Mr. Marsh was in a coma and attached to life support machines.
He's alive, but he's been in a coma for a week.
(2) The condition for freedom from coma in the third order is also of importance for telescope objectives; it is known as " Fraunhofer's condition."
I read that when people wake up from a coma, it's always gradual.
These anastigmatic lenses, which are manufactured up to X 40, are chromatically and spherically corrected, and for a middle diaphragm the errors of lateral pencils, distortion, astigmatism and coma are eliminated.
