y is, i.cat ed of the determination of Zn com-
pounds in the products of.phase analysis with the aid of the am-
perometric titration of Zn with a solution of ferrocya-nide, with
a Pt anode. The titrakion is carried out in an ammonium-.acetate
medium in the Oresence lot Pb, Cu, and small quantities of Fe.
Cu is combined into an ammoniacal and Pb into an acetate com-
pound. Fe oxide is quantitatively precipitated in the form of the
hydroxide (basic salt) which does not react with the ferrocyanide.
If Fe is present'in, large amounts, the titration is carried out in
an ammonium citrate medium wherein Fe is combined into a

TITLEs Entombment of a Pelycosaur on the Pinega River (zakhoroneniye peli-..

PERIODICALS Doklady AN SSSIR, 1957, Vol. 116, Nr 5, PP. 859 862 (USSR)
ABSTRACTs In 1955 reptile relics were discoveredin the investigation of
Permian Old Red in the region of Arkhangellsk. Theyweredetermined
as up to now unknown pelycolsaur - caseides from the USSR, an d are
similar to such of lower Permian of North America. The site lies
7 km below the.villagq of Karpogory, opposite the upper part of the
village of Moroznitea. The cross section found in the excavations
is described indetaill. The bones were found in the layers 7 - 9-
They are-the.followings 7) Arenaceous reddish-brown loams, solid,
partly fine-stratified. The occurrence of the bones is bound to
intermediate layers of brown-gray and dark gray tough loam. 8) Yel-
low-brown aleurolites# fine-stratified, with few bone splinters .
i 9)'Reddish-brown sandstones, fine-grained, with very few bone splin-
. ters. The rock which contains the bones is described in detail.
The bones are usually grayish-yellowg of-ten almost black. The main
Card 1/4 part of the bones belongs to great individuals. Only one 1:art of

a jaw,-of the half size, is assumed to'have belonged to a young
animal Further bones of the same kind were found in a ditance of
circa ;o m westwards from the main site, together with not well
conserved bone relicsi apparently of small cotylesaurs. The animal
relics were apparently simultaneously transferred, macerated, and
weathered. Only few bones are considerably worse conserved and to
a greater-extent grinded off. Either the animals died earlier or
their bones have suffered a longer transport. One can assume that
the formation of dark pelits sediments was effected by a temporary
.regime alteration ofthe waters. It is possible that the swamp-
-lake sediments of a lower coastal plain, where the pelycobaurs
,lived, were eroded. In any case-also the cadavers of the animals
were swept away beside the surface loam- and mud sediments rich in
organic substances. According to a report of M. A. Plotnikov this
site belongs to the upper part of the Nizhne-Ustlye aleurolites
and is a parated from the marine Kazan' sediments lying below by a
.mass of a thickness of more than 30 m. Then the question of the
age of the concerning layers iG discuseed, The author agreas to the
above-mentioned assumption of Plotnikov. He does not doubt that
the terrestrial fauna in the north of the plate did not occur at
Card 2/4 the end of the first half of the Tartarian time (Suchona period),

but already much earlier. The taseide find of Pinega can be brough t
in close connection with the only captoridde find on the Wyatka
river in the Kirov,region. The caseides of Pinega and the captorini-
des of Vyatka are probably late representatives of this group which
formerly was so.manifold. Obviously their rareness is not a chance
one, but due totheir rareness in the total complex of the fauna
of the Jj4d zone. If the age of the Pinega finds is estimated the
relics of the edaphosaurian terapsib phreatosuchides from the
copper containing sandstones of.Bashkiria have to be taken into
account. Therefore the statement.of Ye. M. Lyutkevich-that terre-
strial vertebrates lack in the Kazan' sediments which:are charac-
terized by a marine fauna is not right. The mithor counts the
find of Pinega to the Jjna zone. There are 8 references, all of
which are Slavic.

ABSTRACT- The dependence of the lift coefficient of a hydrofoil upon the parame-
ters characterizing the shape of the profile and its position relative
to the surface of the liquid and the impinging flow which is parallel
to said surface i.s worked out. The following assumptions are made:,
(a) The profile is thin. and cambered only slightly, (b) the flow over
the profileis smooth, (c) the angle of attack is small, (d) the
pressure distributions- along the top and bottom surfaces are inde-.
pendent of one.another, (e) the pressure distribution along the
bottom surface of the hydrofoil is independent of the depth of sub-
mersion. ~ These assumptions enable the author to obtain an approx-
imate expression for the lift coefficient of an infinite-span hydro-.

representation is obtained which is similar to the flow around a biplane profile.
By the application of the impulse theorem And, the energy theorem the author
works out an expression for the lift'of the hydrofoil and the angle of downwash of
the flow in terms of the added'mass of the biplane. On the basis of the symmetry
of the flow relative to the free surface this mass is considered to, be. equal to the
added mass ( X) of a single...plate that is'submerged at twice the depth relative to

ABSTRACT: The paper suggests-a method of calculating the induced drag of 'a- cavi
tating wing. The author.,applieg Prandtl's scheme in which the motio
of the fluid in planes' perpendicular to the direction of the flight is con.-
sidered as coinciding-with the plane-parallel flows generated by the
symmetrical translational motion of the foil. The author uses the
coefficients 6f,the 'added mass of the foil in this motion and calculates
the velocities produced by means -of the application of the momentum
~theorern andAhe energy theorem. The impulse losses and energy
losses in this case are disregarded. Under the above-mentioned con-
ditions the relationships between the lifting force, the induced drag,
and the resulting velocities coincide with the usual relationships of the

For high-speed vessels (Fn tb 0.10 - 0.15, where R- v/V -gL' Fr
is Frud',s number) where the'wave.resistan~e begins to attain consid-
erable value, the relationship stated is inexact and, therefore, it
is'proposed to changethe constant power-index of vs to a variable
dependent on the value of v - leaving unchanged in consequence the
simplicity of the structural9dependence.of the admiralty coeffici-
ent on tonnage, power and 'velocity of motion. On the basis of.the
form of the expression of the power,;.index of vs, the well-known
dependence of power on the towing resistance R, N =: Rv/751 is used.
Hence the coefficient. of resistance is equal to the sum of the fol-
lowing coefficients of resistance; frictional, residual, roughness,
projecting-parts, and air. The last three coefficients are consid-
ered to be independent of thevelocity of motion and are taken to
be identical for geometrically similar vessels. After a series of
simplifying assumptions a new formula is proposed instead of the
admiralty coefficient. In conclusion 9 a numerical example is con-
sidered on determination of the power of the principal motor and
the tonnage of an auxiliary vessel of the fishing fleet, using both
