That which removes the Fore-Finger from the Thumb is known by the Name of Abductor, which arising out of the external and middle part of the Bone of the Elbow, and passing under the Annular Ligament, cleaves to the Lateral and outward part of the Bones of the Fore-Finger.
The Little-Finger hath two proper Muscles, viz. an Extensor and an Abductor.
The Extensor springs from the lower part of the Condylus of the Arm-Bone, and is fasten'd by a double Tendon in the second Articulation of the Little-Finger, and in the Tendon of the Extensor of all the others.
The Abductor, call'd also Hypothenar, hath its beginning in the small Bone of the Wrist, which is situated over the others, and is terminated in the first Bone of the Little-Finger on the outside.
