On the Phases of Development of the Trichodina pediculus (?) . 269 



interior of Germany quite a different race of tame oxen was found, 

 much less in size, with smaller horns, and often without any : 

 this will be treated of in the next article. 



This same small race was, without doubt, found among the 

 Germanic tribes also here in Scandinavia, where the inhabitants, 

 accustomed to small cattle, looked upon those introduced by the 

 Jotens as so enormously large. That this race might exist at 

 one and the same time, and in the same country, both wild and 

 tame, is not more extraordinary than that the reindeer in Lap- 

 land and the swine in the whole of south and central Europe should 

 yet exist in the same tracts both in a wild and tame state. 



That the wildUrox from the earliest times was an object of chase 

 to the inhabitants here, is proved beyond contradiction by the 

 before-mentioned skeleton preserved in the museum at Lund. 

 This race of wild oxen has never lived in Scandinavia further 

 north than Scania, and even here the fossil remains occur for the 

 most part in the districts of Skytts, Bara and Wemmenhog. 

 Once only have I obtained a skull from Allerum in the district 

 of Luggude. 



We perhaps may be astonished at the thought that so colossal 

 an animal as an ox of this race, whose natural food was grass, 

 could winter in a country such as this, where the snow covers 

 the fields often during five to six months of the year, and where 

 the grass during that period either failed or was inaccessible. 

 But our astonishment ceases when we see how the cattle support 

 life during the winter in the forest tracts ; with what avidity they 

 bite off and devour the tender branches with their buds, and the 

 catkins of birch, hazel, sallow and other species of willow. Those 

 places where the Urox wintered were certainly thickly grown 

 with the above-named trees, and from them it sustained life. It 

 is not more surprising than to see the Elk live and winter in 

 climates which are much more severe than that in which the 

 Urox existed.

In examining the contents of a bottle of water procured from a 

 pool in the swampy part of Hampstead Heath, in the past month 

 (July), and during the drought prevailing at that time, I en- 

 countered an animalcule which I determined to be, most pro- 

 bably, the Trichodina pediculus (Ehr.) . Perceiving that the ani- 

 mal was disposed to remain in the same locality under the mi-
