 recorded. Every such fact of any importance may thus, by means of 

 those short references, be readily traced and consulted, if wished for, 

 either in the original sources, in abstracts therefrom, or in the periodical

 the German Jahreshericht der Pharmacie, &c., published at Gottingen 

 since 1844, successively by Martins, Wiggers, Husemann, and at the 

 present time by Dragendorff. The same may be said, since 1857, of 

 the Report on the Progress of Pharmacy, as contained annually in the 

 Proceedings of the American Pharmaceutical Association, and likewise, 

 since 1870, of the Yearbook of Pharmacy, for which the profession is 

 indebted to the British Pharmaceutical Conference.
