Now me...

Though not the true purpose of your post, it brought a thought to 
me.  

Why doesn't Dolohov use the incantation for the "slashing 
movement/purple flame" spell?  The first time it is used (against 
Hermione) Dolohov has just been "Silencio-ed" by Hermione(Pg 792), so 
he obviously can't, but he uses this same spell twice more.  Once 
against Harry (Pg. 803) (Harry successfully uses a shield charm in 
defense).  Then against Sirius (also Pg. 803) (Harry puts Dolohov in 
a total body bind before he can finish is slashing movement.)  In 
between all this, Dolohov also shouts "Tarantallegra" toward Neville 
and "Accio Proph..."  

He has his voice back.  So, why no incantation?  

Also...Do we know what this spell is?  All I've been able to find is 
that it kncked Hermione out cold and made her ribs tender.  And a 
decription of the wand movement several times.

By the way, please be gentle with me, I'm new.
