Hence we ought not to expect at the present time to meet with numerous transitional varieties in each region, though they must have existed there, and may be embedded there in a fossil condition. But in the intermediate region, having intermediate conditions of life, why do we not now find closely-linking intermediate varieties? This difficulty for a long time quite confounded me.
In two minutes another quoit clattered under his chair, this he likewise returned very politely; at the third, however, he sighed and gave up his study of the blue and sauntered aft to the smoking-room such is life on a P. & O. The above picture is intended to represent ladies in afternoon dress, the colours of the intermediate tints of the rainbow expressions celestial.
To these were added the forces of the more or less dependent tribes of Libya and Spain and the famous slingers of the Baleares, who seem to have held an intermediate position between allied contingents and mercenary troops; and finally, in case of need, the hired soldiery enlisted abroad.
There he learned that there was a ship at the leeward, about to sail for Boston; and, taking passage in the Pilgrim, which was then at Monterey, he came slowly down, visiting the intermediate ports, and examining the trees, plants, earths, birds, etc., and joined us at San Diego shortly before we sailed.
If the mechanical properties of the bodies intermediate between solids and liquids have only lately been the object of systematic studies, admittedly solid substances have been studied for a long time. Yet, notwithstanding the abundance of researches published on elasticity by theorists and experimenters, numerous questions with regard to them still remain in suspense.
A sensation fades gradually, passing by continuous gradations to the status of an image. This retention of the immediate past in a condition intermediate between sensation and image may be called "immediate memory." Everything belonging to it is included with sensation in what is called the "specious present."
By its aid it crawls, leaps, and burrows in the sand, where it lies drinking in the salt water through one of its siphons, and discharging it again through the other. Put the shell into a rock pool, or a basin of water, and you will see the siphons clearly. The valves gape apart some three-quarters of an inch. The semi-pellucid orange "mantle" fills the intermediate space.
Naturalists, for instance, would be forced to acknowledge that the only distinction between species and well-marked varieties is that the latter are known or believed to be connected at the present day by intermediate gradations, whereas species were formerly, though they are not now, thus connected.
This could be effected only by the future geologist discovering in a fossil state numerous intermediate gradations; and such success seems to me improbable in the highest degree.
A straight line would result if both pendulums were released at the same time, a circle, if one were released when the other had half finished a swing, and the intermediate ellipses would be produced by various alterations of "phase," or time of the commencement of the swing of one pendulum relatively to the commencement of the swing of the other.
