20G Letters, Announcements, ^c. 



gentlemen interested in the progress of this work "will be able 

 to snpply rae with specimens of the birds mentioned in the 

 following list : — 



Atrichia. Syrrhaptes. 



Meliphaginae, especially Pterocles. 



Moho. Chionis, 



Climacteiis. Glareola. 



Trochilidfe. Opisthocomus. 



Chasmorhyiiclius. Eurypyga. 



Bucco. Heliornis. 



Trogou. Psophia. 



Batracliostomus, Caiiama. 



Centropus. Dicholoplius. 



Geococcyx. Tinamus. ■» 



Otidiphaps. Turnix. 

 Diduiiculus. 



It is important that the speeimens should be well preserved, 

 which is only possible if they are submerged, in a fresh con- 

 dition, in good spirit (no matter if the spirit be distilled 

 from figs, alfarroba, potatoes, or grapes), the stronger of 

 course the better. 



It is advisable to open the bird's belly by a small slit with- 

 out injuring the intestines, and to pour some spirit into its 

 throat and gullet. After the birds have remained for a time 

 in one vessel, it will be of great advantage to change the 

 spirit and then firmly to close the jar or bottle by securing 

 the stopper with grease, or bees' -wax (not sealing-wax or any 

 other resin), and by tying a piece of bladder over it. 



The preparations made of the specimens sent to the above 

 address will be added to the Collection of the University. 



Most important for the purpose stated above are nestlings ; 

 I should therefore feel greatly obliged for well-preserved 

 nestlings of almost any birds, with the exception of the more 

 common European sorts. Especially welcome would be the 

 very young or embryos of Casuariusy Dromaus, Apteryx 

 and Rhea, Penguins, Phcenicopterus, Procellariincp, Buceros, 

 Stringops. Yours &c.,
