268 THE STRUCTURES OF PITCHER PLANTS. 
canals could also be seen dipping deeply down into the parenchyma of 
the lid. The appearances seen strongly reminded me of the effects of a 
poisoned wound of the finger upon the superficial lymphatics of the 
forearm. (Plate VIIL., Fig. 7.) 
In the lip of Darlingtonia I have seen them with nucleated lacunar 
expansions (Fig. 8) quite identical with similar appearances which I have 
already described in the human umbilical cord, (Proceedings Roy. Soc., 
No. 163, 1875.) In many cases, however, they do not possess distinct 
walls, but seem to be mere tubular interspaces between cells. 
The last structure found in pitcher plants to which I shall make 
special reference is the secreting gland. These are limited to the 
Cephalotus and Nepenthes. In the former they are buried in a pit 
excavated in the parenchyma and lined by epithelium. They are 
constructed of modified epithelium, arranged very much like the 
elements of the glands of the Drosera and Dionza as described by 
Darwin. They are probably also absorbents, their two actions 
alternating ; but of this I have no evidence save the analogy with the 
glands of Drosera.

SCIENTIFIC NAMES.—IT. PRONUNCIATION. 
BY W. B. GROVE, B.A. 
(Continued from Vol. I., p. 152.) 
The rules concerning the pronunciation of words come under two 
heads, (1) as to the sound of single letters, (2) as to the syllable upon 
which the accent falls. Upon the second head, in the case of Latin, at 
least, there is very little difference of opinion, but with regard to the 
first the ideas of many persons are in a transition state. The old-estab- 
lished idea was that each nation should follow the precedent of its own 
language in determining the sound of the various letters in Latin words. 
But, though this was the theory, the practice, at least among our- 
selves, was very different, and the accepted model was a combination of 
diverse styles, together with a little of no style at all. 
In the case of scientific nomenclature the confusion is worse 
confounded on account of the medley of sources from which it is derived. 
Sometimes when a native name of a plant or animal formed part of the 
scientific name, or when some discoverer with an appellation full of unclas- 
sical consonants and diphthongs was to be immortalised, an attempt was 
made to diminish the incongruity by Latinising the word on the same 
principle on which the Romans themselves converted the words which 
they adopted from other nations, as when they changed Caradoc into 
Caractacus. But thisis seldom done now, and the practice sometimes leaves 
the original form of the altered name uncertain, and thereby fails after 
all to immortalise anybody in particular. No apology is now thought 
needful for placing a word which is pure Greek side by side with one 
which is pure Javanese, e.g., Strychnos Tieuté, a tree which grows in Java. 
The old principles will no longer suffice, and any change will most likely
