Where plaintiff relied on defendant agent's assurance that the purchaser of the plaintiff's leasehold interest would pay a bonus, so that the tenant would be safe in moving out, the liability of defendant to plaintiff is not the amount the purchaser of the lease would have paid had he performed, but is the loss occasioned plaintiff by defendant agent's wrongful or negligent act in giving the assurance.
