0 a glass container filled with sand that takes one hour to move from an upper to a lower part through a narrow opening in the middle, used especially in the past to measure time -- （用于计时的）沙漏
The sands are running out in the hourglass so far as they are concerned.
Compound eyes in untreated specimens are reddish and somewhat hourglass-shaped, concave on the anterior and posterior edges, not divided.
Non-image incensario forms are primarily open bowls (lak?) or basins and pedestal or hourglass (biconical) vase shapes.
During growth there is also a change from an 'hourglass-shaped' glabella to a nearly parallel-sided glabella, tapering slightly forward.
The timepiece in question seems to have relied upon the movement of a fluid, something like sand in an hourglass.
The hourglass visualises this fragmentation of time through the falling of sand grains.
The transverse view clearly shows an hourglass shape to the imploded target.
The transverse views demonstrate an hourglass-shape to the imploded target.
