78 MOSSES AND LIVERWORTS 



more of the teeth taken from the same moss, but 

 here they have purposely been drawn in profile, 

 and we then see, by their somewhat jagged out- 

 line, that some of the bars are evidently raised 

 above the other parts of the teeth, in relief, so to 

 speak ; this is shown very clearly in the tooth on 

 the extreme right. Fig. 12 of the same plate 

 represents a few of the small teeth from the 

 capsule of the Wavy-leaved Hair-moss (Catharinea 

 nndulata}, and here the markings follow the out- 

 line of the teeth themselves. These teeth make 

 extremely beautiful objects for the microscope, 

 being coloured a bright golden yellow, marked and 

 picked out in various shades of crimson. The 

 teeth drawn at fig. 13 (as also, on a larger scale, 

 at Plate V.a, fig. 13) are throughout of a deep 

 crimson colour. They are, moreover, delicately 

 marked and barred, and each tooth, it will be 

 noticed, is cleft down the centre into two distinct 

 portions, which, towards the base, are connected at 

 various points by transverse bars ; they are taken 

 from the long, oval capsule of the Broom Fork- 

 moss (Dicranum scoparium), already referred to, 

 a dweller on shady banks and in woods. Fig. 7 of 

 Plate V.a is a tooth of the beautiful capsule of the 

 Swan-neck Thyme Thread-moss (Mnium hornum), 

 and, again, is tinted a bright golden yellow. The 

 one drawn at fig. 9 is taken from the Sessile 

 Grimmia (Grimmia apocarpa), to which plant I 

 shall have occasion to refer again later on. The
