General view of page 12 of the album dealing with amyotrophic lateral sclerosis. Three drawings are pasted on a grey (faded green) cardboard (arrows). They show sections of the central nervous system (at the top) and of the adductor pollicis (at the bottom). In the lower right corner of the card, “Cas de Trouillet” (Trouillet’s case) can be read. An additional drawing on the right illustrates two microscopic aspects of an “altered slender column [of the spinal cord]”.
