ORIGIN OF LYMPHATICS IN BUFO 183 



APPENDIX 



At the time when the foregoing observations had ah-eady been 

 made, a reprint of a prehminary report by S. Fedorowicz on the 

 development of the lymph vessels in the larvae of Anura fell into 

 the writer's hands. (Untersuchmigen iiber die Entwicklung der 

 Lymphgefasse bei Anurenlarven. Vorlaufige Alitteilung. Ex- 

 trait dii Bulletin de I'Academie des Sciences de Cracovie, June, 

 1913. S. Fedorowicz). Although his observations pertain to the 

 development of the posterior lymph hearts in Bufo, he expresses 

 a view essentially similar to that advanced in this treatise. The 

 fact that two investigators have arrived at the same conclusions 

 independently of each other gives additional weight to their 

 work. Since Fedorowicz has the priority, the writer gladly 

 submits this contribution in corroboration of his work.
