These fishes have the peculiar habit of adhering to the vertical surfaces of sides of aquaria, even the smooth surfaces of slate or glass. In nature they are taken occasionally on gravelly or sandy ground, but probably live also among rocks and adhere to them in the same way as to vertical surfaces in captivity. Mar. Biol.
It has long been known that altitude increases the heart rate and tends to lower the systolic and diastolic blood pressures; that these conditions, though actively present at first, gradually return to normal, and that after a prolonged stay at the altitude may become nearly normal for the individual.

This work contains transverse and longitudinal sections of one hundred Japanese woods, and numbers 45 and 46 represent Z. acuminata. It would be worth the while of those who are interested in the introduction and cultivation of timber trees in temperate climates to procure Kinch's handbook. IDENTIFICATION. Zelkova acuminata, D.C. Prodr., xvii., 166; Z. Keaki, Maxim. Mel. biol. vol. ix, p. 21.
The version followed on the present occasion was republished in old English, in 1811, in an appendix to a reprint of HAKLUYT'S EARLY VOYAGES, TRAVELS, AND DISCOVERIES; from which we learn that it was translated from Latine into Englishe, by Richarde Eden, and originally published in 1576. In both these English versions, the author is named Lewes Vertomannus; but we learn from the Biol.
There is, however, one scale-character among the Pleuronectidae which appears to stand in direct contradiction to the conclusions drawn by me concerning scales in general. It not only develops by a gradual change, but it is a secondary sexual character developing in the males only at maturity. Mar. Biol. Assn., vol iii.
