H. V. Wilson — Natural History Notes from Beaufort. 



The general character of the phenomena classed under the head of 

 reduction was discussed on the basis of observations made at Beaufort 

 during the past summer on hydroids and ascidians. 



When the hj^droid Eudendrium carneum is kept in laboratory- 

 aquaria reduction quickly affects the hydranths which become smooth, 

 mouthless sacs bearing a general morphological resemblance to the 

 planula larva and which fall off. Such bodies are not known to pos- 

 sess restitutive power. New hydranths are regenerated at the points 

 where the old fall off. 



The remarkable discoveries of Driesch on reduction and restitu- 

 tion in ascidians were described, and observations on these processes 

 in Peroyliora viridis were reported. These latter dealt especially with 

 the remodeling of pieces of stolon into little ascidians. A simple 

 method of getting clean fresh stolons for experimentation was inci- 

 dentally described. 



Frank C. Vilbrandt — Some Problems in Luhrication. 



The problems of lubricant manufacture and lubrication resolve 

 themselves into (1) the recognition of the refining "problems, (2) the 

 danger of overstressing motor gas production at the expense of the 

 lubricating fraction, (3) the lack of knowledge of the lubricating 

 principle in oils, (4) the absence of an ideal lubricant on the market 

 today, (5) the inability to properly evaluate lubricants by present 

 laboratory tests. 



The possibility of correlating the action of the heat exposure to 

 which oils are subjected in an internal combustion engine to that to 

 which it is subjected in the flash and fire point tests in control work 

 has suggested a new method for testing the stability of such an oil. 

 The method, consisting of diluting the quenched residue from the fire 

 test with pure gasoline and filtering the same through a clear filter
