I strongly agree that connecting these transformers in series is a 
bad idea. The INPUT voltage WILL divide between them, but there is 
no satisfactory neutral, and no satisfactory way to create a 
neutral, because they are AUTOTRANSFORMERS. 

Autotransformers ARE safe devices -- IF used properly. Proper means 
the entire winding connected between "hot" and "neutral," the load 
connected between the tap and neutral, and the green (safety ground) 
carried from source to load and connected to the transformer frame. 

The first question though is, "What are you trying to accomplish in 
the first place?" That is, what voltage do you need, and at what 
current?
