length. Towards the upper part of the trachea, on the right 

 side, was a dark red, glandular looking body, of a regular 

 form, three and one-half inches long by two inches wide ; 

 probably one lobe of the thyroid gland . 



The Lungs consisted of a single lobe on each side, without 

 any trace of division, but sending a prolongation upwards 

 from the apex. The left, in the male, measured twentyseven 

 inches along its outer surface ; greatest width ten inches, and 

 thickness two and one-fourth inches. Cells and lobules about 

 as large as in man. These organs, in both subjects, contained 

 very numerous diseased masses, from one-half an inch to two 

 inches in diameter, apparently a chronic affection, and consist- 

 ing of a deposit of very soft lymph with a mixture of pus, 

 the surrounding structure being quite healthy. The bronchial 

 and some of the cervical glands were similarly affected. The 

 inner surface of the trachea, also, was diseased at its upper 

 extremity, and on the anterior face, to the extent of two 

 inches by one and one-half inch, being thickened, rough and 

 opaque, but not properly ulcerated.
