TL;DR: The structure and histogenesis of hair and nails are discussed in relation to mechanisms by which trace elements are incorporated into these tissues and some of the problems involved in analysis are presented.

TL;DR: Experimental infections in both sexes of the Chapel Hill, NC, strain of laboratory mice showed that tissue mutilation followed by abscessing may result from nymphal migration, and there was evidence that migration might elicit a larva migrans response and that an initial infection might sensitize the host to parasite antigens.

TL;DR: The distinction between biosphere and macroecology (of man) is a device of communication that makes it convenient to select from the former those factors that have a more direct effect upon man and, thus, deserve priority in our concern as discussed by the authors.

TL;DR: It is the thesis that some of the important causal factors that the authors haven’t recognized are, nevertheless, rather apparent if they but consider the map form, which is a special kind of graph, and offers enormous advantages in that it clearly demonstrates a three-variable relationship.
