older Amber flora, probably owing as the professor thinks, to 
a change which had already taken place in the climate of 
Northern Europe. Many of the plants which occur in it are 
not found living in the region now, though very similar to 
the existing flora. The most numerous are Poplars, Alders, 
Ash, and several varieties of Conifera. With these were 
associated Gardenia, with fruit like a pea, a fig, Banksia, &c. 
As the Brown Coal extends over other parts of Germany, 
and elsewhere, and sometimes yields Amber, it will be 
understood that this product is not by any means confined 
to the Baltic area referred to in this paper, nor to the earlier 
Tertiaries. It has been discovered in Russia, in the Province 
of Grodno, and Italy, probably in Tertiary deposits of the 
same age also in Africa, Brazil, and South America, but 
whereabouts I am unable to state positively, but probably 
derived from some one of the Tertiary formations. It has 
been met with in Sweden, on the coast of the North Sea, 
and may yet be discovered in many other localities, when 
the stock is exhausted in the richer Baltic provinces, and the 
demands of trade compel the dealers to search for it else- 
where. Vast quantities are washed up on the shore near 
Memel, also in the Baltic, in the extreme North-East, and 
are thought to have been derived from certain Tertiary 
deposits containing Amber, in the large adjacent region of 
Russia and Poland, where Brown Coal containing Amber 
has been discovered overlying true Chalk. Stores of Amber 
still lie hidden in the interior of the country, and on the Baltic 
coast, though much still is no doubt buried under the sea, 
the Amber bearing stratum often lying too deep to be 
attainable. 
Besides the plants which are occasionaly found in Amber, 
the most interesting and remarkable fossils, are the insects,
