Notes on a Large Scrotal Hernia Operated upon under Apothesine

an operation. He was discharged the next day. On 6th December,. 1924, the patient again sought admission. He came in with a very severe attack of bronchial asthma. The hernia had very appreciably increased. A little difficulty was experienced in effecting its reduction. He again expressed unwillingness to be operated upon. A truss was applied and the patient discharged. On 2nd February, 1925, t...

The Nerve Elements in Silver-stained Preparations of Cordylophora.

SYNOPSIS. The nervous sjstem in the hydranth of Cordylophora was stained by a modified Peters' silver method. Nerve elements are found onl) in the ectoderm, where the) form a dense plexus, oriented mainly longitudinally. The majoriu of the nerve cells, whether lying deep in the ectoderm or near the surface, carry a short hair, presumably sensory. These findings are compared to earlier reports o...

Intercellular Connections in the Outgrowing Stolon of Cordylophora

Outgrowth of the stolon in the hydroid Cordylophora has been studied at the cellular level. Staining experiments and histological examination indicate that the generative region of the stolon is at its base where interstitial cells are prominent. Cells in the ectoderm at the stolon tip appear to be actively synthesizing new perisarc as the tip advances over the substrate, rather than involved i...
