March 25, 1834, 

 William Yarrell, Esq., in the Chair. 



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

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

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

 unprovided at the time at which the bird was killed with any of the 

 ordinary preserving powder or soap, he had used for its preservation 

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

 skin, well rubbed with this mixture, was brought through the inter- 

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

 and arrived in England uninjured. 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 new species of Shells forming 

 part of the collection made by Mr. Cuming 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 were accompanied by characters by Mr. G. B. Sowerby, and 

 consisted of five species of the
