vertebrze and limb-bones ; tests of the soundness of the indications 
of resemblance to Nesodon and to Anoplotherium which the known 
and acquired parts ascribed to Macrauchenia had suggested. 
These requirements have been, at length, afforded by Burmeister’s 
description and figures of an almost entire skeleton, including verte- 
bre and limb-bones, with the skuil and dentition of a Macrauchenia 
patachonicha, which the late M. Bravard had obtained from the 
Pleistocene deposits of the Pampas of La Plata. 
The auchenian cervicals are associated with a tritrochanterian 
femur, a paleotherian astragalus and tridactyle foot. 
The lower molars, figured in pl. 135, fig. 7, of the ‘ Odontography,’ 
are correctly ascribed to Macrauchenia, and, with figs. 5 and 6, pl. 7, 
of Burmeister’s Memoir, show that the last molar differs from that 
of Paleotherium, and resembles that of Rhinoceros, in wanting the 
additional third lobe. But, perhaps, the most remarkable and unex- 
pected confirmation of Owen's early surmise of secondary alliance, is 
the occurrence in the Perissodactyle series of the exceptional state 
of dentition which is shown by the Anoplotherium in the Artiodac- 
tyle series, viz., a continuous dental series concomitant with equality 
of length of the crowns of the teeth, the canines not being developed, 
as such, but resembling in proportions those of the Anoplothere. 
H. Burmeister remarks, there is also a general resemblance-in the 
skull to that of the Anoplotherium (pp. 32, 33); but the orbit is quite 
circumscribed by bone, as in Hquus, while the nostrils are placed 
high up on the head, encroaching between the orbits, as in Toxodon. 
In reference to the alleged affinity of Macrauchenia to Nesodon, we 
now have the evidence of the grinding surface of the upper molars ; 
in which, although the crowns are shorter and transversely broader 
in Macrauchenia, they show, when worn down, three or four islands 
of enamel upon the inner half of the grinding surface.

HIS contains, besides some interesting Botanical, Antiquarian, 
and Agricultural papers,—(1.) The Rev. M. H. Close’s account 
of the general glaciation (by glacier-ice) of the rocks in the neigh- 
bourhood of Dublin (as shown by the map), the great glacial 
stream having invaded the area of the local ice-system of the Dublin 
and Wicklow Mountains, which, moreover, have modified its direc- 
tion, though at one time they seem to have been wholly subjected 
to the transverse passage of the great glacier, and have had gaps or 
passes, such as the Scalp, cut out across their ridges by its agency. 
(2.) Mr. J. B. Doyle’s note on the occurrence of a Knorria in 
the Lower Carboniferous Limestone Series of Kildare. (3.) Mr. 
H. B. S. Montgomery’s short but clear acoount of a new locality of 
granite blocks in the Carboniferous Limestone near Rathfarnham. 
(4.) Mr. A. Macalister’s notice of a remarkable specimen of Ulo- 
dendron, found at Hurlet, Renfrewshire, which has suggested to 
him, firstly, that most probably Ulodendron ranks nearer to the 
Cycadacee than to any other order; and that, ‘had we a Cycada-
