HOME LIFE AND CORRESPONDENCE. 219 



Trinity College, Dublin, September 9, 1850. 



Madam, 



I feel much obliged by your sending me the interesting 

 specimens from Filey to examine, and still more for the kind 

 permission you give me to. keep the best of them ; but I have 

 not availed myself of this liberal offer, at least, to the full 

 extent, a branch of your plant being quite ample for my 

 purpose, and this I have taken off without greatly injuring 

 your specimen, which is herein returned. As some slight return, 

 I enclose specimens of the rare Carjpomitra Cabreras, Stenogramme 

 interrupta, and Gigartina pistillata, which I hope may be new 

 to you. And now for the Filey plant. I find, on comparison 

 with the American C. rosea, that your specimen is so nearly 

 identical that it must be regarded as the same species, and that 

 the Orkney specimen (C. Orcadensis) differs only in having a 

 broader frond. As I am unwilling, however, to make two 

 species of plants so nearly related, I propose reducing C. Orcadensis 

 of the Manual to the previous rosea, of which it will now con- 

 stitute a variety. It will therefore stand in the October number 

 of the " Phycologia " as C. rosea, var. Orcadensis, and I must give 

 in the Appendix another plate from your Filey plant as C. rosea, 

 vera. The figure and description having been prepared alto- 

 gether from the Orkney plant, I have allowed them to stand, 

 but have mentioned the Filey plant in the remarks under the 

 description, and stated my intention of figuring it hereafter. I 

 hope it may be found again, with both sorts of fruit. The fruit 

 in yours is Tetraspores, which are somewhat differently arranged 

 (as you properly observe) from the same parts in C. clavellosa. 



A neighbour of yours, Mrs. Hayden of York, has sent me a 

 specimen of C. rosea, also from Filey, but smaller than yours, 

 and not in fruit. I have named your specimens, and remain, 



Madam, very truly yours, 



W. H. Harvey. 



" The correspondence which had opened so auspiciously for me 

 went on for some months upon Algae. Dr. Harvey professed 

 himself glad of a correspondent from ' a new part of the coast, 

 and one little explored ;' and I, on the other hand, was proud to 

 find myself in the position of even making an attempt at being 

 useful to the author of the ' Phycologia Britannica.' But this
