Erythraeoides, Glauca floribus albidis occurs on the _Chummums_.

_16th_.--Regaled with a library: "Calumny and detraction," says
Boerhaave, "are sparks, which if you do not blow them, will go out of
themselves."--_Murphy's Johnston_, Vol. IX. p.34.

In Johnston's Life of Drake, p.99 to 100, are some admirable remarks on
those minds, that disapprove of every strikingly novel scheme, and from
which a good motto might be chosen, should any national system be
proposed in Botany.

What were Sir Thomas Browne's five sorts of vegetables, and what were his
remarks on the form of plants and laws of vegetation?--_See Johnston's_
_Works_, Vol. IX. p.296.

CHAPTER XXI.

_From Cabul to Kohi-Baba_.

_July 17th_.--Proceeded from Cabul to Shah Bagh; cloudy weather,
occasionally a very slight shower during the last few days, depending
probably on the Punjab rains. To-day, observed a small green
caterpillar, climbing up a fine thread, like a spider's web, which hung
from the fly of the tent; its motions were precisely those of climbing,
the thread over which it had passed was accumulated between its third
pairs of legs; it did not use its mouth.

I did not ascertain whether the thread was its own production or not; if
it was, it must have come out of its tail.

_24th_.--The fish in the Cabul river here are, a Loach, an Oreinus, and a
Barbel; none of these grow to any size, as there is but little water left
in the river in consequence of the drain for extensive cultivation on
both the east and west sides of the city.

Small specimens of these fish, especially the Loach and Oreinus, are
found in the canals or larger watercuts, in which the current is slow and
regular. It is curious that in the canal near the Shah Bagh, which has
been lately turned off above the Cantonment, all the specimens of the
Loach left in the pools of water were dead, while the Oreinus did not
appear to have suffered.

This Loach is a Cobitis propria, it has the usual form of that genus, the
spots are disposed irregularly, rarely becoming banded. The shape of the
head is curious, the forehead being prominent, this gives the mouth an
appearance of unusual depression. {479}

The country both on the east and west sides of Cabul may have been
formerly a lake. Such indeed would seem to have been the origin of all
the valleys in which there is an expanse of tillable ground, and not mere
strips confined to the banks of
