2nd. That this series of changes may, under normal con- 
ditions, take place very slowly, so that, at the end of many 
months, and probably of even much longer periods, we are still 
enabled by the microscope to recognise and identify structures 
of great delicacy, such as elementary muscular fibre, and that 
this knowledge admits of important applications. 
3rd. That in this process of Histolysis, the first changes 
consist in the softening, disunion, and separation from each 
other of the morphic constituents of the tissues, each of which 
is then subjected to a process of disintegration. 
4th. That granules and granular corpuscles appear at an 
early period, arising probably from recombinations of the par- 
ticles of the organic fluids. Animalcules appear at this stage. 
5th. That granules, corpuscles, vesicles, cells, and granu- 
lar masses of various kinds and sizes, may form in fluids and 
tissues undergoing Histolysis, in which no such elements exist 
when in their normal states. 
6th. That generally in the progress of Histolysis, strue- 
tures very similar to those which are arranged under the first 
group, or the a-plastic elements of Histogenesis, form at diffe- 
rent stages, and that they exhibit the same modes of growth 
and development, but, like them, are incapable of producing 
higher forms. 
7th. That these morphic elements of Histolysis pass gra- 
dually into lower forms, exhibiting occasional instances of 
endogenous fissiparition, granular disintegration, and other 
changes, and that the cellular and corpuscular elements, by 
forming media for endosmose and imbibition, may aid in the 
disintegration of contiguous structures. 
8th. That certain elements may pass directly. into a state 
of molecular disintegration. 
9th. That certain corpuscles of peculiar characters, and not 
identical with any known normal elements, are occasionally 
formed. 
10th. That a period arrives at which chemico-physical
