62 Calvert and Boodle. — On Laticiferous Tissue. * 
Fig. 7, there appeared to be a connection with another vessel slightly below the 
plane of the section. At w, Fig. 8, the remains of a partially absorbed wall are 
seen. (Fig. 7 x 700, Fig. 8 x 350.) 
Fig. 9. Part of a radial section through the pith of an older stem, near a node. 
A laticiferous vessel l. v. is shown passing between pith-cells with thick, pitted, 
lignified walls. The contents have not a continuous definite outline, like that of 
the other sections, probably owing to difference of treatment. This section was 
cleared with chloral-hydrate and stained with borax-carmine. ( x 700.)
