branchs have no nervous lobe. Extract of tlie pituitary of the skate Baia hatis 

 has a large effect in increasing the secretion of milk in a cat, when injected. It 

 has no effect on kidney volume or urinaiy flow, The cod, Gaduf! worrJiua, con- 

 tains a substance which acts as a mammary hormone on the cat, in both lobes 

 of the pituitary. The posterior fnervous) lobe also contains substances which 

 excite urinary secretion and canie rise of bloodpressure, as is the case with 

 other vertebrates. Min es.

 tion of Milk. In: Quart. Journ. Exp. Physiol., Bd. VI, S, 311, 1913. 



Injection of pituitary extract (posterior lobe) into goats causes an irame- 

 diate increase in milk secretion. The daily yield of milk is only slightly increas- 

 ed as a result of injection. The effect is not muscular, nor does it depend on 

 increased blood pressure. 



The milk secreted immediately after injection is richer in fat but other wise 

 like normal milk. Subsequently the milk obtained is poorer in fat. The pituitary 

 extract appears to act on the gland cells, causing them to turn out substances 

 already formed. Min es.

Intravenous injection of pituitary extract does not affect the total milk secretion 

 per diem. Min es.

Injections of pituitary extract into the triceps humeri of a lactating woman 

 caused a tingling Sensation in the breasts and increased the amount of milk pre- 

 sent shortly afterwards. There was no increase in the total yield of milk per 

 diem. Injections of corpus luteum caused no Sensation in the breasts and no 

 alteration in the milk available after the injection. Min es.

Removal of thyroid in sheep and lambs over seven months old was without 

 ill effects. The same Operation in lambs two months old caused cretinism. Com- 

 plete removal of thyroids and parathyroids in adult sheep was without effect. 

 The same Operation in lambs less than two months old caused fatal tetany. 

 Removal of parathyroids from the cretinous sheep, aged one year, was without 

 effect. Min es.

Thyroidectomy in the rabbit causes hypertrophy of the pituitary body. In six 

 months the pituitary had increased to about 3 times its normal size. Min es.
