Spurgeon Contradiction?

It seems to me that Spurgeon contradicted himself on the parable of the Sower and Seed. What do you think?

"I shall briefly treat of the third class, and may the Spirit of God assist me to deal faithfully with you. "And some fell among THORNS; and the thorns sprang up with it, and choked it." Now, this was good soil."

"I now close with the last character, namely, the GOOD GROUND. Of the good soil, as you will mark, we have but one in four." ("Parable of the Sower")
