Palmam qui meruit ferat. Referring to the article on this subject (NATURE, vol. xii. p. 289), allow us, as the publishers of the botanical portion, to say that the indefatigable labours of Dr. Hooker, aided by the Government grant, resulted in six vols. 4to.; not two, as stated by the reviewer. This was published in three divisions, viz.: 1. Flora Antarctica, 2 vols.; 2. Flora Novæ Zealandæ, 2 vols.; 3. Flora Tasmaniæ, 2 vols.; the whole comprising nearly 600 coloured plates.
