Final answer:
The text describes an event on a ship for a Sailors' Orphanage, but does not specify the kind of party the Admiral and his ex-wife are attending. The main focus is on Mrs. Ebbling's interaction with her ex-husband during the event.
Step-by-step explanation:
The provided text does not explicitly mention the kind of party the Admiral throws with his ex-wife. Instead, it details an event that took place on a ship where there was a concert organized for the benefit of a Sailors' Orphanage. During this event, Mrs. Ebbling, the Admiral's ex-wife, attended dinner for the first time since embarking on the ship and sat with her husband.
She faced some difficulty with her cloak due to the wind, which her husband failed to notice as he was preoccupied with helping another guest. It seems that the focus of this passage is more on the personal dynamics between the characters rather than on a specific type of party.
