This I have explicitly demonstrated in another place (Paris unter der dritten Republik), and will confine myself here to going very briefly over the argument.
I have the Zweiter Abdruck der dritten (2d reprint of 3d) in 4 vols.
Some of the most striking expressions of the race concept are found in Die Erziehung imdritten Reich (Education in the Third Reich), by Friedrich Alfred Beck, which was published in 1936.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "dritten" in a variety of sentences. We hope that you will now be able to make sentences using this word.
