AB The tonsils are two masses of lymphoid tissue placed one in each tonsillar fossa and projecting into the oropharynx. They are oblong in shape with the long axis vertical. They are from 1.75 to 2.5 cm. in length and from 1.5 to 2 cm. in transverse diameter. In children under the age of eight they are usually larger, from 2.5 to 3 cm. in long axis by 1.5 to 2.5 in transverse diameter. They are covered by stratified epithelium of the mucous membrane and their pharyngeal surface is marked by small apertures which indicate the openings of the crypts. The epithelial lining of the crypts is reflected from the surface covering.The tonsils are composed almost entirely of lymphoid tissue which at intervals is aggregated into lymph nodes in which the lymph cells are more intimately arranged than elsewhere. The lymphoid
