2C8 Germination of Maize Grain. 



61. Purple colour of Glass increased by light. — M. Fara- 

 day has found that by the exposure of plate-glass with a pur- 

 ple tinge to the sun's rays, during nine months the purple 

 tint had increased considerably, while pieces of the same 

 glass kept in the dark had suffered no change. — Quart. Journ. 

 M. 31. 



62. Flora of the Greek Archipelago. — A full and exten- 

 sive Flora of the Greek Archipelago, and the shores and 

 islands oftheEuxine, by M. Diimont D'Urville of the French 

 navy, has appeared among the transactions of the Linnaean 

 Society of Paris. Those countries, so long under the semi- 

 barbarian power of the Crescent, have never, until now, been 

 botanically explored since the days of Hippocrates, and of 

 the Grecian botanist Theophrastus, save partially by that pa- 

 triarch of the natural sciences, Tournefort. M. D'Urville 

 was well acquainted with Grecian literature, and has affixed 

 to each plant its own Hellenic denomination, as given in an- 

 cient classical authors. — Dr. Pascalis's Address. 



63. Effects of an earthquake on the vegetation of wheat. — 

 It is a remarkable circumstance, that since the great earth- 

 quake of 1687, no wheat will grow on the coast of Peru. In 

 some places, indeed, a little is raised ; but it is very unproduc- 

 tive. Rice, on the contrary, yields a great return. Before 

 the earthquake, one grain of wheat yielded two hundred 

 grains. — Edinb. Phil. Journ. Vol. X. 



64. Maize grain remarkably retentive of the power ofGer' 

 minating. — It is worthy of notice that the maize which is found 

 4n the graves of the Peruvians, who lived before the arrival of 

 Europeans in that country, is still so fresh, that when planted, 

 it grows well, and yields seed. — Ibid,
