§ 59. Remedies herein provided are additional. The remedy herein
provided for the recovery of the amount due the purchaser by action and
foreclosure shall be in addition to all other remedies allowed by law
with regard to certificates of sale and tax deeds, and shall not be
dependent upon them, or any of them; provided, however, that nothing in
this act contained shall be held to revive or validate any claim or
demand, the enforcement of which otherwise is barred by lapse of time.
