DR. ANGUS SMITH ON PEAT. 303 



the bog of Allen — first red, then brown, and lowest black. 

 In the same volume of Crell, G. G. Ten Haaff explains how 

 he found sal ammoniac sublimed from peat. 



Du Menil, in TrommsdorfFs l Journal ' for 1826, gives 

 only 0*36 p. c. soluble in ether and 075 in alcohol. This 

 is from what he calls Baggertorf from the Steinhuder 

 Meer in Hanover. 



In 1 8 1 o ? in a paper by Du Menil, there is this sentence : — 

 u Peat must be able to grow under water, as the follow- 

 ing passage from Schooclr's works show : — c Amplius saepe 

 usu venit, ut turfofodinse se demum prodant subductione 

 aquarum, bituminosique cespites ibi effodiantur, ubi antea 

 navigabatur aut aquae stabant/ Mart. Schoockii, Tract, 

 de Turns. Groning. 1658, p. 29." — Trommsdorff's Jour- 

 nal de Pharmacie, vol. xix. p. 2, 1810. Here the filling-up 

 of great spaces by the growing of peat is clearly observed 

 and expressed. 



Du Menil gives the names of many plants found in 

 the peat, and mentions Papier torf, Sumpftorf, and Moor or 

 Modererde, and Torfruss or the soot from peat, which, he 

 says, contains sulphate of ammonia, which is used for the 

 formation of sal ammoniac and sulphur. 



The Germans have many names for the various peats 

 and their products (asphalt, resin, and wax) — Rasentorf, 

 Pechtorf, Moostorf, Heidetorf, Schilf- oder Rohrtorf, Holz- 

 torf, Meer- oder Tangtorf, Sumpf- oder Baggertorf, Moder- 

 torf and Streichtorf, Maschinentorf, and Presstorf, Wurzel- 

 torf, Erdtorf. Then they have Hochmoore, Kesselmoore, 

 Wiesenmoore, and Meermoore. 



Hiinefeld speaks (in Erdmamr's 'Journal' of 1838, 

 vol. iii. p. 456) of bread-shaped masses which contain resin 

 to the extent of 16*8 p. c, the resin being formed in the 

 course of 800 years from bread which had fallen into the 

 moss.
