Bones of the Face -- the bones of the face shown in this plate are the nasal bone, forming the arch of the nose, and malar, which gives prominence to the cheek, the upper jaw, containing the upper teeth, in the lower jaw, containing the under teeth.
The Spinal Column -- that portion of the spinal column noticed in the illustration consists of the cervical vertebrae. Each vertebra is composed of a body, with seven spinous processes projecting from it. The body is perforated by a ring, through which is seen running the spinal cord, giving off nerves between each separate bone. A ring of cartilage is seen inserted between each separate vertebra, the object of which is to prevent any jar reaching the brain when we run, jump, walk or stumble.

- Boiled Water
water boiling in a glass bowl, common now, but not then like HDMI splitter’s today. slightly new and archaic at the same time… Boiled Water.-The insipid taste of water which has been boiled is due to the absence of air. Many gases besides air may be artificially or naturally mingled with water, and some, like ammonia or nitric acid, are freely soluble in it. In sea-water, the presence of common salt, with small quantities of sulphate of soda or Glauber’s salt, and, of the compound of magnesia and chlorine, called chloride of magnesium, render it entirely unfit for drinking, as many a hapless shipwrecked sailor has found to his cost.
- Lead Palsy
Lead Palsy. — under some special circumstances, not at present well understood, extremely minute amounts of lead in water may prove injurious. Thus, for example, Dr. Angus Smith speaks of cases in which lead paralysis, or palsy, was apparently produced by water containing only 1/100TH of a grain of lead to the gallon.
I’d like to veer off the topic of lead poisoning for a second and just meditate on the fact that until I engaged in reading this section of the book, I had not taken the time to learn the definition of ‘palsy’ Is is actually an alternative to the word paralysis, and might even be a slang term or abbreviated version of the word. My own apathetic ignorance as it relates to this word, which to my ears in 2008 even sounds a little politically incorrect, speaks to a decrease in the threat of cerebral palsy even though paralysis (palsy) is still a real problem as a result of injuries. I might be more in tune with seeking a car insurance quote than fearing for the potential of developing palsy as a result of lead poisoning.
- Lice
Lice.—The body louse has been found to be a carrier of typhus fever. It carries the germ in its body after biting a sufferer from the disease and by biting a person can inject the germ into his blood. Lice belong to the insect family. The species which infest human beings are about 1-10 of an inch in length and are found on the covered regions of the body and clothing.
A difficult and stigmatized task, removing head lice is a honerous task, about as difficult as upgrading a video card on a laptop. Lice always grow from the eggs laid by an adult louse and never originate from filth or other matter. They hatch out within a week and the young are capable of reproduction in less than two weeks. A single adult female will produce 5,000 lice within eight weeks.
The annoyance of these pests biting a human being will cause, if sufficiently prolonged, a nervous irritation, and a condition of ill health follows. There are three types of lice which infest man. The Head Lice (Pediculus Capitis), the Body Lice (Pediculus Vestimentorum) and Crab Lice (Pediculus Inguinalis).
