My dear Owen

Having worked out pretty carefully my new articulated Balanus (to be call Arthrobalanus) I have become so much interested in the structure of the sessile Cirripedes, that I am dissecting 5 or 6 of the other genera. I work out mouths & cirri carefully, muscular structure & tunics of the sack, & a some of the structure of the viscera; whether this is worth doing I am not sure, but I have not forgotten your great kindness in acceding to my request of reading over this time my descriptions.— I have, however, strayed from my object, which was to ask, whether you could by any chance supply me with a few specimens in Spirits of any of the Sessile genera, for my specimens are all small & some immature. If the College had any large set of specimens, of any of the genera, perhaps it would be possible to let me have a few; I could return the parts, after having them drawn, preserved & dissected in Spirits

P.S. | Most, perhaps all of the shells, about which I more than once tormented you, I have found at Sowerby’s.—² proh pudor on me.
