“[Charles] has received 30 pounds for his share of the privateer & expects 10 pounds more–but of what avail is it to take prizes if he lays out the produce in presents to his Sisters. He has been buying Gold chains & Topaze Crosses for us;–he must be well scolded.”
letter to Cassandra
May 27, 1801 
Jane’s younger brother Charles was in the navy (along with their brother Frank). You can see the topaz crosses Charles bought his sisters at Jane Austen’s House Museum.
