Date of Seniority Royal Navy 27 June 1832
James Wingate Johnston was born in Scotland c. 1804. He was a Graduate of the University of Glasgow
He first came to Australia as Assistant Surgeon on the Sulphur, arriving at Swan River, Western Australia on 6 June 1829. -
Three years later in correspondence to Governor Stirling dated 10 December 1832 from H.M.S. Suphur he gave his favourable opinion of the climate of Swan River . While on the Suphur a significant collection of plants, shells and minerals was made.
After a less than favourable report of the items taken back to England he made his feelings known:
Collections in Natural History brought home in H. M. S. Sulphur.........
In perusing your Journal for last month, I was not a little astonished at observing, under the head of Portsmouth correspondence, a paragraph alluding to the specimens brought home under my charge in his Majesty's ship Sulphur - Botany, conchology, mineralogy, and zoology, not particularly well preserved. I must beg leave to differ from your correspondent, with the exception of the zoological, which, from many of them having been nearly three years on board, and for four months previous to their being landed having been in the hold, may easily account to any nautical man or collector for their not being in the most perfect state; as for the mineralogical and conchological part, I am at a loss to comprehend what is meant; but as for the botanical, by far the most valuable part of the collection, I may safely say, that it was certainly in that state that any botanist could have arranged and classified it with ease. My own collection, a very minor one, which was preserved in the same manner, I presented to my esteemed friend and late preceptor Dr. Hooker, Professor of Botany, Glasgow, who expressed his high approbation both as to their state of preservation and value as rare plants.
Mr. Editor, I should not have troubled you with these remarks, but in justice I consider myself bound to relieve the character of my much-valued friend, Mr. Collie, the indefatigable collector and preserver, from this unfounded imputation.
Your most obedient servant,
J. WINGATE Johnston, M. D., Late Surgeon of H.M.S. Sulphur.
92, Renfield-street, Glasgow, 13th Feb. 1833
