ne mol al the in ernatlOEal Congress meiygiene and Demcgraphy this af- ne yaoon. The ravages that this pest fds made in Porte Rico and the ef- kect ve campaign the United States mas made agains. it, was described by Dr. Bailey K. Ashford, Manager Of the Medical Cc.ps of the In ted States Army at San Juan. Perto Rleo, in an interesting address.
 pr. Ashford sa q the Porto Ricans had been exposed to the ravages ci the hookworm for centuries but since the Unised States Government had taken hold of the Island tn s range pest had been practically eralicated. The physical condition of the Porto Ricans, ga the doctor is now fifty per cent better than when the Goveln- menp began its campa gn against the hookworm about seven years ago.
 Since 1904 over 3,0GO victims of the hookworm have been treated in Porto Ric-' and with complete success. There rema ms about 100000 more to be treated, but these cases are not az gregated.
 Dr. Ashford tosk up the material benefit that has accrued to the ls- 9anl of Porto Rec because of this highly successful campaign gainst the Eookworm. He estlmat l that the commerce of the Island had in creased a least four hundred per cen because of the energy and activity of the native labcrers after they had been relieved of the hookworm dis ease.
 Talking on the subject of IS gnif- canoe of Physiological Age in Educa- tion,' Dr. C. Ward Crampton, Director of Physica! Training in the New York publ c schools, delivered an impress sive address to the Congress Dr. Cromot1'a he'd that physiological de- velopment rather than actual age should be the standard of class flea ton in the case of school children.
 '.From birth to maturity he sa d, children develop at different rates, some outslripping others in the race so that we find at the age af fourteen about one-.hiYG whe are already quite men and women One-thlrd III a trans tion period, and one-third quite immature. The differeIce between the mature and the immature are so marked that it IS astonlshing,' de- cared Dr. Cromption, that the idea of separating them for educat onai purposes has never cccuTed to our are from 90 to 50 per cent heavier; thrty to fly per cent stronger, ana ten 70 if cen per cent taller than the immature group of the same age. Ihe mental abi' ies show evSn mere striking liffel ence-the type CT mem- cry changes from rote to assoc at'Vs. the mental grasp is increased by an influx of newly ripened instincts, e. suling from the change from an un- sexual to sexual existence. The who.e attitude toward ] fe becomes attached 10 manly or Womanly things, aid the business of childhood is put behind. All these changes occur aOout the tme the voice leepens, the sec end molar teeth arrive. and &}iei eas Nv recognizable signs of maturity appear. In short, of these WHO aTs from twelve to fifteen in age some orc vcune men and other are children, regardless cf their ages in years oi progress n scaool.
 We find the same young men wi'" thoir ripened potential abilities sh- ting on the same benches, taught inc came. lessors and subject to the same T scinline as children, and the results are quite as poor as thes ce',o naturally be under these circums.ah res The fundamen al fact that 'nN ,,at,ra and immature are wholly all ferent ard should receive diheieh' educational or soc al treatment IS dis ,aoarded In the elementary schooi inc mature do badly. the ms" school frankly fitted to tAelr heeos' hey do from twenty tc fifty per cen natter than the immature. "Ai'' ;s at th.s psipt the educational sys- tenn tn nflexible basis of seholas',e- ;.m aud chronological age pfeahs down it suffers from lack ot ra'lop al classihcaton where mature slu 4a ;,nn,at,,ra children are brought 'o- gather in the same class room
