se there was a connection between the intra-tracheal growth and the thyroid gland externally. The thyroidwas so firmly attached to the cricoid cartilage and upper threetracheal rings that it could not be separated from them. Thespace between the cricoid and first tracheal ring, and a portionof the external lateral lobe of the thyroid, which was firmly ad-herent to the cartilage at this point, were examined microscopic-ally, and he was able to prove positively that the thyroid tissuehad penetrated (through the interstitial membranes) to the per-ichondrium and submucosa on the inner surface of the trachea,the cartilage itself remaining intact. This observation of Pal-taufs is the first instance on record of normal thyroid gland tissuepenetrating to the interior of the trachea, although Orth,86 in his Pathological Anatomy. makes the statement that strumas,but particularly malignant neoplasms, could penetrate into the airpassages. Paltaufs conclusions, that these tracheal tumors springing

CLEMENT F. THEISEN 689 from thyroid tissue do not owe their origin to an intrauterinedeposit of thyroid tissue, are of great interest. They shouldtherefore not be called accessory thyroid tumors. They originatein extra-uterine life by penetration of the gland tissue betweenthe cricoid and the thyroid cartilages, between the cricoid andfirst tracheal ring, between the upper tracheal rings, and throughthe interstitial tracheal membrane itself, from without. Whenthis occurs it should be considered as a direct extension of anenlarged thyroid gland—a parenchymatous struma. Proof ofthis assertion is that the thyroid gland has really grown fast tothe cricoid cartilage, interstitial membranes, and upper trachealrings. This abnormal adhesion can be explained neither bypressure, nor by an inflammatory process, but can only haveoccurred during the formation and development of the thyroidgland, and only in the way that the fcetal gland, in these cases,must be united with the perichondrium of th
