Very likely.  The 19th century did _not_ invent the slashed grace note 
notation, only the convention that a slashed grace note represents an 
'acciaccatura' or 'short appoggiatura', while an unslashed one represents a 
'long appoggiatura'.  A slashed quaver  grace note in Haydn means exactly the 
same as an unslashed semiquaver one; the performer must decide from the context 
whether 'long' or 'short' is intended.
