Mr Dugald Macfarlane.— It will be remembered that on the last anniversary of the Battle of Waterloo, occasion was taken to present Mr Dugald Macfarlane, one of the few remaining survivors of the Battle of Waterloo, with a birthday testimonial of considerable value. It may not be generally known, however, that Mr Macfarlane has since received a letter from the president of the mess of the Rifle Brigade, with which regiment he was so honorably connected, containing a request that the mess might be furnished with a portrait of the veteran. Mr Macfarlane at once consented, and an admirable photograph of him was taken by Messrs Dosseter [sic] and Co., and forwarded by the last Californian mail to Gibraltar, where the Brigade is stationed.

In the next number of the New Zealand Country Journal, issued under the auspices of the Canterbury Agricultural and Pastoral Association, will appear an interesting sketch of the Moriori race — a race almost extinct, and confined to the Chatham Islands, together with a photograph of one of these peculiar people. The sketch is written by Mr Potts, of Governor's Bay, who recently met with a Moriori, and persuaded him to allow, himself to be photographed by Mr Dossiter [sic], of this city [Christchurch]. The photograph in question presents a splendidly made man of about 50 years of age, with very little appearance of the Maori in his features except that he is slightly tattooed.

The November number of the “New Zealand Country Journal,” of which we have received a copy, presents features of more than ordinary interest. The opening paper, which forms a valuable ethnographical contribution, is one that would scarcely have been anticipated in a journal, professedly devoted to agriculture. It will, however, be heartily welcomed by a large, circle of readers, who cannot fail to be deeply, interested in the account which Mr Potts has, given of the decaying race of Morioris. They will, moreover, fully sympathise with him in his expression of opinion that "If a history of the Maoris is considered to have no claim on the care of Government, at least it is a subject which is worthy of the consideration and support of the various Philosophical Societies and Institutions that have been founded for the purpose of promoting the study and cultivation of several departments of science, and philosophy.”
The paper is illustrated by an admirably executed photographic portrait of a Moriori, who acceded to the request of Mr Potts, “that he would discard for awhile a portion of his raiment, whilst undergoing photographic treatment;” Mr Potts considering that “the aspect of his natural covering would be of more interest than the portraiture of even the best effects of tailor’s art." Looking at this portrait, it is not easy to believe in Blumenbach’s sweeping theory, that all the Islanders and tribes in the Southern Ocean are one distinct variety or species of the human race. Mr Potts also contributes another of his pleasantly chatty papers in the series of “Out in the Open,” and on this occasion he has a great deal to say about the New Zealand kingfishers...

Original Inhabitants of the Chathams.
The scientific expedition to the Chatham Islands, undertaken by the Philosophical Institute of Otago, may probably obtain further information regarding the original inhabitants of the islands, the Morioris. This possibility gives renewed interest to an article “Meeting with a Morioris,” which was contributed by Mr. T. H. Potts, to the New Zealand Country Journal, dated November 1, 1879. The New Zealand Country Journal was published by the Canterbury Agricultural, and Pastoral Association, and its contents were not rigidly confined to articles on farming subjects.
To Mr. Potts’ article is prefixed a photograph (not a reproduction of a photograph) of the Moriori he met; the photograph is still pretty clear; it was taken (as the text informs the reader) by E. Dossetter, Christchurch, New Zealand, January, 1879. Mr. Potts describes how he fell in with a small party of Maoris at Lyttelton and noticed amongst them a man whose features offered such a marked contrast to those of his companions that his curiosity was aroused. Inquiry elicited the information that the man was a Moriori on the eve of return to his island home.
“The Moriori,” Mr. Potts wrote, “was robust in figure, tall of stature, not darker in colour, perhaps, than many a Maori, but of a dull dusky hue, rather than of the rich brown that distinguishes, the great proportion of the Natives of New Zealand. The brows were prominent, the eyes of an almond or elliptical shape, whilst the somewhat fleshy nose curved with a fullness of form that is characteristic of the Jewish people. A full-face view was especially favourable for noticing the look of the eyes, which showed a contemplative watchfulness; it may be thought fanciful but their usual, or settled expression conveyed the idea that they were patiently waiting for what was to happen; as they might have belonged to some animal which, though not yet attacked, was preparing, or prepared, for defence.
This quiet individual of stolid demeanour proved an excellent sitter before the camera, and some good negatives were successfully taken, from one of which was printed the photograph which appears with this brief notice. We thus possess an excellent likeness, a faithful record of the outer man, a fair type of the doomed Moriori.
"During a visit to Christchurch, in a quiet, undemonstrative way, he appeared much interested in the larger buildings of the town: the traffic of the streets he watched with some surprise. He seemed acquainted with the names of several of the natural features of Banks Peninsula, such as mountains, headlands, etc. —information which, by oral tradition, must have descended with the teaching of many generations. Some of the Raupaki [Rapaki] Natives say that Morioris are descended from natives of this part of New Zealand, a few of their people forming a settlement in Chatham, Island"...

Timoti Tara (also known as Karaka and Pawa Ngamunga Kahuki). He was one of the signatories of the 1862 petition to the New Zealand Government and was a Moriori claimant to the 1870 land court [identified by Susan Thorpe, Hokotehi Moriori Trust, 2020].
