the hollow cone of the fibro-calcareous sheath, and enlarging rapidly 

 as it extends outwards to, a considerable distance. This horny cup 

 formed the anterior chamber of the Belemnite, and contained the 

 ink-bag and some of the viscera.'* Owen subsequently traced a 

 similarly organized membrane continued backwards from the margin 

 of the alveolus, where Buckland's * capsule ' commences, " to line the 

 alveolar cavity of the spathose guard," and to cover the exterior sur- 

 face of the guard itself ; the first description of which latter struc- 

 ture we find in the following words of his memoir, * Phil. Trans.' 1844, 

 p. 69 : — "The exterior surface of the spathose guard of the Belem- 

 nites of the Oxford clay, though smoother than in some other spe- 

 cies, is minutely granular, and occasionally presents faint traces of 

 vascular impressions, proving it to have been invested by an organized 

 membrane of the living Cephalopods." With his usual cautious ex- 

 actitude he forbears to extend to this investing organized membrane 

 the term ' capsule,' which his predecessor had correctly restricted to 

 that part which, so far as it truly performs the function of a capsule, 

 commences, as Dr. Buckland describes, where the fibro-calcareous 

 sheath terminates. Every fact has its value ; but this varies inde- 

 finitely, and does not become greater, when, by an abuse of terms, a 

 small particular is laid claim to by a self-asserted discoverer.
