 "VVilUam Yarrell, Esq., in the Chair. 



A specimen was exhibited of an Albntross presented to the So- 

 ciety by Lieut. Breton, Corr. Memb. Z. S., whose principai object in 

 calling the attention of the Society to it was to mention that, being 

 unprovided at the time at which the biid was kiiled with any of the 

 ordinary preserving po\vder or soap, he had used for its preservation 

 a mixtuie of Cayenne and black peppers with snuff and salt. The 

 skin, well rubbed with this niixtuie, was brought thiough the inter- 

 tropical regions in an ordinary trunk, affording free access to insects, 

 and arrived in England iininjured. Lieut. Breton conceives that it 

 may be advantageous to collectors to be made aware that the pre- 

 servation of skins can be secured by articles so constantly at hand as 

 those which he employed in this instance. 



The exhibition was resumed of the nevv species of Shells forming 

 part of the collection made by Mr. Ciiming on the western coast of 

 South America, and among the islands of the South Pacific Ocean. 

 Those brought on the present evening under the notice of the So- 

 ciety vvere accompanied by characters by Mr. G. B. So\verby, and 

 consisted of five species of the 



Genus Gastroch^na.
