be closely related to an oil from Palestine examined by us on a 

 previous occasion 1 ), but unfortunately we were unable to ascertain 

 from which species the previously examined sample had been distilled. 



On the strength of our previous examination 2 ) we had stated 

 that in an oil of Salvia officinalis L., of Dalmatian origin, no camphor, 

 but only borneol was present. Now we recently availed ourselves of 

 a further opportunity of examining a Dalmatian oil which had been 

 supplied to us, the constants of which were as follows: d^o 0,9282; 

 «d -\- lo° 2'; acid no. 1,8; ester no. 12,6; ester no. after acetylation 52,1, 

 corresponding to 14,8 °/ borneol; soluble in 8 and more vol. 70 per cent, 

 alcohol, soluble in 0,8 and more vol. 80 per cent, alcohol. On fractional 

 distillation 72,6 °/ of the oil passed over at 40 to 7 6° (6 mm. pressure); 

 this consisted of pinene, cineol and thujone fractions; next followed a 

 fraction from 76 to 9 2°, which represented i5,4°/ of the oil, and 

 solidified on cooling; it contained, besides borneol, chiefly d-camphor, 

 which was identified by the melting point of the oxime (11 8°). The 

 distillation-residue amounted to i2°/ . 



In consequence of this result, which took us quite by surprise, we 

 also examined in this respect sage oils distilled by ourselves from the 

 Dalmatian herb. 



Normal oil: diso 0,9209; «d -|-4 2'; acid no. 1,4; ester no. 9,3; 

 ester no. after acetylation 43,3, corresponding to i2,3°/ borneol; 

 soluble in about 12 vol. 70 per cent, alcohol; soluble in 1 and more 

 vol. 80 per cent, alcohol. On fractionating in vacuo (3 mm. pressure), 

 73,4 °/ passed over from 40 to 65 ; 7,5% ^ rom 6.5 to 8o°, and 

 1 o °/o from 80 to 1 20 , whilst 9, 1 °/ remained behind in the residue. But in 

 this case we were unable to separate camphor out of any of the fractions 

 coming under consideration, not even by cooling in a freezing mixture. 



Quite different, however, was the behaviour of the oil obtained 

 by cohobation from the distillation waters; this contains the portions 

 of the normal distillate which are readily soluble and suspended in 

 water, and forms a part of the above normal oil. We call it 



Water oil: d 15 o 0,9503; « I) -(-io 25 / ; soluble in 2,5 and more 

 vol. 70 per cent, alcohol; soluble in 1,3 and more vol. 80 per cent, 

 alcohol. In the distillation in vacuo (3 mm. pressure) there passed 

 over 14,4% fr° m 4° to 6o°; 25% from 60 to 65 ; 2j,j°/ from 

 65 to 90 ; 17,9% from 90 to 123 ; residue 15%. From the fractions 

 which passed over from 60 to 90 , borneol (m. p. 203 ), and d-camphor 

 (m. p. of the oxime 1 1 8°) could be separated off. The portions which 

 passed over last on distilling the leaves, i. e. the
