Remarks. 
(Note.— R od. refers to 
the radial and Tan. to 
the tangential fissure.) 
28 
Rad.— G rain straight, 
surface marked by 
longitudinal furrows 
corresponding with the 
annual rings. Tan . — 
Straight and smooth, 
sometimes curving 
slightly along the 
annual cylinders. 
* These two specimens 
had small knots in 
them, reducing their 
fissibility. [Fide 
Plate II, Nos. 55 and 
56.]
