Both Quote by August Krogh
“I found it possible to observe at least the superficial capillaries of muscles both in the frog and in mammals through a binocular microscope, using strong reflected light as a source of illumination. Resting muscles observed in this way are usually quite pale, and the microscope reveals only a few capillaries at fairly regular intervals.”

Source Scientific Article: Observation of Muscle Capillaries, 1900s
He describes using reflected light microscopy to view superficial capillaries in frog and mammal muscles, noting their pale appearance and regular spacing.
In simple terms: Microscope can show muscle capillaries with reflected light.
