How to install an older version of package via NuGet?

I want to install an older version of a package (Newtonsoft.Json). But NuGet rolls back.

PM> Install-Package Newtonsoft.Json -Version 4.0.5
Successfully installed 'Newtonsoft.Json 4.0.5'.
Install failed. Rolling back...
Install-Package : Already referencing a newer version of 'Newtonsoft.Json'.

Any help will be greatly appreciated.
