Breaking away from its point of attachment, any current in the 
waters of the loch would tend to roll the mass about, and by thus 
causing each part of its surface in turn to be acted upon with 
tolerable uniformity by the light, varying both in direction and 
intensity and by contact with the bottom, existing inequalities in 
the surface would come to be averaged, and the figure approximate 
to that of a sphere as in the specimen exhibited. 
Mr. Wilkie stated that, in a shallow bay in a disused clay-hole 
in the vicinity of the city, he had often observed loosely 
golomerated spheres of the size of a marble formed in this 
manner by an allied species which does not branch so freely in 
a radial direction as does Cladophora egagropila, Linn. 
Specimens of the genus Barbula, as constituted by Dr. Braith- 
waite, and Dicranum capnodes, Stirton, a new moss from Ben 
Vorlich, Loch Lomond, were exhibited by Mr. James Stirton,
