CHEMISTRY OF PEPSIN.

Gould spoke of the excellence of the kangaroo venison, and 
the introduction of the animal will be something more than 
a mere zoological luxury. There would be no difficulty, 
apparently, in acclimatising the alpaca in Australia, though 
where they had been introduced in this country the rot had 
seized them in consequence of the tenderness of their feet. 
It was part of his plan to point out what new and interesting 
birds would breed and were capable of acclimatisation in this 
country. As regards the pheasants, he might mention that 
the cheer presented to her Majesty lived for several years in 
the Royal Gardens at Buckingham Palace, and the monal 
was perfectly capable of bearing the severest winter. The list of 
birds that might also be introduced included the curasows, the 
oscellated turkey, the Cuban colin, the welcome colin, the 
Californian colin, the crested guinea-fowl, the brush turkey 
or tallegalla, the gelinotte or hazel hen of the Germans, the 
red-backed parakeet and crested grass parakeet, the Wonga 
pigeon, the crowned pigeon, the pied goose, the white-faced 
shieldrake, the red-billed duck, the dusky duck, the sommer 
duck, the ashv-headed goose, the Sandwich Island goose, the 
cereopsis goose, the bean goose, the Rock of Magellanic goose, 
the snow goose, the black swan, the black-necked swan, the 
Stanley crane, the white stork, the Mantchourian crane, the 
Australian crane, the laughing kingfisher. He remarked that 
the beaver and buzzard were formerly to be found in this 
country, and might be restored. He next drew attention to 
fish culture, and to specimen of insects and plants that might 
be acclimatised. In conclusion he announced the formation 
of a society for the acclimatisation of animals, to which Miss 
Burdett Coutts has subscribed £500, and has promised an 
annual subscription of £10. 
The heads of many of the animals referred to by Mr. 
Buckland were suspended on the walls of the apartments, 
and stuffed specimens of the birds were ranged on the 
tables. 
THE CHEMISTRY OE PEPSIN. 
By Harry Napier Draper, F.C.S.L. 
A discussion bearing upon the merits and demerits of 
pepsin has suggested the idea that a brief resume of the 
present state of our knowledge of its chemistry may not be 
unacceptable to the readers of this journal. By treating of
