THE NATURALIST. 



in p. 84 of their " British Flora," that it 

 is "a plant almost peculiar to a southern 

 clime, and cannot be expected to be indi- 

 genous with us ; but as TrifoUum Bocconiy 

 Erica vulgaris, and other southern plants 

 are found wild, though rarely, in Cornwall, 

 why should not G. striatum be counted 

 indigenous too ? — J. C. Melville, Oct. 

 3, 1866. 



[In the "Journal of Botany" for Sep. 

 last, is a letter from Mr. A. H. Church, 

 in which he states ' ' I hare found repeatedly 

 in different places, all far away from culti- 

 vation, a geranium, which I cannot help 

 thinking is G. striatum. It is sparingly 

 distributed along the coast of South Corn- 

 wall, some miles on either side of Charles - 

 town, near St. Austell. If my determin- 

 ation of the species is correct, the plant 

 must be truly wild." This is further 

 testimony to Mr. Melville's opinion. 



The species is described in ' ' Botanical 

 Magazine," ii,p. 55 and has been previously 

 observed in Cornwall, also at Trevrew, 

 near Llanrwst, in North Wales. — Phyt.

THE NATURE AND COLOUR OF BLOOD. 



By E. Eoxton-Eirby. 



As is universally known the blood is a liquid of a beautiful scarlet 

 colour, and peculiar odour, circulating tlirough the heart, arteries, and veins 

 of animal bodies, serving for the nourishment of all their diversiform organs, 

 and the support of life. The nutrient fluid, in scientific nomenclature the 

 liquor sanguinis^ when in a healthy condition consists of the following 

 chemical constituents, — primarily of water, holding, in a dissolved condition, 

 albumen, fibrin, oleic, stearic, lactic, phosphoric, sulphuric, and hydrochloric
