    A selection of human photomicrographs captured by Arthur E Smith in 1904 using his early apparatus:

    Figure 50: human lung tissue showing sectioned bronchiole

    Figure 51: human blood showing erythrocytes (red blood cells)

    Figure 52: a sagittal section of a molar, showing internal cavity and roots

    Arthur E Smith focuses images on his early apparatus for photomicrography.

    Simply obtained by photographing images upon the microscope’s eyepiece, the images produced became the focal point (pun not intended) of the 1909 book Nature through Microscope & Camera by Richard Kerr.

    A false-colour scanning electron micrograph of phagocytosis in progress.

    Phagocytosis (translating rather wonderfully to ‘devouring cell process’) is the system by which this macrophage (red) is able to engulf and thereafter destroy Mycobacterium tuberculosis (yellow) as well as other threats to your body’s health. 

    Macrophages, after engulfing the offending entity, drag it forcibly into a specially formed compartment within the cell. Inside, they are subjected to a formidable array of chemical attacks that render the target dead within minutes.

    This is Pismis 24-1 (HDE 319718), a region with spectacular diversity, beginning with its open cluster of neighboring stars, called Pismis 24. Together, they are centrally located within the diffuse nebula NGC 6357, which is located approximately 8,150 light-years from Earth in the constellation of Scorpius.

    Persistent pupillary membrane (PPM) is a condition of the eye involving remnants of a fetal membrane that persist as strands of tissue crossing the pupil. The pupillary membrane in mammals exists in the fetus as a source of blood supply for the lens. It normally atrophies from the time of birth to the age of four to eight weeks. PPM occurs when this atrophy is incomplete. It generally does not cause any symptoms. The strands can connect to the cornea or lens, but most commonly to other parts of the iris.

    Note the ‘cut-off’ edge of the needle which gives its point an asymmetrical tip; a sharper piercing edge than if it were purely elliptical.
