    ment, &c., issues in amoeboid forms from its cellulose investment, which seems to be, as in many other instances, secreted by, and common to, a congeries of amoeboid bodies, thus assuming the specific form of Mucor. But there is no “ transformation” here of the protoplasm, no perish- ing. The amoeboid cells come forth at once and do not bore holes through the cell-wall as the Mycetozoa family when developed in the vegetable cell. Hence, unless the protoplasm issues at once in an amoeboid form, or forms, as a whole, as from the cell of (Edogonium, &c., or in plu- rality, as from the filaments and pin-head-like capsule of unmatured sporidia in Mucor, &c., I should still be inclined to view the product as not of the same, but of a different organism. No doubt you saw the statement I last made of the probable repro- ductive process by impregnation in the Rhizopoda in the xvth vol. of the £ Annals,’ p. 172. I found in a pair of Difflugia urceolata (Carter) in zygosis, when crushed under the microscope, a number of monad-like monociliated, polymorphic bodies in active movement; the usual nucleated cells much larger; and apparently some of the latter which had become polymorphic or amoebiform. The origin of the nucleated cells I had not been able to ascertain— that is, from what part of the Difflugia they come. That of the monad- like bodies I knew to have come from the nucleus, which frequently (under reproductive circumstances ?) breaks up into these bodies, and therefore, in this case, was not present—had thus disappeared; while the amoeboid bodies without cilium seemed to be but a more advanced state of the passive nucleated or ovi-like cells. Thus I inferred that the small monociliated bodies coming from the nucleus were the male elements, and the larger nucleated cells the female elements, which, meeting together in the body of the parent, were, in their plastic state, thus brought together at the most favourable moment for impregnation, i. e. for the blending of the two elements. While the active amoeboid bodies without cilium might have been the product after impregnation, thus prepared for independent existence when the parent might choose to throw them off, or might become effete and thus by dissolution allow them to escape into the water. I have much more that I could state to you on the subject, but neither my leisure nor your patience, I fear, admits of the extension. Sufficient however has been written to show you the amount of interest I still take in these matters, and thus to prove to you how acceptable was the copy of your paper. I am, my dear Sir, Yours very truly, Henry Carter. London : Printed by William Clowes & Sons, Stamford Street and Charing Cross.
