ACKNOWLEDGMENTS. 
Dr GRANT is a most enthusiastic botanist. The 
professional duties of a doctor in Orkney, we all 
know, are very arduous, and it says much for him 
that amid them all he found pleasure in occupying 
his spare moments in making himself thoroughly 
acquainted with the flora of the Mainland and the 
South Isles, traversed by him in his _ professional 
rounds. He has undertaken, too, the laborious task 
of compiling the moss section of the cryptogamic 
flora of the same district, and has made a noteworthy 
collection of over 250 mosses. This is all the more 
creditable when we reflect that this was a neglected 
field, and had only previously been dealt with in a 
very superficial way. His work is a valuable con- 
tribution to this “Flora,” and renders it much more 
complete than otherwise it would have been. If 
any part of botanical work requires patience and 
expert knowledge it is this. My indebtedness to 
him in other respects is great. There are at least 
three plants which, but for him, would not have 
been included in the present list. These are :— 
Potamogeton pusillus, var. Berchtoldi ; Ranunculus 
scelerutus, and Cornus suecica. For specimens of 
these and much valuable help otherwise, I beg to 
express my indebtedness. 
To Professor JAMES W. H. Trait, M.A., M.D., 
E.R.S., F.L.8., my best thanks are due. His kindness 
in offering assistance and his readiness to help are 
pleasant remembrances. More especially is this the 
case when one knows how exacting are the duties
