pears to be mastieated wood or straw, mixed up with some glutinous fluid,

Cuctllus simplex. — Sir, The following is a drawing ( fig. 20.) of two 
fossil shells in my possession, which appear to be the Cucillus simplex of 
Rumphius (tabula 59. litera B). They are firmly united together; but

Ladanum was procured in the time of Dioscorides by goats, as your cor- 
respondent, Professor Thomson, observes 
(Vol. I. p. 408.) ; but Tournefort informs us 
that it is now gathered by means of a sort of

rows to a long handle, of which he gives an 
engraving. (fig. 21.) When Tournefort 
was in Crete he went to visit the district 
where the ledon, or Cistus créticus, grows, 
and saw a set of peasants, in the hottest time 
of the day, busily employed in flogging the 
shrubs with these whips, till they were 
covered with the ladanum, and they then 
scraped off the gum and prepared it in lumps 
for sale. — P. in B. August. 1829.

of leaves? — MW. F. Oct. 1829.

my meteorological observations for last year. 21 a
