In the first column, the letters 'St', 'V,' etc., refer to different series of rats 

 used. The number preceding the decimal point is the litter numl^er; the numfjcr 

 following is the individual number, 'm' refers to male, 'V to female. Under 

 'Dimensions of parathyroids,' the measurements for the two glands are listed 

 separately in columns 'a' and '!)' . 



The cephalo-caudal length (which is always the first of the 

 three dimensions given in the table) was calculated from the 

 number of sections, of known thickness, through which the 

 gland extended. The other dimensions represent the largest and 

 smallest diameters measured in the largest cross-section of the 

 gland, in the mounted sections. It should be noted, therefore, 

 that these dimensions are smaller than in the fresh gland, as 

 each linear dimension has probably undergone a shrinkage of at 

 least 10 per cent in the process of fixation, dehydration and em- 

 bedding. 



Generally speaking, the parathyroid presents a slightly flat- 

 tened, ellipsoidal form, the relative dimensions usually corre- 

 sponding in a general way to those of the associated lobe of the 

 thyroid. That is, in cross-section the outline usually appears 

 somewhat compressed medio-laterally; but the cephalo-caudal
