hour there still remains a portion of the acid combined with jijlvcerol 

 in the foi'm of a m(tno-acid. 



Gljceroltrisulphuric acid was prepared by me according to Claksson 

 from anhydrous glycerol and chlorosulphuric acid. 1.619 grams of 

 the acid was dissolved in water and boiled foi- an hour, the solu- 

 tion was neutralised with barium hydroxide and the resulting bai-ium 

 sulphate weighed. If the sulphuric acid had been eliminated comple- 

 tely 3.411 grams of barium sulphate ought to have been formed but 

 only 2.121 grams were found; therefore 0.542 grams of sulphuric 

 acid was left in combination with glycei'ol. 



The above experiments, therefore, throw a little more light on 

 the sulphuric acid saponification of fats. Further communications 

 will follow shortly.

Palaeontology. — "0/z JJnIichkun vespi/ornw sp. nov. from the 

 hrk'k-earth of Tcf/ekn." By Mr. Clemend Reid F. R. S. and 

 Mrs Eleanor M. ReidB.Sc. (Communicated by Prof. G. A. F.

In our paper on the Fossil Flora of Tegelen published in 1907 ^) 

 we figured a fruit provisionally referred to Rlujndiospora. though it 

 did not possess the articulate beak of that genus. All the specimens 

 then available were so much distorted and injured by germination 

 that it was difficult to determine what the character of the perfect 

 fruit would be. In addition to this, the most perfect specimen appeared 

 to possess a quadrate base and 8 setae, characters unknown in 

 DuUchiuiii, to which genus the fruit w^as in other respects comparable. 



Since the publication of our paper we have obtained more material, 

 thanks to the kindness of Dr. Lorie and Baron L. Greindl. This 

 new material and a closer examination of the specimens before col- 

 lected, enables us now to describe the fruit as a new species belonging 

 to Dtdlehium, a genus now confined to America, though already 

 recorded by Dr. N. Hartz as occurring in an interglacial peat-moss 

 in Denmark"). Dr. Hartz's specimens are referred, we think correctly, 

 to the only living species, Didlchmui .spat/iaceuiii; our fruits are very 

 different.
