The speaker then proceeded to show the way in which the 
‘ynthesis of zinc-ethyl could be effected ; it is, however, un- 
Recessary to follow the equations in detail, because, having al- 
teady explained the manner in which alcohol can be syn- 
thesised from acetylene, it is obvious that zinc-ethyl can be 
directly derived from that fluid. ; :
