Informed by [Thomas] Woodward that Smith approves of his work ["Nereis Britannica"]. Inspired by his disupte with [Thomas] Velley [over floresence of plants and seaweed] to investigate seaweed fructification with a microscope, details some of his observations, particularly the production of seeds and air bladders, from examination of: '[Fucus] vesiculosus', 'F. spiralis', 'F.nodosus', 'F. carnaliculatus', 'F. siliquosus', 'F. digitatus, 'F. polyschides', 'F. palmatus', and 'Ulva umbilicalis'. Shall send samples of two or three sea plants. Sending his paper on 'Herniaria glabra' which rectifies other authors' previous errors, including sketch and specimen [see RelatedMaterial below]. Believes the lack of reviews for his book is due to his not having advertised it very widely.
