From one cord of "Western wood", Pritchard obtained 40 gallons of 

 a water-white turpentine oil, 1,5 gallons of a turpentine oil of second quality, 

 10,5 gallons light oil, 3,1 gallons light product (from heavy oil), 2,7 gallons 

 light product (from extra heavy oil), 87,5 gallons heavy oil, 40,6 gallons 

 extra heavy oil, 950 lbs. charcoal, and 138 lbs. residue. 



Oil from the turpentine of Abies cephalonica, Link. This tree, 

 which occurs on Mount Ainos in the Greek Island of Cephalonia, yields a 

 resin which is locally used as a popular remedy, being used both internally, 

 as an aperient, as well as externally in affections of the skin. J. Emmanuel 1 ) 

 has subjected this turpentine to closer examination. He describes it as a 

 greyish-yellow mass of the consistency of honey, with an agreeable turpen- 

 tine-like odour and a bitter and aromatic taste. Emmanuel has obtained from 

 the raw material, among other bodies, 17,4 p. c. of a colourless essential 

 oil which, at ordinary pressure, boiled between 89 and 175° and, at 15°, 

 had sp. gr. 0,9279. Its rotation was —68° in a 200 mm. tube 2 ), n D13 , 5 o 1,4745. 

 Emmanuel says nothing with regard to the constitution of the oil. 



K. Dieterich 3 ) has been offered by exporters, through a Hamburg firm, 

 a resin described by the sellers as Gummi Thus, which when carefully 

 tested, proved to be an American fir-resin. The product does not contain 

 gum, and is therefore no gum-resin, as might be assumed from the name. 

 It yielded from 9 to 10 p. c. oil of which the constants agreed with tur- 

 pentine oil (b. p. about 155°; d 18)5 o 0,8667; a moo + 13,35°; n D 1,47644). 



Larch turpentine oil. Our efforts, extenting over several years, 

 to procure authentic raw material for the distillation of larch turpentine 

 oil have at last been crowned with success by the receipt, from an 

 entirely reliable source, of a sufficient quantity of larch turpentine. This 

 turpentine, after being filtered, was clear, of a faint yellow colour, and of 

 a consistency just above the verge of liquescence. Its constants were 

 as follow: « D + 29°20'; acid v. 69,5; ester v. 55,9; giving a clear solution 

 with 3 parts of 80 p. c. alcohol, wholly soluble in light petroleum except 

 for a few flakes. We obtained from it by steam distillation 13,5 p. c. of 

 |kn oil possessing the following characters: di 5 o 0,8649, « D — 8° 15', n D20 o 

 1,46924, acid v. 0, ester v. 5,9, soluble in 6 volumes and more of 90 p. c. 

 alcohol. Behaviour on boiling in a Ladenburg flask (753 mm.) 157 to 161° 

 60 p. c, 161 to 164° 20 p. c, 164 to 168° 6 p. c, residue 14 p. c.

2 ) Emmanuel's statement is not quite clear. He writes: „The polarisation was —68° in a 

 200 cm.-Tube Eh. according to Wild". We assume that our reading of this statement is correct.
