The letters of instruction are based on the lectures of the
Mining Academy. In addition to the presentation of the
material they bring seminars (= practical exercises) with
questions for repetition and exercises as well as the an-
swers and solutions belonging to them. In this form they
are especially qualified for self-study. In their totality
they impart the knowledge that is expected of a graduat-
ed engineer of the mining and smelting branches. Beyond
the circle of home=students the letters of instruction will
also be of interest to the students of the Mining Academy,
to technical. high schools, and universities as well as to
engineers at work.
Each letter of instruction contains about 64 pages and costs 2,- DM
inasmuch as nothing else has been noted.
All the letters of instruction mentioned in this prospectus are written
in the German language.
Interested persons outside the German Democratic Republic (Deutsche
Demokratische Republik) can obtain them through any good bookshop.
The booksellers are kindly asked to send their.orders, with the noted
order-number, to Deutscher Budh-Export and Import, Leipzig C1

latibn with complex numbers shall be dealt with. The series of
letters will lead up to multiple integrals together with their appli-
cations and up to the fundamentals and the most important solu-
tion methods of common differential equations.

Spherical Trigonometry with its Uses
6 letters of instruction (complete; price of the 6th letter 4,- DM)
The series of letters of instruction-spherical trigonometry with its
uses in mathematical geography, astronomy, and mining-treats
in a clear and intelligible manner by means of many illustrations
and exercises calculating and designing geometry on the sphere
including its practical use in the working field of the miner, mine
surveyor, surveying engineer, cartographer (drawings of maps!),
mineralogist, etc.
The sixth letter deals with spherical astronomy using the ,Nau-
tisches Jahrbuch" in the new form, which was introduced in 1953.
The application of modern methods and the special consideration
of educational-didactic points of view qualify the letters of in-
struction not only for self-study, but also as text-book and exer-
cise-book for spherical trigonometry in all kinds of schools. They
thus fill up a gap; for there exists a striking deficiency of newer
text-books in spherical trigonometry.

Differentialgeometrie in vektorieller Behandlung
Differential Geometry in Vectorial Treatment
1st letter: Differential Geometry of Space Curves (has been published;
price 2,50 DM)
2nd letter: Differential Geometry of Surfaces
The letters of instruction are to give in the shortest possible way
the fundamental knowledge of differential geometry necessary for
the young mine surveyor or professional surveyor. For that pur-
pose the vector system has proved to be not only the shortest
method, suitable to the object, but it will also, with didactically
skilful treatment, most readily become clear to the scholar.
The first letter of instruction especially deals with the moving
tripod and the formulas of Frenet. The second letter of instruction
treats among others the parametric representation of a surface,
the surface curves, and the fundamental forms of the theory of
surfaces.

Exercises for the Analytic Geometry of the Plane
1 letter of instruction (complete)
The exercises for the analytic geometry of the plane serve as
preparation for the series of letters of instruction -Analytic
Geometry (of space)-.
The letter of instruction follows the small text-book of Crantz-
Hauptmann -Analytic Geometry of the Plane- (Teubner publishing
house), but can also be used independently of it. The complete solu-
tions of the exercises have been given because, according to ex-
perience, the giving of the results does not, for self-study, suffice
to help to discover the own mistakes on self-checking.
The collection of exercises that is based on practical experiences
of many years should also be a help to teachers of mathematics at
technical and high schools.

General Blowpipe Analysis
1 letter of instruction (complete)
The student will be acquainted with the implements and the tech-
nique of blowpipe analysis. In well over 100 experiments he prac-
tises the work on charcoal, in the flask, in a glass tube closed at
one end and becomes acquainted with the fusibility of the speci-
mens, the colouring of the flames, the behaviour in the borax and
microcosmic salt, with soda, cobalt-solution, and potassium hydro-
sulphate.
The experiments have been so chosen that, after their carrying-out,
the student will possess a realizable dexterity in the determination
of minerals and will have enlarged his mineralogical knowledge.

Spezielle Lotrohrprobierkunde
Special Blowpipe Analysis
In preparation 4 letters of instruction, of which 1 and 2 have been
published; the price of the 2nd letter is 2,50 DM
In the first letter .is shown how a qualitative analysis of this dealt
with group I, the alkali, alkaline earth, and metallic salts, is to
be carried out. Through 55 characteristic and fully explained
examples the student is shown what he has to pay attention to
and how he finally comes to the perception and conclusion that
the examined substance, that was at first quite unknown to him,
can only be the mineral that is named at the end of the test.
In the following letters of instruction are dealt with, in a few
detailed examples, the following groups: II metallic oxides, III sili-
cates and aluminates, IV sulphurets and arsenic compounds, selenic
and telluric compounds and V metal alloys which do not contain
any arsenic nor sulphur, or which contain only traces of theft.
