Smell receptor. Colored transmission electron micrograph (TEM) of a section through the olfactory (smell) epithelium of the nose. At center (orange) is an olfactory receptor cell body. At its top two long, modified non-motile cilia project into the liquid lining of the nasal cavity. The cilia are thought to be the sites of interaction between odoriferous substances and the receptor cells. Surrounding the receptor cell are the supporting cells with surface microvilli (finger-like). Within the cells, mitochondria (purple) & endoplasmic reticulum (flattened sacs) are seen. Magnification: x2,130 at 6x7cm size. Magnification: x7,300 at 10x8 inch size.

“Sit down, my dear,” said Mr. Jarndyce. “This, you must know, is the growlery. When I am out of humour, I come and growl here.”
“You must be here very seldom, sir,” said I.
“Oh, you don’t know me!” he returned. “When I am deceived or disappointed in—the wind, and it’s easterly, I take refuge here. The growlery is the best-used room in the house….”
Bleak House, by Charles Dickens
Poet Laureate Alfred Lord Tennyson thought this picture of a rather sultry Alice disguised as a street urchin — hand-tinted by Carroll himself — the most beautiful photograph he had ever seen.
