How to make a camera lucida
The instructions on how to make a camera lucida look very confusing. First of all, the text does not relate to the title, as it describes more the use than the process of building it. The pictures are well-drawn but set in the wrong order and would need more explanation to be completely understandable. An instructional text is supposed to include a list of the required materials, which is missing in this case. Therefore the text is misleading. The real instruction is only one sentence long and does not contain details on how to do the steps. The second part of the text does not use imperative but infinitive and mentions a name without reference. The instructions assume that people already know how the camera is supposed to look in the end. With no background knowledge or imagination it seems hardly possible to build this camera solely following these instructions.
