He is deadly pale: I fancy I can detect
traces of tears on his cheeks.
It is nowhere muddy, and a casual observer would say that there were no weeds at all in it; and of noticeable plants, except in the little meadows recently overflowed, which do not properly belong to it, a closer scrutiny does not detect a flag nor a bulrush, nor even a lily, yellow or white, but only a few small heart-leaves and potamogetons, and perhaps a water-target or two; all which however a bather might not perceive; and these plants are clean and bright like the element they grow in.
I have been surprised to detect encircling the pond, even where a thick wood has just been cut down on the shore, a narrow shelf-like path in the steep hillside, alternately rising and falling, approaching and receding from the water's edge, as old probably as the race of man here, worn by the feet of aboriginal hunters, and still from time to time unwittingly trodden by the present occupants of the land.
You may often detect a yet smoother and darker water, separated from the rest as if by an invisible cobweb, boom of the water nymphs, resting on it.
A moon so little less than full that the eye could barely detect
its slight tendency to become concave, shone serenely, creating a desirable combination of black shadows where the prowler might hide and great stretches of light in which the prowler might reveal his wickedness without disguise.

It was not easy to detect the real character of the trapper, through the mask which the hardships of so many years had laid upon his features, especially when aided by his wild and peculiar attire.
Intended as a research tool, the T790M quantitative mutation assay detects
the presence of a mutant thymidine base in a background of normal cytosine bases at position 2369 of the EGFR gene.
One of these centers detects
human antibodies to a particular bacterium or virus.
Wave pattern recognition technology in the sensor detects
highly reflective light, such as that off vehicles, and poorly reflective light, such as that off pedestrians.
In the steel cord reinforced radial tire industry, spacing faults are the most common detects
occurring in the production of steel cord reinforced ply.
We recover Propionibacterium acnes in patients with ear and eye infections only occasionally; DNA-based technology detects
it at least 50 times more often.
The detector is also combined with underground radar, which radiates two gigahertz of electromagnetic waves and detects
the reflection of landmines buried up to 80cm in the ground.
In general, choose the strongest, most sensitive detector you can afford, say detection experts, because it will more than pay for itself if it ever detects
a radioactive source.
