ANASTATICA. 
again, if the percentic weights of the different 
ingredients be simple multiples of their atomic 
weights, it affords a strong probability that the 
substance analyzed is no mechanical mixture but 
a true chemical compound. It therefore becomes 
desirable to find the number of atoms which cor- 
responds to the percentage result of our analysis, 
and therefrom, if possible, to establish a chemical 
formula. This is done by dividing the percent- 
age numbers by the atomic weights of the re- 
spective ingredients. The numbers thus ob- 
tained, express the relative number of atoms of 
the different ingredients; and in order to reduce 
them to small, and, if possible, whole numbers, 
the smallest may be made unity, and divided re- 
spectively into all the rest. How the number of 
atoms thus found is to be distributed, for the 
purpose of bringing it into a formula, in confor- 
mity with other similar combinations, depends 
entirely on theoretical views. 
In regard to the history of analytical chemis- 
try, its progress has, as might be supposed, been 
inseparably connected with that of the science of 
chemistry itself. Bergman, Scheele, Klaproth, 
and others, improved the analytical methods con- 
siderably, but it was only after the development, 
by Richter, of the doctrine of the fixed propor- 
tions in which substances combine, that it was 
elevated to the rank of a science. It is, in a 
great measure, to the unremitting labours of Ber- 
zelius, and his accurate determination of the fun- 
damental or combining numbers, that it is in- 
debted to its present perfection. The ultimate 
analysis of organic bodies is also indebted, for its 
present perfection, to the improvements of Liebig 
and several others. 
ANASTATICA,—popularly Rose of Jericho. A 
small, perennial, hardy herbaceous plant, of the 
cruciferous order, from the Levant. It grows to 
the height of only six inches, divides into many 
irregular branches near the root, sends out from 
each joint a single, oblong, hoary leaf; and pro- 
duces from June to August small, single, whitish- 
This plant, after be- 
ing gathered and thoroughly dried, has the curious 
property of recovering its original form upon im- 
mersion in water. It was superstitiously believed 
_by the monks of the dark ages to open its flowers 
in the anniversary of the night of our Lord’s in- 
carnation, and in consequence was called by them 
Rosa Marie; and it is still superstitiously be- 
liéved by many of the lower orders in Great Bri- 
tain to possess the property, if placed in water at 
the time when a woman’s labour commences, of 
expanding at the precise moment of her giving 
birth to her infant. It grows wild in the sandy 
deserts of Arabia and Palestine; and is there 
designated by a name which signifies ‘ Mary’s 
hand.’ 
ANATOMY OF ANIMALS. The study of the 
structure, composition, mutual connection, and 
respective situation of the members and organs 
of animals, by means of the dissection of their

carcass, and the ocular examination of cuts and 
openings made by the knife. The anatomical 
structure of the principal domesticated animals, 
and an outline of the anatomical structure of 
man, are taught in veterinary schools; and a 
knowledge of both, particularly as illustrating 
each other, is of much value to the farmer, in 
regulating his treatment of the numerous domes- 
tic animals of the farm. When he is acquainted 
with the organism of their bodies, and with the | 
functions which their several organs perform, he 
can usually adapt both the kind and quantity of 
their food to the peculiarities of their constitu- 
tion, and frequently avert or overcome their ten-. 
dencies to disease; and when he knows the 
identity in some points, and the similarity in 
others, between their animal sensations and his 
own, he will have a degree of concern for their 
well-being, of comprehension of their wants, and 
of sympathy for their ailments, far greater than 
he would otherwise possess, and most beneficial 
in effect upon both his moral character and his 
worldly prosperity. Any farmers who have not 
enjoyed access to veterinary schools, ought to 
employ some early leisure in picking up a little 
knowledge of animal anatomy from books. Ana- 
tomical articles on all the principal organs of 
animals will be found in their respective places 
in our work. 
ANATOMY OF VEGETABLES. The study 
of the structure of vegetables by sectional cutting 
with the knife. This study is the true basis of 
the science of vegetable physiology, and of all 
true knowledge of the constitution and functions 
of plants; and, though not personally prosecuted, 
yet ought to be known in its results or discoy- 
eries, by every gardener and farmer. The earliest 
writings of any value on vegetable anatomy, were 
the Anatomy of Plants, by the English physician 
Grew, published in 1682; and portions of the 
Opera Omnia of the Italian physician Malpighi, | 
published in 1687; but treatises and articles of 
greater or less length, and aggregately of the 
most minute research and a very high order of 
excellence, have been written by almost all of the 
numerous subsequent distinguished physiologists. 
The several parts and organs of plants, as dis- 
covered and examined by dissection, will be found 
described in their respective places in our work. 
ANBURY. A kind of wen, or spongy wart or 
tumour on the legs or flanks of the horse. It is 
usually full of blood; and may be removed either 
by the fastening of a ligature round its base till 
it dies away, or by the application first of the 
knife and next of some caustic substance such as 
a solution of blue vitriol, to destroy its connec- 
tion with the absorbent vessels. Taplin recom- 
mends that it should be carefully anointed once 
in three or four days with the butyr of antimony, 
which, he says, will effectually cure the disease. 
ANBURY, Ampury, or Hansury. A perplex- 
ing, stubborn, and desolating disease in turnips. 
It takes the name of anbury from its early de-
