this was less marked than with the oil of C. glauca. It was largely a terpene 

 oil, and, consequently, was not readily soluble in alcohol. Eventually it was 

 soluble in lo volumes of 90 per cent, alcohol. A small amount of resin deposited 

 on the sides of the bottle on keeping, although this deposit was in less amount 

 than with C. glauca. The oil contained about 12 per cent, of esters, of which half 

 was saponified in the cold with three hours contact. The alcohols present were 

 dextro-rotatory borneol and terpineol, and most probably geraniol. The alcohols 

 were present mostly in the form of esters. The acids separated from the esters were 

 acetic and butyric, the latter being most probably in combination with the terpineol. 

 Of all the species of Callitris investigated, this is the only one in which terpineol 

 was present in the oil in sufficient amount to be indicated with reasonable certainty, 

 and butyric acid was also present in greater quantity than in the oil of any other 

 species. The presence of a small amoimt of butyric acid has been detected in the 

 esters of several other species, and it may, therefore be, that terpinyl- 

 butyrate occurs in most of the oils of the Callitris in small amount, reaching a 

 maximum in the oil of this species. The results indicated that the predominant 

 limonene was the Iccvo-rotatory form, but the limonenes do not occur in this oil 

 in large amount ; the higher boiling fraction, being dextro-rotatory, indicated the 

 presence of the bornyl-acetate, which constituent is common to nearly all Callitris 

 species. The pinene fraction, was not so highly dextro-rotatory as with some 

 other species, thus indicating that the pinenes were present in these species in 

 the isomeric forms. A very small amount of a phenolic body was separated 

 but its distinctive characters was not determined, as sufficient material could not 

 be spared for the purpose. It may, perhaps, be allied to the phenol, callitrol, 

 isolated from Callitris timber, as in some directions it gave similar reactions. 



The specific gravity of the crude oil at yf° C. = 0-8683; rotation, Ad = 

 -\- 8-7°; refractive index at 20° C. = 1-4752. The saponification number was 

 34-64, equal to 12- 1 per cent, ester. In the cold, with three hours contact, the 

 saponification number was 17-85, equal to 6-25 per cent, ester. 



On redistilling, practically nothing came over below 155° C. Between 155° 

 and 167°, 54 per cent, distilled; between 167° and 174°, 20 per cent.; between 

 174° and 200°, 10 per cent. ; between 200° and 230°, 9 per cent. There was slight 

 decomposition of the esters at the higher temperatures. The specific gravity of 

 the first fraction at 20° C. = 0-8545; of the second 0-8534; of the third, 0-8674; 

 and of the fourth, 0^9422. The rotation of the first fraction Ad = +12-1°; of 

 the second, -|- 4-8°; of the third, — 2-5°; of the fourth, -|- 12-8°. The refractive 

 index of the first fraction at 20° C. = 1-4741. It had all the characteristics of 

 pinene. The nitrosochloride was readily prepared from it, and, when purified from 

 chloroform and methyl alcohol, melted at 107-108° C. The nitrosopinene prepared 

 from this, melted at 131-132° C. The saponification of the fourth fraction was 

 173-9, equal to 60-9 per cent, ester. The separated oil contained a considerable
