refer them. This species is a widely extended one, being found from New- 

 foundland to the Rocky Mountains. 



IT' 



A specimen of a Beaweed in a nodule, evidently a Fucus. It is not strictly 

 comparable with any of our modern Bpecies, :in<l until more material is ob- 

 tained it serins besl not to assign any specific name to it, although digitatus 

 would appear to be appropriate. 



FONTINALIS. 



Fragments of mosses are common in the nodules from Green's creek. 

 These appear to be chiefly of the genus Fontinalis, or one nearly related 

 to it. 



Jn addition to the above there were also found in the Green's creek nodules 

 various seeds. These require some further examination. 



BROMUS CILIATUS, L. 



A fragment of a leaf which shows a venation closely corresponding to 

 Bromus ciliatus, to which I would for the present refer it. This is a very 

 common Bpecies in thickets and damp places throughout Canada. The 

 specimen was collected by Mr. J. G. Miller from Green's creek. 



GEN. AND SP. UND. 



Among the specimen- sent us by Dr. G. M. Dawson was a seed collected 

 by Mr. J. B. Tyrrell, in 1887, from the Rolling river, Manitoba, two miles 

 above Ibart hill. The form and size seem to indicate that it is the seed of 

 a Conifer. 



LlGNIT] -. 



\ sample of lignite or indurated peat, collected by Dr. G. M. Dawson 

 from the interglacial deposits of Belly river, was presented in the form of 

 balsam mounts and loose material, all of which had been treated with potash, 



nitric acid, sulphuric acid, or chromic acid. In all cases the material was 



found to be very finely divided, none of the fragments being of sufficient 



-!/•■ to make reference to particular orders or genera possible. It was, how- 



r, quite possible to recognize fragments of sclerenchyma tissue, fragments 



i.| wood cells, Bpores of ferns, and what appeared to he the eztine "I' pollen 



H-. These latter, together with the few spores, constituted the bulk of 

 the recognizable material. There were also to be observed fragments of 

 epidermis, apparently of three different kinds, and in one instance two 

 stomata were found, though imperfectly preserved. The impression gained 

 from a careful examination of a large amount of material is that the
