“ Another communication was made to the British Association, on the 
same subject, in September last; and at a recent meeting of the Geogra- 
phical Society of Berlin, Herr Ritter read a paper ‘On the Palework 
Buildings on the Shores of the Swiss Lakes ;’ in which he has endea- 
voured to point out two different forms, contra-distinguished, according 
to the old Scandinavian theory, into the Bronze and Stone periods : but, so 
far as I can yet learn, his knowledge of these structures has been gleaned 
altogether from the writings of my learned friend and correspondent, 
Dr. Ferdinand Keller, of Zurich, who, in addition to his work, ‘ Die 
Keltischen Pfahlbauten in den Schweitzerseen,’ published in 1854, and 
of which I have given an account in the Catalogue, has just issued another 
most interesting memoir in the ‘ Transactions of the Society for Father- 
land Antiquities in Zurich,’* in which he has done ample justice to our 
Trish investigations, copied several of our drawings, and acknowledged 
the originality of the Academy inthis matter. He has also recorded the 
discovery of similar structures in Savoy on the German side of the Lake 
of Constance. 
«What must strike one as the most remarkable fact attending these 
discoveries is, not only the extraordinary similarity of the structures 
themselves and the way in which they were placed, but that identity in 
form and use of the articles found therein, both warlike and those em- 
ployed in the chase, as well as the culinary and domestic implements, 
and the objects of personal decoration, or those employed in the toilet. 
The crannoges of Randalstown, Lough Rinn, and Castle Forbes, will 
make the forty-ninth of these fortified islands discovered and recorded in 
Ireland since my original description of Dunshaughlin in 1840. 
“The philologists trace the spread of the Celts by letters, words, and 
certain grammatical forms of expression in inscriptions, or by glosses and 
obsolete terms found in ancient writings, but have not as yet arrived at 
any very definite or precise conclusions, and certainly have established 
but few historical facts ; here, however, in these crannoges, although we 
cannot tell whether their makers and original occupiers spoke Sanscrit or 
Celtic, we have presented to us demonstrative proof of their habits of 
life, skill in the arts, and domestic usages preserved for hundreds of years, 
in what Keller not inaptly terms their ‘ water towns.’ These vestiges 
of man’s handiwork not only determine with greater precision the track 
and spread of this branch of the Indo-European family, but really afford 
us a tolerably good idea of their character and soctal condition. In the 
arrangement of our Museum I have, under the head of ‘ Finds,’ pre- 
served collections of typical articles procured from the Dunshaughlin and 
Strokestown crannoges; and when the Academy is in a condition to con-
