1900E. F. Bashford tr. P. Ehrlich in Proc. R. Soc. LXVI. 448 The sifting of the material obtained by observation is rendered more difficult by the occurrence under normal conditions of a great number of quite unlooked for bodies furnished with haptophore groups and arising from diverse organs, and which we may designate collectively as haptines. 1902Brit. Med. Jrnl. 12 Apr. 918/1 Every normally functionating cell throws off large numbers of side chains, either as isolated complexes, or in connection with complement.
