522 TRANSACTIOXS AND PROCEEDINGS OF THE [Sess. LX. 



Another from the same kind donor has taken its place — 

 planted 1895. "This and the following yield much more 

 eucalypt oils, than any other species." — Mueller. 



XII. Eucalyptus regnaxs (Giant Gum). 



1. Cromla, Corrie. Planted 1872. (^rew for ten years. 

 Was killed by being transplanted. 



2. Cromla, Corrie. Planted 1892. In autumn of 1894 

 its height was 10 feet 5 inches. Cut to the ground. 



This is the tallest tree in the world, one having been 

 measured -115 feet in height. Regarding it and E. aniyg- 

 dalina Baron von Mueller writes : " Fresh branchlets of 

 eucalypts, and specially of these species, should be placed 

 daily in the bedrooms of phthisic patients, best under the 

 bedstead, the effect being not only antiseptic, but also 

 sedative, and to some extent hypnotic. The fresh leaves 

 also purify the air of hospitals and unsalubrious dwellings. 

 All eucalypts with strong-scented foliage are useful also 

 as insecticides. By planting eucalypts parts of Piome, 

 previously unhealthy, have been rendered most healthy.'"' 



XIII. Eucalyptus polyanthema (Picd Box Tree). 

 Cromla, Corrie. Planted 1886. Died 1892. 



"This tree grows to the height of 150 feet. Its wood 

 is only exceeded in transverse strength by the two ironbarks 

 (E. k'Moxylon and E. dderophloia). It differs from most 

 eucalypts in the broad poplar shape of its leaf." — Mueller. 



At Cromla it throve, but died without apparent cause. 

 On examination the roots were found to be decayed. In 

 Australia it grows on dry ridges and hills. The soil at 

 Oomla though well drained, may have been too cold and 

 wet. It was a beautiful tree. " It is more hardy than 

 E. glohulus." — Xaudin. 



XIV. Eucalyptus alpin'a (Alpine Gum). 



1. Corrie Hotel, Planted 1884, when 2 feet in height. 

 1894 — height, 16 feet 2 inches; girth, 1 foot. Killed. 



2. Strabane, Brodick. Planted 18S6. Killed. 



This eucalypt is remarkable, first, for its limited natural 

 habitat, being confined to the summit of Mount William 

 (5600 feet, latitude o7'), the highest of the Grampian 

 range, fifty miles north of ^Melbourne ; second, for its bushy 

 habit : third, as growing with much greater luxuriance 

 in Arran than at Melbourne, Australia. At the Botanic
