“…The differences between the skeletal maturities of the two hands was not related to the speed of skeletal development. 4. The mean difference between skeletal age and chronological age in each hand was greater than 6 months throughout the age range of 2 years to 17 years.…”

In assessing skeletal age it is customary to examine roentgenograms of only one hand and wrist on the assumption that pronounced differences between the two sides are comparatively rare. Although homologous parts of the two sides of the skeleton may show considerable differences in development, the bulk of available evidence supports the thesis that, for all practical purposes, discrepancies between the two sides are too insignificant to constitute a source of error in the determination of skeletal status.1-8 This inference is derived from investigations of the number and size of ossification centers in the hand and wrist, chronological order of appearance of the carpal bones and secondary epiphyses, and detailed measurements of the carpal area.

“…Without seeking to present an adequate survey or bibliography of the work which is largely based upon Pryor's pioneer investigations one might refer to Miss Sawtell's recent work in which she extended the method to include lower end of radius and ulna (6,7). That there is value in this method there is no doubt.…”

Observations on the growth and nitrogen retentions of a group of infants fed undiluted milk have been reported.1 This type of feeding resulted in an increased rate of growth in both weight and length, accompanied by nitrogen retention values greater than those of infants receiving less food. It is my purpose in this paper to record the observations concerning the calcium and phosphorus metabolism of these infants.The type of feeding and the technic of collection of excreta were reported in detail in the previous paper. The infants received undiluted lactic acid milk with the addition of corn syrup (6 per cent of the volume of the milk). The quantity was gradually increased from 600 cc. of milk at 1 month of age to 1,000 cc. (1 quart) at 6 months of age. One teaspoonful of cod liver oil and 1 or 2 ounces of orange juice were given daily. The calcium content of food, urine and feces 2 was determined by a volumetric modification of McCrudden's°m ethod. The Fiske-Subbarow 4 technic was employed for the determi¬ nation of phosphorus.A review of the literature fails to reveal many studies satisfactory for comparison. The calcium and phosphorus retentions reported by
