1. denies that Cornelis over de Linden did not understand the manuscript as he wrote to Verwijs,

3. denies the role of Ernest Stadermann,
4. denies that Verwijs called the OLB a hoax in a letter to Johan Winkler,
5. denies that Haverschmidt wrote to Leendert over the Linden, that he did not participate and even didn't know Cornelis over de Linden.

This is not about Haverschmidt or Verwijs or what Jensma thought or not, it is about what Cornelus' grandson recalled:
"In it a scene is sketched about Cornelis Over de Linden who finished some pieces of the text during daytime, and who during the evening, together with two learned doctors, re-read the writing and then, as recalled by Cornelis' grandson, the three men roared with laughter: "They'll never believe it '.
These 'two learned doctors' could be anyone.
