from ordinary distilled rose oil, and they puff up their oils as "oils 

 distilled by a special method". The abnormal pure rose oils are above 

 all characterised by a high content of phenyl ethyl alcohol, which is 

 obviously absent from the mixtures. According to Parry 's experience, 

 the ordinary Bulgarian rose oil has never a higher specific gravity than 

 0,855; it lies mostly between 0,850 and 853 (at 30 ). Oils with a 

 higher specific gravity which do not contain phenyl ethyl alcohol, 

 should unconditionally be rejected. Parry quotes the constants of 

 15 samples adulterated in the coarsest manner; the values lay 

 within the following limits: d 30 o 0,862 to 0,880; « D — 1° io' to — 3 20' '; 

 n D 1*4650 to 1,475; m - P- 2 ° t0 22 °- 



Rose Oil, German. The harvest in our Miltitz plantations, to 

 which we now as before devote our undivided attention (contrary to 

 the rumours spread from certain quarters), was this year at last again 

 carried on under very favourable weather-conditions, so that excellent 

 blossom - material could be worked up, and in point of quantity 

 also a result was obtained as had not been the case for years. 

 Several new plantations laid out during the last few years gave for 

 the first time a full yield, and the plants which had to be cut back 

 in 1904 owing to the drought, have meanwhile recovered completely. 

 On some days the fields afforded a quite imposing spectacle, and it 

 gives us particular pleasure to be able to state, that especially in this 

 year during the harvest time we had repeated opportunities of showing 

 this fine view to friends who took an interest in this cultivation. Our 

 new oil is of excellent quality, and we have also again at our disposal 

 abundant quantities of rose-pomade and rose-water.

Rosemary Oil. The French distillate can again, as in 1905, 

 be had very advantageously, but we are informed that the market 

 suffers much from the competition of Spanish rosemary oils, and that 

 as a consequence a number of manufacturers will no longer occupy 

 themselves with the distillation. In our opinion the value of the Spanish 

 quality is much overrated, for we have had before us a number of 

 samples which could not come under consideration as substitutes of 

 the French article, with regard to either their physical properties, or 

 their odour. In spite of the low prices of the last-named oil, the 

 Dalmatian producers still ride the high horse, and do not yet want 

 to hear of a reduction of their prices as compared with 1905. The 

 demand for their product is very brisk, which may be due to this, 

 that the light camphor oil, used in the preparation of the notorious
