The image shows three architectural drawings or sketches of different types of grottos or baths. Each drawing is labeled with a title and a plate number. The style of the drawings is reminiscent of 18th or 19th-century architectural illustrations. **Left:** The drawing is titled "Grotesque, or Rural Bath." It depicts a rustic, stone structure covered in foliage and vines. The structure appears to be a small, open-air bath or grotto with a rough, naturalistic design. Below the drawing is a circular diagram with radial lines and measurements, possibly representing a section or detail of the structure. **Center:** The drawing is titled "Modern Grotto." It shows a more formal, symmetrical structure with a classical facade. The drawing includes a perspective view of the exterior, a cross-section showing the interior, and a plan view of the layout. The interior features a vaulted ceiling, columns, and a staircase. The plan view shows an oval-shaped structure with various rooms and corridors. **Right:** The drawing is titled "Gothic Grotto." It depicts a small, pointed-arch structure with a Gothic-style window. The structure appears to be a secluded, cave-like grotto with a rough stone exterior. Below the drawing is a plan view of the structure, showing a complex, irregular layout with multiple rooms and corridors. The plan view includes measurements in feet and inches.
