of Edinburgh, Session 1872-73. 
In any view of the case, however, it seems necessary, in connec- 
tion with my former notice, to make known the fact that green- 
heart as now imported , and generally used in marine works, is not, 
as was hitherto supposed to be the case, wholly proof against the 
ravages of the Limnoria terebrans , suggesting, perhaps, increased 
care in its selection, although I believe it must still be regarded as 
the most durable timber that can be employed in such works. It 
is almost unnecessary to add that these observations refer to locali- 
ties where the timber is exposed to what may be termed sea-water , 
and not to situations where, from admixture of fresh water or other 
causes, the ravages of the Limnoria are greatly mitigated or alto- 
gether unknown. 
The following Gentleman was elected a Fellow of the
