Description
This glass tube contains sterilized surgical silkworm gut sutures manufactured by J. F. Macfarlan & Co., Ltd. of Edinburgh and London. The label identifies the contents as “Macfarlan’s Sterilized Surgical Silkworm Gut”, consisting of 50 strands, each 12 inches long, marked White Fine, Size 2.
Silkworm gut sutures were produced from the processed silk glands of the silkworm and were widely used in surgery during the late nineteenth and early twentieth centuries. Unlike softer silk sutures, silkworm gut provided a strong, smooth, and relatively non-absorbable suture material, making it especially useful for skin closure and external surgical sutures.
The sutures are preserved in a narrow laboratory-style glass tube with a protective stopper and were originally packaged inside the labeled blue cardboard box. Medical supply companies such as Macfarlan produced sterile surgical materials that could be easily stored and distributed to hospitals and physicians.
Condition
Original glass tube containing bundled silkworm gut sutures tied with thread. Printed label remains clear and legible. White stopper intact. Original blue cardboard box present with visible handling wear and surface loss.

Historical context
Before modern synthetic sutures such as nylon and polypropylene became widely available in the mid-twentieth century, surgeons relied on natural materials including silk, catgut, and silkworm gut. Silkworm gut was valued for its strength and minimal tissue reaction when used for skin closure. Manufacturers sterilized and packaged the sutures in sealed tubes or envelopes to maintain surgical sterility prior to use.
Curious Facts, Ephemera, and Trivia
Despite the name, silkworm gut is not actually gut. It was produced from the silk glands of the silkworm before spinning occurred, processed into strong translucent filaments that resembled fishing line. The material was stiff and somewhat difficult to tie but provided excellent tensile strength and resistance to infection when used for external sutures.

Why it is in the Cabinet
Suture materials rarely survive in their original packaging, especially in intact glass tubes. This piece preserves not only the sutures themselves but also the way sterile surgical materials were packaged and distributed to physicians during the early twentieth century.
