It is a very remarkable fact that not only are such substances as albumin, gluten, fibrin, and syntonin, known exclusively as products of animal and vegetable bodies, but that every animal and every plant, at all periods of its existence, contains one or other of them, though, in other respects, the composition of living bodies may vary indefinitely. Thus, some plants contain neither starch nor cellulose, while these substances are found in some animals; while many animals contain no horny matter and no gelatin-yielding substance. So that the matter which appears to be the essential foundation of both the animal and the plant is the proteid united with water; though it is probable that, in all animals and plants, these are associated with more or less fatty and amyloid (or starchy and saccharine) substances, and with very small quantities of certain mineral bodies, of which the most important appear to be phosphorus, iron, lime, and potash.
I left Tarma on January 29th, following a well-cultivated valley, fairly thickly inhabited. We were travelling over a good mule-track, swarming with Indians, donkeys, mules, and horses. The mud houses and land on either side were enclosed by hedges of cacti, or by walls. We were between barren mountains of a brownish colour, against which the quaint, brightly-coloured costumes of the many people on the road were thrown out in vivid contrast. Most of the houses were constructed of large mud bricks, sun-dried. The crops seemed to consist chiefly of Indian corn. As we went farther, among dark brown rocks and limestone, we came to grottoes and rock habitations. At some remote period there must have been a great upheaval in that country--at least, judging by the sedimentary foliated rock, the strata of which were from one to three feet thick, and which had originally been deposited horizontally by water. These accumulations or sediments now stood up at an angle of 45 deg.. We were now in a region where llamas were plentiful--most delightful animals, with their pointed ears pricked up, their luxuriant coats, and stumpy curled tails.
