- plied to the fruit prevent the development of these changes in the middle lam
