A more thorough explanation:

A natural object is a person who is likely to receive a portion of someone's estate based on their relationship with that person. This is also known as a natural object of bounty or testator's bounty.

For example, if a person writes a will and leaves a portion of their estate to their child, that child is a natural object of the parent's bounty. Similarly, if a person leaves a portion of their estate to their spouse, the spouse is a natural object of the testator's bounty.

These examples illustrate how a natural object is someone who is expected to receive a portion of an estate based on their relationship with the person who wrote the will. It is important to note that the term "natural object" is typically used in the context of wills and estates.
