Final answer:
A dactylogram is more commonly known as a fingerprint, which is a unique imprint from a finger used for identification, not to be confused with a manuscript, a hand-written document.
Step-by-step explanation:
The term dactylogram is more commonly referred to as a fingerprint. A dactylogram is an imprint taken from the pad of a finger that can be used for identification purposes because everyone's fingerprints are unique. This is distinct from a manuscript, which is a document written by hand, often with detailed decoration, and showcases the skill and consistency of scribes in historical contexts.
