for he sowed, in the garden of Erlangen, seeds of the T. officinale, 

 and obtained 1 T. palustrey 2 T. erectum Hoppe. T. leptoccpha- 

 lum Reich. ; 3 T. nigricans Rit. ; 4 T. corniculatum Rit. ; T. 

 officinale. — (Arm, de Scien. Nat, Aug. 1834.) 



V. — Plants of Arabia, Palestine and Egypt. 



M. Bor6 (Ann. des Scien, Nat, i. 1,) formed a considerable her- 

 barium during his travels in these countries, amounting to 233 species, 

 and belonging to 45 families. Several of these are natives of Britain, 

 as, Sargassuni vulgare ; Adiantum Capillis veneris Mount 

 Sinai ; Dactylis glomerata ; Avena Sativa Desert of Sinai ; Poa 

 littoralis El Tor; Care^ j^amcea Mount Sinai ; Char a Vulgaris 

 Bethlehem ; Typha angustifolia, El Tor and Mount Sinai ; Ana- 

 gallis arvensis Mount Sinai ; Veronica anagallis Do ; Cuscuta 

 eptfthimum Do ; Tragopogon major, Sonchus oleraceus Desert 

 of Sinai. 



VI. — Chloride of Gold as a Caustic, 



M. Recamibr has employed this substance dissolved in aqua regia, 

 in the proportion of 1 ounce of the latter to 6 grains of the chloride, 

 with great success in cancerous affections. A little lint is dipped in the 

 solution, and the diseased part is then to be rubbed with it ; and the 

 effect carried to a considerable depth, so as to produce an eschar which 

 separates in the course of three or four days. The application is to 

 be repeated six or eight times, according to the extent of the ulcerated 

 surface. Little pain accompanies its use. A case of cancer of the 

 neck of the uterus was successfully treated with this caustic, in the 

 Hotel Dieu. — (Journ. de Chim, Medic, i. 533.) 



VII. — Ink permanent in the Air. 



M. Braconnot, of Nancy, has published a recipe for ink, which he 

 says answers extremely well in Botanic gardens, and open or wet 

 situations, where names are required to be preserved permanently. 

 Take of Verdigris 1 part 



Sal ammoniac 1 part 



Soot i part 



Water 10 parts 



Mix the powders in a glass or porcelain mortar, adding at first one 

 part of water, in order to mix them well, then add the remainder of the 

 water. Shake the ink well from time to time. When it is to be 

 used, we must write with it upon a plate of zinc, and after some days, 

 it becomes hard, and cannot be obliterated by atmospherical influence 

 or by rubbing. The ink may be tinged with any colour, by substi- 

 tuting for the soot some mineral colouring matter. — (Ann. de Chim, 

 i, 319.)
