This is a hint for the game Raving Manor. Please be warned, the following hint gives information that could be considered a spoiler. For this reason, we would like to caution you about reading the hint unless you are certain that you want to proceed with knowing the information contained herein.
So, you have found a wax cylinder that apparently the doctor had in his possession, and you are not sure what to do with it. Given the era of the events at Raving Manor, wax cylinders were not uncommon for audio recordings. The recordings could be played back using a gramophone, a device that could be described as a wind up record player.
In your exploration of the Manor you probably have come across a gramophone. So now all you have to do is to dance over to it and play the recording. Of course, I would wager that it is not a very well produced recording, since the doctor may have been a bit rushed at the time, definitely under a bit of stress. You could even say that he was sick to death, perhaps...
