Letters, Announcements , fyc. 
gentlemen interested in the progress of this work will be able 
to supply me with specimens of the birds mentioned in the 
following list:— 
Atrichia. 
Syrrhaptes. 
Meliphaginse, especially 
Pterocles. 
Moho. 
Chionis. 
Climacteris. 
Glareola. 
Trochilidse. 
Opisthocomus. 
Chasmorhynchus. * 
Eurypyga. 
Bucco. 
Heliornis. 
Trogon. 
Psophia. 
Batrachostomus. 
Cariama. 
Centropus. 
Dicholophus. 
Geococcyx. 
Tinamus. 
Otidiphaps. 
Turnix. 
Didunculus. 
It is important that the specimens 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 Casuarius , Dromceus, Apteryx 
and Rhea, Penguins, Phcenicopterus, Procellariince, Buceros , 
String ops. Yours &c., 
H. Gadow.
