‘the lobes themselves, or from the structure of other pheenoga- 
mous plants: the only cases of apparent, though doubtful, ana- 
logy that I can at present recollect occurring in Aphyteia, and 
perhaps in some Cucurbitacee. 
That part of my subject, therefore, which relates to the ana- 
logy between the male and female flowers in Cycadez and 
Coniferee, I consider the least satisfactory, both in regard to 
the immediate question of the existence of an anomalous ova- 
rium in these families, and to the hypothesis repeatedly re- 
ferred to, of the origin of the sexual organs of all phzenoga- 
mous plants. 
In concluding this digression, I have to express my regret 
‘that it should have so far exceeded the limits proper for its 
introduction into the present work. In giving an account, 
however, of the genus of plants to which it is annexed, I had 
to describe a structure, of whose nature and importance it was 
necessary I should show myself aware; and circumstances 
have occurred while I was engaged in preparing this account, 
which determined me to enter much more fully into the sub- 
ject than I had originally intended.

‘THE following summary account of the direction and force 
of the currents experienced in each day’s navigation, com- 
mences with the appointment of the Pheasant to convey the 
clocks and pendulums from Sierra Leone to the subsequent 
stations. Captain Clavering entered with much interest into 
the inquiry, and by his judicious arrangements and personal 
superintendence, until habits were established, the reckoning 
of his ship was rendered - little inferior, as an element in the 
deduction of currents, to the observed difference of latitude 
and the chronometrical difference of longitude. On leaving 
England, I had obtained from the Admiralty a supply of the 
logs invented by Mr, Massey, which being towed at a suffi- 
cient distance astern, to be cleared of the back-water occa- 
sioned by a ship's progress, registered her way by the revolu-
