2^2 Dr. Goodenough and Mr, Woodward'; Obfervathns on 



This gentleman, fortunately fitnated near the Cornifh coaft, per- 

 haps the moli prolific in Alga: of any part of the Britith fhore, is 

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

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

 already made, expectations may be formed that fome very valuable 

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

 iearches. « 



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

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

 profeis how conicious we are of imperfection, and how fearful \se 

 are of many important omiflions. 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 iubjeel:. We muft add, that we have received from 

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

 cies of Fucus : but as he is enc;an;ed in an excellent work on this 

 fubjedt, part of which he has already published under the name of 

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

 pate his publication by defcribing thofe fpecies. We (hall endea- 

 vour hereafter to incorporate them into our fyftem. i 



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

 rife from the very great miftakes which appear in authors of the 

 firtt refpeciability. Thus Mr. Hudfon had arranged our Fucus ienu- 

 ijjimu; amongft his fpecies of Ulva> and had called it Ulva capillarh* 

 He had made F. infiatns, a plant of the divifion Alati, to be a variety 

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

 Fronde plana avenia. Thefe and numberlefs errors of the like 

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

 tification, partly by confulting the Linnasan Herbarium, now, 



fortunately
