Abstract
THE reviewer of the above-named work (see NATURE, vol. iii., p. 210) describes the plates as inferior to those in the Synopsis. With this opinion I fancy many will differ; as correct representations of the species described, they are far in advance of those in the Synopsis, for example, compare the figure of Navicula tumens in the latter work with Navicula rostrata in Dr. Donkin's; with the exception of the outline, the figure in the Synopsis does not resemble that species, and is inferior to Ehrenberg's in the Microgeologie. Also compare N. Hebes, N. palpebralis, N. subsalina, N. latiuscula, N. alpina, with the corresponding forms in the Synopsis, and I think the superior fidelity of Dr. Donkin's illustrations will be conceded.
