You ask where you can obtain copies of No. 20 and 21 of "Special Testimonies", Series B. We list these as No. 20, "Appeals for Unity," published in 1912 and No. 21, "Recreation," published about 1913. These two pamphlets do not carry the title "Series B," and a number on them. These are out-of-print and are becoming very, very scarce. (Arthur L. White)
