In projecting lantern slides I found that frequently the typewritten
material was too small, and since my return I have arranged with Miss Wilso
to use only capital letters in typing material for slides. By this means
and by the use of carbon paper on the back side of the copy to intensify
the blackness, we have obtained some good results. I think that all the
care given to the preparation of tables is well spent. A few slides in
English, a few in French, and a few in German are desirable. When one is
lecturing to a foreign audience, one can read or translate the titles
and give a moment to the discussion of the column headings. The figures
of course, being in Arabic, are self-explanatory.
In several instances I was able to secure copies of announcements of
my lecture. These announcements are appended herewith.
