 gratified to say that the officers of the Liga Nacional Filipina para 

 la Proteccion de la Primera Infancia have commended the Bureau 

 of Science as shown elsewhere. On account of the largely in- 

 creased demand for this extract by the Liga, little has been 

 furnished to outside agencies. Dr. N. M. Saleeby had been secur- 

 ing regularly increasing quantities of the hydrolyzed extract, 

 which he has used in his practice with gratifying result. 



Iloilo Sugar Laboratory. — The work of the branch of the divi- 

 sion of organic chemistry maintained at Iloilo deserves special 

 mention. Messrs. Thurlow and Armstrong have been able to 

 do a great deal of work tovv^ard an extensive and intensive survey 

 of the sugar industry in Panay and Negros. The response of 

 the planters to the advice and counsel of these members of the 

 Bureau staff has been gratifying.
