 ... more thoughtful of men did not fail to observe, and never forgot, that no ship could possibly depart from, or arrive at Europe, without passing within range of some one of the islands' guns. A row of eight lay an irregular crescent (its convexity facing Europe) from just outside the Straits of Gibraltar, where O'Hara admiraled the Mahomet, to the 55th of latitude, where the Goethe lay on the Quebec-Glasgow route: these commanding the European trade with the States ...

The ice filling an immense basin, several miles broad and long, formed a low dome,* [This convexity of the ice is particularly alluded to by Forbes ("Travels in the Alps," p.386), as the "renflement" of Rendu and "surface bombee" of Agassiz, and is attributed to the effects of hydrostatic pressure tending ...

... and as it also has topographical relations with the mouth, it has been designated in English by the non-committal term stomochord. It is not a simple diverticulum of the collar-gut, but a complex structure possessing paired lateral pouches and a ventral convexity (ventral caecum) which rests in a concavity at the front end of the body of the nuchal skeleton (fig. 3). In some species (Spengelidae) there is a long capillary vermiform extension of the stomochord ...

It was made of two parts, a broad piece of bamboo with a longitudinal slit at one end and a thin narrow piece of the same material, the reed, which was held firmly against the fenestra on the concave side of part number one. The convexity of the instrument was pressed against the lips and the sound was produced by projecting the breath through the slit in a speaking or singing tone in such a way as to cause vibrations in the reed.

Observe, also, that it is constantly found, that so far from there being a concavity in the interior surface of the cranium answering to the convexity apparent on the exterior—the interior is convex too. Dr. Baillie thought there was something in the system, because the notion of the brain being an extendible net helped to explain those cases where the intellect ...

Crevasses are opened on lines at right angles to the direction of the tension. TRANSVERSE CREVASSES are due to a convexity in the bed which stretches the ice lengthwise (Fig. 99). MARGINAL CREVASSES are directed upstream and inwards; RADIAL CREVASSES are found where the ice stream deploys from some narrow valley and spreads upon some more open space. What is the direction of the tension which causes each ...
