A hydraulic press which uses a hydraulic cylinder to generate force. The inventor of the device, Joseph Bramah, had also developed the flush toilet and studied the motion of the fluids in the toilet and developed the press to test it. O is a lever, which forces down piston a upon the water in cylinder A. The water goes through tube d into the cylinder where piston C works, causing it to rise which lifts platform K and compresses bales.

A complex anatomical view of the heart. RA is the right atrium, or auricle, which receives the deoxygenated blood by way of two superior vena cava (SVC) and one inferior vena cava (IVC). The blood passes through the right ventricle (RV) and is pumped up to the lungs via the pulmonary arteries (PA). At the lungs, the blood is reoxygenated and returns via the pulmonary vein (PV) and left atrium/auricle (LA). From there, the blood is passed to the left ventricle (LV) where the blood is pumped up through the systematic arch (SA) to the body. The systematic arch gives off a right innominate artery (INN), where the blood is then passed to the right and left carotid (C) and subclavian (SCL), where the blood goes to the head and arms respectively. It continues dorsally to the dorsal aorta (DA), which is the main artery that distributes blood to the whole body. TR is the windpipe, or trachea, BR is the bronchial tube that carries air to the lungs, and BV is a blood vessel on the wall of the heart.

Crystal; If the alternate planes of the hexoctahedron extend until the intersect, a new for will result. This form, the Pentagonal Icositetrahedron, is bounded by twenty-four similar but unsymmetrical sides. Naumann's symbol for this form is (m0n/2)r, y{lkh}; Miller's is (m0n/2)l, y{klh}; h>k>l. This form is known as 'right-handed' because it contains the right, top plane of the front, upper octant.
