been obtained, had it been honestly searched for ; in pi'oof of which 

 I refer to the following gentlemen who were present at the lecture, 

 all of whom are well known in Newcastle-on-Tyne, and any of 

 whom will testify to the strict truth of this statement : — T. L. 

 Gregson, Esq., Sheriff of Newcastle-on-T\Tie, Chairman ; Messrs. 

 A. Carse and M'Kendrick, Secretaries of the Mechanics' Institute ; 

 Mr. Geo. Bell, Member of Committee ; Mr. Pace, Chief Collector of 

 Borough Bates ; Mr. II. Lowry, railway goods' station ; and Mr. 

 Benson, Central Exchange News' Room, — all of Newcastle-on-Tyne. 

 Should CUmaxodns and Janassa be eventually classed as one genus, 

 the order will then stand Janassa bituminosa, J. imhricata, J. ovata, 

 and J. vermifonnis — J. linr/uceformis being merely a synonym of 

 J. ovata. Ashamed that, for the first time, I have to refute the 

 imputation of untruthfulness, 



I am. 



Yours obediently, 

 Newcastle-on-Tvne, T. P. Barkas, F.G.S.

[It is evident that, as the descriptions of Messrs. Atthey and 

 Barkas appeared in print on the same day, there can be no question 

 of priority of publication between them. The question really at issue 

 is, whether Mr. Barkas's having " publicly named " the species, at a 

 meeting of such a body as the Newcastle Mechanics' Institute, on the 

 28th of September 1868, gives him a priority over Mr. Atthey, whose 

 subsequently published pai^er was read at a meeting of a recognized 

 scientific society on the 0th of October following. We do not under- 

 stand Messrs. Atthey and Hancock, in their last paper, to have cast 

 any doubt iipon Mr. Barkas's veracity ; their statement seems to us 

 simply to relate to the want of any recorded evidence, for the 

 guidance of future pahjeontologists, of the species having been satis- 

 factorily described by Mr. Barkas on the occasion to which he refers.] 



On Exobasidium, Woronin. By H. Karstex. 

 Fusidhmi vaccinii, discovered in 1861 by Fuckel, and described 

 and figured by him in the ' Botanische Zeitung' (p. 2.51, tab. 10. 

 fig. 7), was made the siibject of a thorough investigation by Woro- 

 nin, who published his results, accompanied by good, characteristic 

 figures, in the ' Bericht der Verhandl. dor naturf. Gesellschaft in 

 Freiburg ' for 1867, p. 697. As Woronin found that the gonidin, which 

 are at first unilocular, but afterwards (as indeed Fuckel figures 

 them) multilocular, stand in fours (rarely in fives) on the summit 

 of the clavate ends of myceliuin-thrcads, which, standing in masses 

 parallel to each other vertically, form a sort of hymenimn, he thought 

 justly that the fungus should be separated from the genus Fusi- 

 diam and regarded as the type of a peculiar genus, Exobasidium ; 

 but he referred it incorrectly to a position among tlie Basidiomyceta^, 

 on account of its gonidia being placed upon clavate sterigmata. It 

 seemed to me, at least from the other statements of tlie develop- 

 mental history, that this arrangement could not be justified upon 

 this ground alone ; for I had recognized the mother cell of the
