irank which it had attained, by his great talents, indefatigable industry, 

 sound judgement, and enlarged views as a naturalist ; by the high esti- 

 mation in which he had long been held by men of science all over the 

 world; by the excellence of those valuable and accurate works in which 

 he had done so much to promote and improve the study of natural history; 

 and especially by the qualities of his heart, mind, and temper, for which 

 his memory would long be revered by those who had enjoyed the happi- 

 ness of his friendship. He could not forbear expressing what he felt on 

 the present occasion ; and his anxiety that whatever choice might be 

 made by the Society to fill the vacancy in its Chair, should be such as 

 t^rould contribute to its prosperity, however impossible it might be ade- 

 quately to supply the loss which it had now so much to regret. 



j^pril 15. — A Letter was read, addressed to the Secretary, from 

 Charles Lucian Bonaparte, Prince of Musignano, F.M.L.S., dated on 

 board the Delaware, near Gibraltar, March 20, 1828, containing the fol- 

 lowing notice relative to the migration of certain birds. " A few day- 

 " ago, being 500 miles from the coasts of Portugal, 400 from those of 

 " Africa, &c. we were agreably surprised by the appearance of a few 

 *' Swallows, Hirundo urbica and rustica. This, however extraordinary, 

 " might have been explained by an easterly gale, which had cut off the 

 " Swallows migrating from the Main to Madeira, only 200 miles distant 

 ** from us ; but what was my surprise on observing several small Warblere 

 *' hopping about the deck and rigging ! These poor little strangers, ex- 

 " hausted as they were, were soon caught and brought to me. The 

 " following short Hst is that of the species. 



" 1. Sylvia trochilus. 2. Sylvia erithacus fTethys,Temm.). 3. Syl*- 

 " via Suecica, or rather a similar species which I have already received 

 " from Egypt and Barbary. 4. A species new to Europe, and perhaps 

 " even a nondescript, having the plumage of an j^nthus, and which I 

 ** think belongs (as Sylvia cysticola and others) to the hitherto African 

 ** genus Malurus. This, however, must rest undecided, my specimen 

 *' missing its tail, which was pulled off by the sailor who caught it." 



A Paper was read On the Mammary Organs of the Kanguroo: by 

 John Morgan, Esq., F.R.S., &c., in which a detailed account was given 

 of a recent dissection of these parts, both in the virgin and in the im- 

 pregnated animal; together with the authour's opinions respecting the
