Introduction 



This chapter gives the histology of the organs rather than the tissues, 

 presupposing a general knowledge of the latter subject. The nervous sys- 

 tem and the special sense organs are omitted, and for these subjects the 

 reader is referred to the excellent work of C. W. Ariens Kappers, G. Carl 

 Huber and E. C. Crosby (58), "The Comparative Anatomy of the Nervous 

 System of Vertebrates Including Man." 



The sections which serve as illustrations for this and for Chapter 4 were 

 fixed in a mixture of alcohol, formalin and acetic acid (70% alcohol 100 cc, 

 formalin 16 cc, acetic acid 5 cc.) for 4-24 hours, changed into 80% alcohol, 

 dehydrated in the usual way and imbedded in paraffin. This technique 

 gives satisfactory results with mouse tissue and is used in our laboratory
