APPENDIX. 



Since the preceding pages were set in type an article has 

 been received from Mr. Alfred Newton, an eminent English 

 oologist, detailing the elaborate methods employed by English 

 collectors of much experience in emptying and preparing eggs 

 for the cabinet. As these methods involve the use of more or 

 less complicated apparatus, which will not be generally procur- 

 able by the correspondents of the Institution, the new instruc- 

 tions are commended particularly to the use of those who are 

 forming cabinets for themselves, and are willing to give the time 

 and attention required. All correspondents who propose to 

 collect eggs for the Institution are, however, requested to read 

 carefully Mr. Newton's instructions, and to adopt his suggestions 

 as far as practicable.
