232 Dr. GooDENOUGH and Mr. WoodwardV Objerval'wns on 



This gentleman, fortnnately fituated near the Cornifli coaft, per- 

 haps the moft prohfic in Alga: of any part of the Britifli fhore, is 

 purfuing, with unremitting ardour, the inveftigation of the phy- 

 fiology of the marine plants; and, from the difcoveries he has 

 already made, expedtations may be formed that fome very valuable 

 ones refpeding this defideratum, may be obtained from his re- 

 fearches. 



While, therefore, we are prefenting our lift of fpecies, fo far from 

 deeming it or wilTiing it to be thought complete, we beg leave to 

 profefs how confcious we are of imperfedlion, and how fearful we 

 are of many important omiffions. We have only to confole our- 

 felves that we have fpared no pains in inveftigating, and faithfully 

 defcribing every thing within our reach. Hence we flatter ourfelves 

 that we have added fomewhat to the general ftock of knowledge 

 upon this fubje6l. We muft add, that we have received from 

 Mr. Stackhoufe fpecimens of three or four undoubtedly new fpe- 

 cies of Fuciis ; but as he is engaged in an excellent work on this 

 fubjeiff, part of which he has already publilhed under the name of 

 Nereis Briiamica, we did not think ourfelves authorifed to antici- 

 pate his publication by defcribing thofe fpecies. We fhall endea- 

 vour hereafter to incorporate them into our fyftem. 



One great fource of difficulty, in executing this treatife, took its 

 rife from the very great miftakcs which apperr in authors of the 

 firft refpeclabillty. Thus Mr. Hudfon had arranged our Fucus tenu- 

 ijfunus amongft his fpecies of U/va, and had called itUlva capillaris. 

 He had made F^ inflatus^ a plant of the divifion Alati^ to be a variety 

 of his Ceranoides, the Crifpus of Linnseus, one of the divifion 

 pronde pland avenii. Thefe and numberlefs errors of the like 

 kind we detected, partly by waiting for fpecimens in proper fruc- 

 tification, partly by confulting the Linnsean Herbarium, now, 



fortunately
