The Formulation of the Natural Sfiennt. 



The Theory of Panplasm. 



It appears desirable that the modern theory of heredity 

 should be designated by a brief and appropriate name, and 

 accordingly I propose the term " Panplasm," and that the the- 

 ory be called " The Theory of Panplasm." By panplasm will 

 be understood the physical basis of hereditary transmission, 

 which is supposed to be distributed through all cells, and 

 which accounts for the phenomena of sexual reproduction, re- 

 generation and asexual reproduction. Panplasm is not a col- 

 lection of gemmules or biophors. The term " panplasm " was 

 first used by me at a meeting of the Society of Arts, in Boston, 

 November 14, 1895. 



On another occasion I hope to discuss the theories of pan- 

 genesis and panplasm in their historical aspects. 



THE FORMULATION OF THE NATURAL SCIENCES. 1 



By E. D. Cope. 



Formulation is the method of presentation of the forms of 

 our thoughts. Our observations of the facts of material nature 

 are embodied in such classifications as we think best express 

 their relations, and by means of these classification^ expressed 

 in language, we convey to others our conclusions in the pre- 

 mises. As the vehicle of presentation, formulation is one of 

 the aspects of language, which as the medium of communica- 

 tion between men, enables them to accumulate knowledge. 

 It is highly important then that the system of formulation 

 should be uniform, so as to convey definite meaning and pre- 

 serve the truth. The vast number of facts to be marshaled in 

 orderly array, which constitute the natural sciences, require a
