No. 14. The upper portion of the head and horn-beam of a small 
animal, and somewhat resembling No.11. It has been much acted on 
by water; was found in the Shannon, at Drumsna Bridge, between the 
counties of Leitrim and Roscommon, on the 19th June, 1846, and was 
presented by the Shannon Commissioners. 
No. 15. A shed horn, with the brow antler attached; ‘‘ found in dig- 
ging at Lisduff, county Cavan,” in 1848, and presented by Lord Farn- 
ham. 
No. 16. The beam and a portion of the palm ofa left horn. No 
register, number, or label. 
No. 17. A portion of the skull and the beam and palm of the left 
horn of a full-grown animal. Presented to the Academy by W. R. 
Wilde, Esq., on the 23rd May, 1859. 
No. 18. A large horn-blade. No register, but evidently not belong- 
ing to any of the foregoing. 
No. 19. A large piece of a horn palm, marked ‘‘No. 4, found inthe 
present main channel | of the river] four feet below the original bottom, 
and about midway between Ballyconnell Mill and Island, in the Balli- 
namore and Ballyconnell districts.” 
No. 20. A large piece of horn-palm, with one side removed, showing 
the beautiful cancelli of the bone. 
21. A large piece of horn-palm broken off at the expansion of the 
beam. 
No. 22. Fragments of a beam and palm. 
No. 28. A brow antler covered with marl, and filled internally with 
crystals of protophosphate of iron ; a substance discovered and described 
in these bones, by Dr. Aldridge, some years ago. 
No. 24. The fragment of a beam and palm. 
No. 25. Two fragments; pieces of a palm. 
No. 26. A large tine, apparently found in clay, and filled with 
erystals, like No. 23. 
Nos. 27, 28, 29, 30, 31, 32, 33, and 34, are fragments of horns; so 
far as can be judged from their present condition, not belonging to any of 
the foregoing specimens. 
No. 35. An inferior maxilla, perfect; also fragments of seven other 
lower jaws, four right and three left; numbered from 36 to 42. The 
‘bony structure of the teeth and the edges of the alveoli are completely 
filled with the blue crystals of iron already alluded to. 
Nos. 48 to 47 are vertebre, evidently of different animals. No. 47 
is a sacrum, with a portion of the coccyx. No. 48, two scapule, found 
with Nos. 15 and17. No.49, four ribs. No. 50, two pelvic bones, much 
discoloured, and the interstices filled with blue matter. No. 51lincludes 
19 bones, of which 6 appear to have belonged to the same animal, viz., 
2 femora, 2 tibie, and 2 tarsal bones, and all marked with the same 
deep blue colour as the pelvic bones, No. 51, to which they appear to 
belong.. These bones are all very light and friable, and the blue co- 
louring matter has permeated their interior to a considerable distance. 
It does not here exist in the shape of crystals, like that in the horn- 
palms of No. 23, and in some of the teeth. No. 52 is a:femur, marked
