J*: .^ Lead 2-ethylhexoate (also called lead 2-ethylhexanoate, lead <* -ethyleaproate, or lead "octoate*') is the lead salt of 2-ethylhexoie acid# (Its structural formula 1st Pb (oQC-CH-CHg-CHg-CHg-CH^) $ this vas given 2f incorrectly on the data sheet sent you by the Ministry of Supply) * It is a typical metallic soap (i*e* the salt of a metal and a fatty acid) and is insoluble in water, but soluble in certain organic solvents* It is not, in the strict usage of the term, an organolead compound, since its structure does not involve any Pb- C linkages, such as are present in tetraethyl- lead and in triethyl- and diethyllead salts* Also it is hardly conceivable that it could produce true organolead compounds, by chemical reaction* either in vitro or in vivo* As a lead salt of an organic acid| it is analogous i n m a n y ways to lead salts of inorganic aids, such as lead chloride, which are ionic in nature5 thus in ether, in which lead 2-ethylhexoate is soluble, it will tend to ionise as follows*- v- :

MEMORANDUM TO MEMBERS OF THE MEDICAL FACULTY Somewhat by chance, a few days ago, I came upon the written statement of a senior member of this Faculty to the effect that the research work of The Kettering Laboratory is of negligible significance, and that the Laboratory makes no contribution to the function and prestige of the University and Medical College except through its activities in graduate education.
