Commemorated in Google today as it was his birthday. Fantastic wildlife illustrator. Found this great quote about him...
The botanist Sir William Jackson Hooker, wrote of this as: "In my life I
think I never read such a series of trash and nonsense. There is a man
who left this country with the character of a first rate naturalist
(though with many eccentricities) and of a very first-rate Natural
History artist and he goes to Australia and takes up the subject of
Botany, of which he is as ignorant as a goose."
I like the last part especially. Feels familiar.
