2d. In localized infection take the tissues which bear the 
local lesions. 
, 3d. In selecting tissues which bear the local lesions, take by 
I preference such morbid conditions as are recent yet well devel¬ 
oped, and avoid such as have manifestly a complicated infection. 
It is a common thing to find tubercle, anthrax and other lesions 
complicated by the presence of pus organisms and other mi¬ 
crobes, and in such cases the search for the primary germ of the 
disease is correspondingly complicated and difficult. 
4th. Take the material from a subject which is newly killed 
or has only died very recently. In certain diseases septic mi¬ 
crobes from the skin, bowels or some other mucous surface, or 
which are already present in the circulating fluids, are propaga¬ 
ted with great rapidity, so that in a very few hours specimens 
are almost useless for examination or cultures. This is especi¬ 
ally true of the warm season and southern latitudes. 
5th. When the infection is generalized aim at securing one 
or more parenchymatous organs which are likely to contain an 
abundance of the pathogenic microbes with few or none of the 
extraneous or saprophytic ones. As example of such organs 
may be named the liver, kidney, spleen, lymph glands, heart 
and lung. 
6th. In securing the morbid specimen first clip the hair from 
the surface of the body where the incision is to be made, then 
wash it clean with soapsuds, followed by a mercuric chloride 
solution, 1:500. Wash the hands and disinfect them in the 
same way. The knife and forceps to be used should be cleansed 
and placed in, and taken direct from the carbolic acid solution* 
If greater security is desired they may be dipped in absolute 
I alcohol and burned off. 
! In case of a superficial local infection the infected part may 
! be seized with the sterilized forceps, cut out with the sterilized 
j knife, and transferred to and wrapped secureiy in a white cloth 
I thoroughly wrung out of the mercuric chloride or carbolic acid 
f solution, care being taken that it is not allowed to come in con- 
' tact with any other object.
