ACKNOWLEDGMENT
Many people have aided the author in carrying out the 
investigation for this dissertation to a satisfactory conclu
sion.  First of all,  sincere appreciation is expressed to the 
people  of this nation,  who  through their elected representa
tives,  passed Public Law 346,  the  "G.I.  Bill,f.  Without the 
financial assistance from the Veterans Administration,  an in
strument of the federal government set up to aid the  veteran, 
this work would never have been possible.
The School of Mineral Industries of the Pennsylvania 
State College through its Division of Fuel Technology has also 
helped the present  Investigator.  Appreciation is gratefully 
acknowledged to all the members of the Division from the Head 
of the Division, Dr.  C.  G. Wright,  down to the graduate as
sistants.  Special  thanks are due Dr.  C.  R.  Kinney, who sug
gested the problem and supervised the work.  His advice and 
assistance yielded great comfort especially when the going was 
toughest.  Also,  thanks are expressed by the author to the 
members of the Analytical Laboratory for their assistance and 
to his colleagues,  Messieurs,  Del Bel,  Oclcert and Gillmore for 
their kind assurances and confidence  in him.
Thanks are also due to the Davison Chemical  Company, 
Baltimore,  Maryland,  the Hoppers'  Company,  Pittsburgh,  Pennsyl 
vania and the Laclede Gas Light Company,  Saint Louis,  Missouri 
for their generosity in supplying the  various samples employed 
in this  Investigation.
The draftsman,  Mrs. E.  L.  Malloy  and the  typist,  Mrs.
L.  Friedman, were  very helpful in the preparation of this dis
sertation.  They are to he commended for their very great pa
tience with the author.
Finally,  the present investigator wishes to express his 
appreciation to his immediate family.  He is indebted to his 
wife,  who with her good nature,  undertook a greater part of her 
family duties and to his two small children,  who  in their own 
little way,  were  very confident that this work would come  to a 
successful culmination.
