TWO NEW SPECIES OF EUCALYPTUS. 457 
between 167 — 183°C. (cor.), this had specific gravity 0°9166 at 
15°C.; rotation a, 2°2°; refractive index 1°4668 at 20°C. Between 
183 — 250° C. 8 per cent. distilled; this had specific gravity 0°9359 
at 15° C.; rotation ay +0°6°; refractive index 1°476 at 20°C. It 
contained rather a large amount of eucalyptol, and gave the bromine 
reaction for the sesquiterpene, also the aldehyde reaction. Of the 
most closely allied oils it more nearly approaches £. dealbata than 
that of any other species which has yet been investigated, although 
the resemblance between it and the oil of #. Behriana, is also 
strongly marked. 
‘Being a Mallee, it was thought that it might contain a con- 
siderable amount of calcium oxalate in the bark. The green bark 
taken from small sticks, had a thickness of 1 to 2 millimetres; it 
was found to contain 3°85% of calcium oxalate. The amount of 
calcium oxalate in the bark of the largest piece having a diameter 
of 3 inches was 5°39 per cent. The crystals in the bark of this 
species differ in no respects from those of Eucalyptus barks gener- 
ally (see paper with plate by H. G. Smith. The amount of 
of lime in the bark of Z. dealbata was 1:19 per cent.” 
2. HUCALYPTUS MITCHELLI nN. sp.

quatuor mm. gemme vix tam longe quam calycistubus, racemus 
stellatus, pedunculum Jongum circiter unum mm.
