ber, I neverthelefs flatter myfelf with the hope that it may have its 

 ufe, by inducing the botanifts of diftant countries to beftow fome at- 

 tention upon this neglefted branch of a favourite fubjecl. For its 

 accuracy, as far as it extends, I can with fafety vouch, as I have ad- 

 mitted nothing that has not been the refult of my own aftual ob- 

 fervation, either upon Fuci found along the Norfolk fhore, or upon 

 a few which I have at various times received through the medium 

 of failors from the fouthern counties. 



It now only remains for me to add, diat a principal caufe of the 

 imperfection of the following Catalogue lies in our being wholly 

 unacquainted with the fr unification of many fpecies, as Fucus fac- 

 charinus, filum, * viridis, &c. together with almoft all the membra- 

 naceous Ulvce, and a great proportion of the Confervce ; which genus 

 I fhall hardly mention, as our knowledge of the fpecies is at prefent 

 fo imperfeft, that it requires more than ordinary fortune to find 

 two botanifts who agree in afligning to the flime plant the fame 

 name.

* Tbis Fucus, figured in the Ilora Danua, t.ib. 886, was, I beUcvc, firft difcovercd to 

 be a native of Great Britain by Sir Thomas Frankland, Bart. F. L. S, and is occafionally 

 gathered upon the Yarmouth beach. It deicrves to be remarked, tliat ^vhen frefn it is 

 of a beautiful orange colour, which it loles after hiving been a fhort time expcifcd to the 

 air, and becomes of a pale verdcgris green ; but if kept in frefh water, it changes this alfo 

 to a dark brown.
