    Description
    Study of crystals formed from a drop of urine, viewed by microscope, under magnification.

    Plate 15 from Amusement microscopique, tant pour l'esprit que pour les yeux, contenant... estampes... d'apres nature...by Martin Frobene Ledermuller, plates volume (Adam Wolfgang Winterschmidt, Nuremburg, 1764).

    Inscribed above: ‘TAB.XV.’

    The accompanying text is headed: ‘Table XV. Une Goute d’Urine.’ The author comments that: ‘Pendant que ces Cristaux se formoient, il sortit subitement des Extremités & du Bord de la Goute de longs Raions en forme de Scie & des Piques, qui à la Fin de la Configuration, étoient pleines d'Encoches des deux Cotés, comme on peut voir plus clairement.’ [While these crystals were forming, there suddenly appeared at the extremities and edges long blade-shaped saws and pikes, which at the end of each configuration, were serrated on both sides, as can be seen clearly].

    Martin Frobene [Frobenius] Ledermuller (1719-1769) German naturalist was employed in various capacities as a notary, turning to microscope studies after an illness induced temporary deafness.
