70 Miscellaneous. 



nature and affinities to be made out. Two specie?, P. princcps 

 and P. rob'tstius, were described. A fossil conifer, first found in 

 Gaspe by Sir W. E. Logan, was referred to the Taxinece, and 

 described under the name of Prototaxites Logani. A lepido- 

 dendron (L. Gaspianuin) and two species of Knorria, one not 

 distinguishable from K. imbricata, were added to the Devonian 

 flora of Canada ; as also a Noeggerathia, of which fragments only 

 were obtained. The paper also described the mode of occurrence 

 of the small Devonian coal seam, discovered by Sir W. E. Logan 

 in Gaspe, probably the oldest true coal seam known. The occur- 

 rence of impressions of rain-marks, sun-cracks, &c, in these beds, 

 was also noticed. 



Professor Hunt's paper contained an elaborate exposition of those 

 views of his on the mode of metamorphism of rocks by chemical 

 changes in the presence of water and a moderate amount of heat, 

 which are already in part known to our readers. 



We hope, at some future time, to reprint bo:h papers, or abstracts 

 of them, in the Naturalist. 



Canadian Institute op Toronto. — New Trilobite. — In the 

 Number of the Canadian Journal for January, Professor Chapman 

 describes a new Canadian trilobite, and the Hypostoma of his 

 species, described in a former article, the Asaphus Canadensis* 

 The new species is named after the Professor of Natural History 

 in the University of Toronto, A. ffincksii. It is distinguished from 

 the other Canadian species of Asaphus, as indicated in the follow- 

 ing tabular summary of characters : —

Entozoa. — The same number contains a long article on those 

 remarkable creatures, the internal parasites, that infest man and 

 other animals, by Lucius Oiile, M.B. It professes to be mainly a 

 summary of the results of Von Siebold and Kuchenmeister, but 

 is well deserving of the study of medical students and young 

 naturalists. The writer very properly scouts the idea of the gt ne-
