ERRATA. 



On page 33, twentieth line, (in a small portion of the edition) the 

 word " California" has, by a slip of the types, been divided, and 

 the three first letters placed at the commencement of the sentence. 

 Page 64, twentieth line, " fig. 21," should read " fig. 11." 

 Page 77, fifteenth line, " plate II," should read " plate III." 

 Page 301, last line, should read " bees can subsist," etc.
