It is hoped that these Albums will be the means of 

 permanently recording facts that would otherwise fall into 

 oblivioji, and zvhich may hereafter be commtihicated to investi- 

 gators into the laws of growth and disease. 



Copies of the tables of growth and development, and ex- 

 tracts from t/ie other observations, will be gladly received by the 

 Collective Investigation Committee. They should be sent at inter- 

 vals of a year, or of five years, addressed to The Secretary 

 of the Collective Investigation Committee, 161A, Strand, W.C. 

 It is not necessary that these copies should bear the name of 

 the person to whom they refer, if they are forwarded through 

 the medical adviser of the family who guarantees their truth- 

 fulness, and if they bear a motto, to prevent duplicates beitig 

 hereafter dealt with as separate documents. The motto should 

 be inscribed once for all on the Album, and, for the convenioice 

 of indexing, should consist of one letter and four figures, taken 

 at random, thus — M. 1437, or B. 2856.
