NOTE. This chapter gives the membership of the “old” Commissions (listed by Commission number), as they were re-affiliated to the new Divisions that were established at the XXVIII GA in 2012. These Commissions ceased to exist at the XXIX GA and replaced by the new Commissions (se Chapter IX of these Transactions). The membership of the new Commissions was highly provisional and incomplete at the time of the XXIX GA (August 2015), therefore it is not reported here and it will be published in the next issue of the Transactions B.
