THE THYROID AND PARATHYROID 

 GLANDS. 



History Removal of the thyroid and parathyroids Removal 

 of parathyroids alone Removal of thyroid alone Thyroid

 lodoform and thyroidism Action of iodides on gummata and 

 atheroma Exophthalmic goitre Practical deductions. 



MUCH of the clinical and experimental work 

 which has been done in connection with these 

 glands can no longer be described as new, but it 

 will be helpful to mention in passing some of the 

 well-known results obtained by the first observers. 



HISTORY. 



As long ago as 1859, Schiff described the fatal
