Includes the following articles:

• Band 21 – Ueber eine Methode zur Bestimmung (W14). Determining how the mass of electron changes with velocity.
• Band 23 – Uebe die Moeglichkeit einer neuen Pruefung (W17) & Beneerkungen zu der Notiz (W18) & Ueber die vom Relativitatsprinzip (W19). First is about Doppler effect and method for testing relativity theory; second relates to electron and its changing shape during motion; third is determination of E=mc2.
• Bands 26 through 28. Ueber die elektromagnetischen Grundgleichungen (W22 & its correction in v 27 = W26) & Ueber die in electronmagnetischen Felde (W23) & one other paper (W27). First is “fundamental equations of the electromagnetism of moving bodies” =  Relativity and Maxwell’s equations. Second (W23) is Relativity and ponderomotive effect, E here postulating perfect duality between electric and magnetic quantities.
