On the 20th of July, 1860, M. G. de Mortillet wrote a letter to Sig. Cornalia, president of the Italian Society of the Natural Sciences, at Milan,[37] in which, while mentioning the discoveries made in Switzerland, he suggested that similar antiquities might be found in the lakes of Lombardy. The reading of this letter led to a discussion which at once elicited one or two statements of archæological importance. The vice-president, Sig. Antonio Villa, recalled the fact that a bronze axe-head and some flint arrow-heads were found in the turf-bog of Bosisio, at a depth of 10 feet, which were described and figured in a Milan journal, _Il Fotografo_, 2nd August, 1856. The president also mentioned that he possessed weapons of a similar character, which were found, along with some human bones, in the peat-beds of Brenna. Shortly afterwards the celebrated naturalist Gastaldi, in an article in _Il Nuovo Cimento_, directed attention to certain antiquities which the turf-cutters were in the habit of finding in the "torbiera di Mercurago." (B. 37.) Subsequently Gastaldi visited this locality, and along with Professor Moro, of Arona (who first recognised the importance of the objects in question), made further researches in the peat at Mercurago, the result of which was to leave no doubt that they had here to deal with the remains of a true palafitte analogous to the pile-dwellings in the Swiss lakes. During the next two years Gastaldi's report was considerably enlarged by further finds at Mercurago. (B. 43 and 52.) About the same time that these discoveries at Mercurago were being made the existence of a palafitte in Lake Garda was surmised from the finding, at various times, of bronze implements and weapons in the harbour at Peschiera; but nothing further of a very definite character occurred till the summer of 1863, when Professors Desor and De Mortillet visited Lombardy in search of lake-dwellings. These eminent archæologists were joined by Professor Stoppani, and the immediate result of their investigations was the discovery of several settlements in the Lake of Varese and elsewhere. (B. 67.) Since then the lacustrine stations south of the Alps have greatly increased in number, there being now scarcely any of the smaller lakes and turbaries of North Italy that have not yielded more or fewer remains of this character.
