So that both nitrogenous and potash manures will probably be 
required in the future to keep up the yield from the same plantation. 
Fruit of Erythroxylon Coca, 
The fresh ripe fruit weighed, on an average, ‘158 gram each ; they 
were bright scarlet,in colour, and possessed a distinctly sweetish taste, 
but though masticated at various times, no physiolgical action on the 
mucous membrane of the mouth was observed, Dried in vacuo over 
sulphuric acid, the original tint was only slightly deepened, and this 
method of desiccation was employed in preparing the fruit for 
analysis, 
Microscopically described, the fruit from without inwards presents 
firsta single row of brick-shaped cells forming the epidermis ; within 
them is a single row of very large cells containing a mass of 
starch granules and scarlet colouring matter, Next comes the pulp, 
composed of parenchymatous cells, containing starch and granular 
matter. Then the shell, composed of an outer layer of stony cells, 
like bone cells, which are of considerable length ; within this layer is 
a row of scalariform vessels, and then several rows of pitted vessels. 
Then the almond, the cells of which are full of starch. 
The petroleum ether extract was a deep reddish semi-solid residue, 
which, on microscopic examination, was found to contain lamelle and 
needles of aclaret colour. It contained no alkaloid, and melted at 
34—35° C. A portion was saponified with alcoholic potash, and when 
cold agitated with ether. At 189—191° this extract melted to aclear 
yellow ati which cooled toa brittle transparent mass. Heated 
between wat ys, a white sublimate was obtained, 
but the saeiatts was far too nadie to admit of a melting point
