APPENDICES. 
quarterly in Jan., April, July and October, appearing fairly regularly 
about the 1st of the month. Rarely very late, when apology is made; 
as instance, the number for Oct. 1905 did not come out until the end of 
November. Commonly quoted only with the year, the volumes are 
regularly numbered in series, six volumes to a series.

Collaborated with Selby in the production of Illustrations of Orni- 
thology, the details of pubhcation of which were given by Sherbom in 
the Ibis, April 1894 and corrected in the Ibis, 1899, p. 483. As only the 
years were given for the second series, further details are required, and 
I here add the following : In the Mag. Zool. Botany (edited by Jardine) 
for June 1837 it is noted that the 1st number is pubhshed ; parts wiU 
appear at intervals of six weeks to two months, and will each contain 
6 illustrations. This first number is reviewed in the Charlesworth Magazine 
for June 1837. In the October number of Jardine’s Magazine an advertise- 
ment states that the first and second parts have been pubhshed and that 
the third part is nearly ready.
