Theodor Benfey's arrangement is an example of a continuous (spiral) table. First published in 1964, it explicitly showed the location of lanthanides and actinides.The elements form a two-dimensional spiral, starting from hydrogen, and folding their way around two peninsulas, the transition metals, and lanthanides and actinides.
Here is the current progress of locating pictures for the remaining elements without images, and what users can possibly do to help the search. Feel free to add your own findings (remember to sign), or discuss them on this page's talk page. See here for more details. Poor quality images: Nitrogen, Calcium, Barium, Mercury

Sample illustration: Periodic table in the style of a space lemniscate by William Crookes. In a self-published book, Types of Graphic Representation of the Periodic System of the Elements (1957) he listed some 700 images published since 1862, classified under 146 heads. [7]
