Bot. Zeit. 1862, p. 73 (continued, with interruptions, to p. 105). 
Embracing the following heads:—1. Experiments on Defoliation 
of the Weymouth Pine. Chiefly to ascertain the influence of 
the foliage on the amount and relative position of the deposit of 
wood, and also the extent to which the reserve materials stored 
in the tree cooperated in the formation of the wood. 2. Experi¬ 
ments on ringing pendant branches. The results the same as 
upon erect stems. 3. Besult of pressure in a spiral direction 
upon the bast-layer of the Weymouth Pine. 4. Binging experi¬ 
ments on the Black Pine. 5. Experiments with cuttings. 6. Does 
the bast-layer take part in the ascent of the sap ? 7. On the 
* Tears ’ of woody plants—the dew-like drops observed on the 
buds, etc. of various trees in spring. 8. The ‘ Bleeding ’ of the 
Oak ; and, 9, of the Walnut. 10. On the loss of the power to 
conduct sap by long exposed, wounded surfaces of trees. 11. On 
the movement of the Ptycho de-sap. (The protoplasm■ circulating 
between the outer and inner Ptycho de-membranes: the outer 
Ptychode of Hartig is the Primordial utricle of y. Mohl). 12. 
On the motion of the sap in the ‘ laticiferous ’ tissue.

of economic species, with their modern Greek and Albanian vul¬ 
gar names, observations are added upon their culture and appli¬ 
cation when worth notice. An Appendix is devoted to wild es¬ 
culent herbs—the so-called Xayctm.

- - - Becherches experimentales sur la formation des couches 
ligneuses dans le Pircunia. A. S. N. ser. iv. xvi p. 218. In 
Pircunia the growth of the wood is very rapid, several layers 
being formed each year. Hence it suggested itself as suited for 
the author’s experiments, instituted in order to find out how far 
the zones of cellular tissue deeper than the cambium layer,
