DATES OF PUBLICATION OF THE PARTS OF VOLUME VI. 
The dates of issue, as printed on the insides of the covers of the various parts, are approximations 
made in advance, and in each case antedate by a few days the time of actual issue to the sub- 
scribers. These dates should, therefore, be corrected as follows: 
Pp. 1-110, Pll. I-XI, published October 19, 1909. 
Pp. 1 1 1-300, Pll. XII-XXX, published December 16, 1912. 
Pp. 301-352, Pll. XXXI-XXXVII, published December 15, 1928.
