The teacher of spherical trigonometry and solid geometry will find the simple quadrant compasses illustrated in Figure 1 a convenient device for drawing circles on a blackened globe. It is easy to use and makes it possible to obtain results that are more uniform than free-hand drawings.

These interesting situations in which generics play a key role in interactional pragmatics sparked my memory of solid geometry and spherical trigonometry class at Stuyvesant High School in the early 1960s. Each morning our instructor, the somewhat irascible Mr. Burns, would start off by asking a question on the day's material, calling for a response by ‘[student surname]’. Stuyvesant, in those days an all-male institution, functioned, like prep schools, on a surname basis for both reference and address; the teachers’ names were prefaced by Mr. or Mrs. or Miss, while student names had no prefixed title.

I am grateful to both Dr Ponsonby and Sqn Ldr Hoare for their responses to my original article and would like to thank them for replying. It is interesting that they have come up with such different approaches, one based on solid geometry (but not spherical trigonometry) and the other based on a map projection, which both give exact or near-exact answers.

Elementary algebra, plane geometry, intermediate algebra, plane and spherical trigonometry, solid geometry, and advanced algebra are all being studied in the same room at the same time. Sounds something like a one-room country school, doesn't it? This is being done by a group of mentally superior pupils in two ungraded classes (taught by the writer) at Monroe High School.

Second Year

In second year algebra courses students are normally introduced to the conic sections by being told that certain curves which may be represented by quadratic equations in two unknowns are, in fact, equations of conic sections. In solid geometry the same students are told that a section of a right circular cone made by a plane is a conic section. Various kinds of models are occasionally employed to illustrate what the conic sections look like in the geometric sense, but ordinarily little effort is made to tie up the fact that a relation exists between the introduction given in algebra and the models presented in solid geometry.

School Subjects

At the present time it is generally assumed that the motion picture film can be used to good advantage in teaching the units in the various school subjects. It is, therefore, natural that the teacher of mathematics is led to inquire regarding films which could be so used in the mathematics classroom. The first source for such information is no doubt the latest edition of the Educational Film Catalog.1 In the 1939 edition only three films were listed under the heading Mathematics and one of these, “Visualized Solid Geometry,” was withdrawn from circulation early this year. A second source for the teacher may be found in the catalogues published by the various distributors, copies of which are no doubt on file in the office of the principal or the head of the visual aids department of the local school system. Over half of the state universities have established extension divisions for the distribution of these films and a list of these is found in the Educational Film Catalog as well as at the close of this article. In addition there are a number of private distributors with offices in many of the principal cities.
