below in fig. 3. Fig. 6. The two upper meshes of fig. 5, magnified 

 six times, showing the ends of the vessels passing outwards, and 

 the longitudinal section of the scalariform vessels of the cylinder. 

 !Fig. 7. Longitudinal section of a portion of the cyhnder, magnified 

 six times, parallel to the meshes, showing no indication of medul- 

 lary rays. 

 Fig. 8. A vascular bundle and its accompanying cellular tissue from a section 

 of the original specimen of Lejpidodendron Harcourtii, Lindl. & 

 Hutt. The large cells surrounding the drawing are the parenchyma 

 of the circumference of the stem. The cellular tissue belonging to 

 the vascular bundle is composed of small cells with very delicate 

 walls. This tissue so readily decayed that I have never seen it in 

 any specimen of Stigmaria, or in any of these stems except this 

 Lepidodendron . 



DiscTTssioisr. 



Prof. MoEEis insisted on the necessity of the student of fossil 

 botany being* thoroughly acquainted with modern botany also. It 

 was from specimens discovered many years ago by Mr. Prestwich 

 that the true nature of the Stigmarice had been discovered ; and he 

 quite agreed with the author in regarding them as cryptogams, 

 and in no way connected with gymnosperms. The abundance of 

 cryptogamic spores in coal was hardly at present appreciated. 

 There were some varieties of coal almost exclusively composed of 

 such spores.

(Communicated by the Secretary of State for Foreign Afiairs.) 



[Abstract.] 



The writer stated that the works at Kaianoma have made con- 

 siderable progress since they were reported upon by Mr. Mitford 

 last year *. There are four seams of coal, each about 7 feet thick 

 and at a distance from each other of from 50 to 100 feet. Mr. Adams
