Archibald Menzies, Surgeon Botanist

Archibald Menzies, the 2nd son of a Highland gardener, was born in 1754. His father was the head gardener at Castle Menzies near Loch Tay, and the clan leader's distant relative. From him Archibald learnt respect for authority and the joy of growing things. In an atmosphere of secure prosperity young Archibald had a good practical and general education, working in the Castle gardens and grounds...

Generalized Douglas-Weyl Finsler Metrics

In this paper, we study generalized Douglas-Weyl Finsler metrics. We find some conditions under which the class of generalized Douglas-Weyl (&alpha, &beta)-metric with vanishing S-curvature reduce to the class of Berwald metrics.

Observations on the Biology of the Lousefish, Phtheirichthys lineatus (Menzies)

THE LOUSEFISH, Phtheirichthys lineatus (Menzies) , is a slender member of the Echeneidae which is often free-swimming but which also attaches to immotile objects or slow-swimming fishes. It is pantropical, uncommon, and little known biologically. This paper reports on 24 lousefish in the collections of the Bureau of Commercial Fisheries Biological Laboratory in Honolulu. Capture data for these ...

On Special Generalized Douglas-Weyl Metrics

In this paper, we study a special class of generalized Douglas-Weyl metrics whose Douglas curvature is constant along any Finslerian geodesic. We prove that for every Landsberg metric in this class of Finsler metrics, ? = 0 if and only if H = 0. Then we show that every Finsler metric of non-zero isotropic flag curvature in this class of metrics is a Riemannian if and only if ? = 0.
