About ten o'clock
At a quarter after three o'clock on Sunday morning , February 12 , Kant stretched himself out as if taking a position for his final act , and settled into the precise posture which he preserved to the moment of death . The pulse was now no longer perceptible to the touch in his hands , feet or neck . I tried every part where a pulse beats , and found none anywhere but in the left hip , where it beat with violence , but often intermitted . About ten o'clock in the forenoon he suffered a remarkable change ; his eye was rigid and his face and lips became discolored by a cadaverous pallor . Still , such was the effect of his previous habits , that no trace appeared of the cold sweat which naturally accompanies the last mortal agony . It was near eleven o'clock when the moment of dissolution approached . His sister was standing at the foot of the bed , his sister 's son at the head .
