The inference that can be drawn from this excerpt from Jane Austen's Pride and Prejudice is that Mr. Bennet's property is entailed, meaning it is passed down to male heirs in the family. This situation poses a challenge for his daughters as they will not inherit the estate directly. Additionally, the mention of their mother's fortune being insufficient to make up for the lack of inheritance from Mr. Bennet's estate highlights the financial constraints and social dynamics within the family. The background information about the father being an attorney in Meryton and leaving a sum of four thousand pounds further adds context to the family's financial situation and social standing.
