Notes on some Tasmanian eucalypts

In "A Research on the Eucalypts of Tasmania and their Essential Oils," Messr's. Baker and Smith have made frequent reference to my work, and some observations are necessary. They have given undue prominence to a paper by me in these Proceedings for 1902, sometimes ignoring that in two of my works (Critical Revision of the Genus Eucalyptus and Forest Flora of New South Wales) additional knowledge has enabled me to modify opinions in the earlier paper considerably. I emphasise the point that an author can claim to be judged by his latest utterance on a given subject.<br>The store of laboriously acquired details, as incorporated in the above works, has brought difficultly accessible descriptions and specimens under the notice of those interested, and it would be well if my readers would make it their business to directly consult the evidence in regard to Tasmanian species thus brought together.<br>The paper of the joint authors to which I have referred owes much of its value to determinations of the composition of various oils ; further, there is much reference to determinations of species on grounds which have no direct reference to those substances. It will be desirable to investigate some of the principles which underlie the relations of essential oils and the species which yield them.
