Democratic Republic, reviewed recent de- 
velopments in the Jena Instrument System 
for biostereometrics. Emphasis was placed 
on the cameras, e.g., the UMK 10/1318, and 
suggestions for new applications were given. 
Session II, presided over by Prof. A. K. Tor- 
legärd, Royal Institute of Technology, Stock- 
holm, Sweden, included two further papers 
on biostereometric systems and six papers 
on cranio-facial morphology. 
Dr. J. Hôhle, Wild Heerbrugg Instruments, 
N.Y., described how the Wild P31, P32 and 
C40 cameras and widely available aerial 
mapping instruments can be used for bios- 
tereometric purposes. 
J.E. Hugg, Baylor College of Medicine, 
Houston, USA, outlined a procedure for 
simultaneous recording of front and rear 
stereopairs of a standing human subject and 
the associated use of conventional plotting 
techniques. 
I. Newton, University of Newcastle upon 
Tyne, England, described an investigation of 
several different techniques of posing the 
head for studies of facial change. The ac- 
curacies of the various systems were re- 
viewed and compared. 
Dr. E.J. Lovesey, Royal Air Force, 
Farnborough, England, described the de- 
velopment of a projected grid (light-slit) sys- 
tem of photogrammetry for use in an- 
thropometric studies such as the measure- 
ment of facial form. 
A.M. Wright, Hospital for Sick Children, 
Toronto, Canada, in a paper co-authored by 
H.U. Lichtenberg and R. Moore, described 
various uses of stereometric data (including 
the production of physical models) for plan- 
ning surgical reconstruction of congenital fa- 
cial deformities. 
K.B. Atkinson, University College, Lon- 
don, in a paper co-authored by I. Newton and 
B.D.G. Morgan, examined the relationships 
between prosthesis content and volume de- 
termination in a case of breast reconstructive 
surgery. 
I.J. Dowman, University College London, 
in a paper co-authored by A.R. Elkington, 
reported on a feasibility study involving the 
use of photogrammetry to measure glaucoma 
development in the human retina. 
Prof. K. Torlegard, Royal Institute of 
Technology, Stockholm, in a paper co- 
authored by C.E.T. Krakau, compared the use 
of a light-slit method with stereophotogram- 
metry for measuring volume of a normal optic 
disc. 
Session III, with Dr. V.R. Kratky, National 
Research Council, Ottawa, Canada, presid- 
PHOTOGRAMMETRIC ENGINEERING & REMOTE SENSING, 1976 
ing, comprised seven further papers on 
cranio-facial morphology. 
Dr. Bernard Schwartz, Tufts University 
School of Medicine, Boston, USA, in a paper 
co-authored by Dr. R.E. Herron and Prof. J.R. 
Cuzzi, described some of the advantages of 
using stereometric parameters other than 
contour maps for quantifying the geometry of 
the eye and its component structures. 
Dr. V.R. Kratky presented a review paper 
on problems associated with the choice of 
instrumentation and analytic methods for 
ophthalmologic applications of photogram- 
metry. 
Dr. G.L. Portney, University of California, 
Davis, USA, described the use of photo- 
grammetry for measuring three-dimensional 
changes in the optic nerve head cup in nor- 
mal and glaucomatous eyes. 
Dr. B.E. Cohan, University of Michigan, 
Ann Arbor, USA, described preliminary re- 
sults achieved with a system of instrumenta- 
tion for stereometric analysis in ophthalmol- 
ogy. 
Dr. W.W. Bowley, University of Connect- 
cut, Stowe, USA, in a paper co-authored by 
Drs. C. Burstone, H. A. Koenig and R. Siat- 
kowski, described the use of a laser holo- 
graphic system and a finite element tech- 
nique for predicting tooth displacement 
based on a ten-times-sized model. 
Dr. J.E. Bergstróm, Royal Institute of 
Technology, Stockholm, in a paper co- 
authored by Carl-Olaf Jonason, reported on 
the accuracy of a stereophotogrammetric 
method involving a stereomicroscope for 
quantifying gingival topography in vivo. 
Dr. RJ. Forstrom, University of Minnesota, 
Minneapolis, USA, in a paper co-authored by 
F.F. Ahlgren, F.D. Dorman, RJ. Isaacson, 
T.M. Speidel, and A. Erdman, described a 
stereo movie system for stereometric mea- 
surement of human jaw motion. 
Session IV was devoted to spatio- 
temporal (four-dimensional) studies in bio- 
stereometrics. Dr. H. M. Karara, University 
of Illinois, USA, presided. 
V.D. Brandow, University of Illinois, read 
the paper of Dr. M.I. Bullock, University of 
Queensland, St. Lucia, Australia, on the use
