are not informed as to the wealth of cell division; 

 namely, we can cast a glance at the opposite side of cell 

 life and inform ourselves as to the number of cells that 

 are excluded from the reproductive act. Where we find 

 many acid nuclei interspersed amongst the ordinary 

 (with acid or basmic reacting nuclear juice), there the cell 

 new formation will remain in statu quo, and we will 

 have suffered a modification in its power of reproduction. 

 The potentia genera7idi of. the cells of a tissue is in inverse 

 proportion to the full development of acid nuclei. If, 

 after accepting this view, we return to the line of thought 

 outlined in the beginning, we cannot well do else than 

 differentiate between nuclei and nuclei, cells and cells, 

 according to whether they still possess or have lost the 

 most important and highest characteristic of the 

 phylogeny of cells, the power of reproduction. Of the 

 first one cannot doubt an anatomy of the highest grade ; 

 the latter sink down to mere simple building stones of 

 the tissue, and approach to the living intercellular sub- 

 stances. It appears to me, that according to this metliod of 

 experimentation (chromo-chemical) we can, step by step, 

 enter into the dark field of the life characteristics of the 

 elementary constituent parts. — St. L. Med. and /Surg.

The Malarial Parasite. — Investigation is in progress in In- 

 dia by Surgeon -Lieut.-Col. Lawrie and Surgeon-C;ipt. P. Hehir 

 of the Indian Medical Service and others. It began June 8, and 

 continued daily till Aug. 15. Fresh blood was taken and 

 stained preparations made from 116 cases. 



They allege that they have found the microscope to be mis- 

 leading and useless in the diagnosis of malaria and that there 

 is no parasite in that disease. " There is nothing in pure blood 

 but hsemocytes and leucocytes — red corpuscles and white cells." 

 They declare the so-called i3arasite of malaria to be nothing 

 more than a blue-stained nucleus of the leucocyte — th^:; white 

 cell. They say that the appearances described by Laveran and 

 others are to the found in health}^ blood.
