Euc, Vol. II., p. 142) in associatiou witii E. fasciculosa 

 (see also Proc. Linn. Soc, N.S.W., 1901, p. 126). The 

 kino of E. intertexta, however, is closely allied to those of 

 the " ironbarks," or, perhaps, more nearly to that of E. 

 saligna, and falls into Class IV., while that of E. fasciculosa 

 falls into Class II., and is thus not in the same group. This 

 appears to be an analogous case with that of the kinos of 

 E. leucoxylon (Group II). and of E. sideroxylon (Group IV.), 

 in which species the botanicol features also show strong 

 resemblances. 



The Museum sample of kino of E. fasciculosa was pre- 

 sented by the late B iro i von Mueller, and c-ime from 

 Spencer's Grulf, South Australia ; that of E. intertexta was 

 sent by the Museum Collector. 

 (6) Eucalyplus kinos are practically constant in constituents 

 for each species, no matter where the trees arc grown, or 

 whether exuded from cultivated or from naturally grown 

 trees, and numerous instances of this fact have accmiiulated. 



(c) Chemical agreement between the kino and the oil of the same 



species is distinctly shown in many instances, although 

 the influences which directed the alteration in oil consti- 

 tuents are not always indicated in a parallel direction with 

 the kinos, and there are anomalies which at present are 

 not understood. Considered broadly, however, the exuda- 

 tions of species whose oils consist largely of terpenes, gene- 

 rally phellandrene, belong mostly to Class I., and only a 

 very few have been found to contain pinene in excess 

 instead of phellandrene, as for instance E. Wilkinsoniana, 

 E. dextropinea, E. laevopinea, and a few others. The kinos 

 of the second class and those of the intermediirte group 

 with the lower astringency are mostly obtained from species 

 the oils of which contain pinene and eucalyptol in some 

 quantity, and they usually show an absence of phellandrene, 

 or this constituent is only present in traces. The difficulty 

 experienced in the arrangement of the kinos of the inter- 

 r. ediate species, in order of sequence, may be largely due 

 to the greater exactness by which the oil constituents can 

 be determined, than is, as yet, possible with those of the 

 kinos, 



(d) Tlie results so far obtained with eucalyptus kinos show 



them to indicate evolutionary formation of the species, 

 and this may be traced through the exudations of the 

 Angophoras. The kinos of the Angophoras agree in 

 reactions with the exudations of those eucalyptus species 

 which in other directions show strong affinity between
