Introduces himself to Smith on strength of his belief that all naturalists in the world should be in communication and promote their studies by exchanging materials and observations. He and Bivona both desire to establish a correspondence with Smith. Sends a fasciculus of his of 16 Sicilian plants [extant]. Publishing a work on new Sicilian genera and species, principally fish, zoophytes, and marine plants; will send copies to Smith and Linnean Society and sends plates of fish now [extant].

Requests to be proposed a FMLS or corresponding member. They intend to institute a Sicilian Linnean Society, modelled on the British one. Lists papers he would like published in England. Sending north American and Sicilian plants for comparison with Linnaean specimens, including 'Euphorbia myrsinites'.

"Fasciculus of 16 Sicilian plants", list of plants that will appear in the work [1 p].

Plates of 21 fish, uncoloured [7 pp].

Encloses specimens: possible new 'Saxifraga', observations; 'Euphorbia hibernica' in flowering spring state, Smith's "English botany" figure does not entirely accord with the Irish plant; a 'Juncus' from County Whiclow that grows to 7 or 8 feet high.

Asks if the Irish 'Arbutus unedo' is to ever appear in "English botany"; wishes he was a curator, as gentlemen's gardeners call themselves, so that he might have better interest with [James] Sowerby. Does not think the 'Hypericum calycinum' of "English botany" is indigenous to Ireland, [James Townsend] Mackay [(1775-1862), curator of Botanic Garden, Trinity College, Dublin] concurs; fears many such mistakes occur. Asks if Smith's new edition of "Introduction to Botany" contains new additions.

Asks if his bundle of Irish mosses is still unexplored, noticing that many are in "English botany" without mention of himself. 'Gnaphalium margaritaceum' common to Ireland.

Circumstances of a "cruel war" cuts him off from Smith's "fortunate homeland, fair and free cradle of the liberal arts". Sends through the Stockholm Academy [of Sciences] his new edition of a work by "the divine Linnaeus" [probably fourth edition of "Philosophia botanica"], which he has dedicated to the Linnean Society. Nothing "more fervently desired by all good men and scholars than the resumption of trade with England"; keen to receive the latest additions to [John] Sibthorp's work edited by Smith ["Flora Graeca"].
