consequence of the operation had, after moulting, begun to 

 produce feathers characteristic of the normal male. Those birds 

 have been kept to the present time, and now show a complete 

 change to the cock-feathered type, except that the comb is reduced 

 in size as in the ordinary capon. The spurs, however, appear to 

 have their full growth. Since the Fj birds were certainly heter- 

 ozygous, and the few F 2 birds operated upon might have been 

 heterozygous for cock feathering, it became desirable to carry out 

 the operation on the pure Seabright cockerels which are always hen- 

 feathered. The change in them, as the birds before you show, 

 is as marked and as complete as in the Fi and F 2 birds. 



One bird after completely changing to cock-feathering (with 

 reduced comb also) began after six months to change back; 

 and, as is demonstrated by the bird, is at present in an inter- 

 mediate stage. The comb has begun to enlarge again. Pre- 

 sumably a small piece of the testis was left — not large enough at 

 first to prevent the change to cock-feathering — which has re- 

 generated so far, that, at the last moult, the new feathers were 

 affected.

The effect of painting the pancreas with adrenalin on glycemia 



and glycosuria. 



By I. S. Kleiner and S. J. Meltzer.

 feller Institute for Medical Research.] 



About fifteen years ago Herter and his coworkers reported 

 that painting the pancreas with adrenalin causes a considerable 

 glycosuria and they even assumed that the pronounced nature 

 of glycosuria following intraperitoneal injections appears to be 

 mainly attributable to the readiness with which the injected 

 adrenalin comes in contact with the pancreas. Vosburgh and 

 Richards reported later that the painting of the pancreas with 

 adrenalin produces considerable hyperglycemia. To our knowl- 

 edge the validity of these unusual statements was not confirmed 

 or even tested since their publication. We have carried out 

 recently a long series of experiments in which the hyperglycemia
