to it, KwbVh tfcp solstitial colure, and all 

 efrcies parallel to it. are concentric cir- 

 cles ; all circles oblique to the eye are 

 ellipses ; and all circles, whose planes pass 

 through the eye, straight lines. The use 

 of the instrument is to show the comnu .1 

 astronomical problems, which it does very 

 imperfectly. 



AKALEP'SY, from avaXa^aitia, to re- 

 cover. A species of epileptic attack, of 

 sudden and frequent occurrence, but not 

 reckoned dangerous. 



ANAL'OOY, Gr. a.vaXo'yia, of ctvctXvyos, 

 according to rule. A certain relation or 

 agreement between things in some cir- 

 cumstances or effects, when the things are 

 otherwise entirely different, and which in 

 reasoning serve to explain or illustrate, 

 but not to demonstrate. Thus, there is 

 an analogy between plants and animals, 

 in so far as both grow and decay. In 

 matters of experience analogy is one of 

 the principal bases of reasoning. 



ANALYSIS, Gr. ivoAwr/?, resolution; 

 K. Awn, to loosen. 1. Generally, the reso- 

 lution of something into its constituents : 

 an examination of the different parts of a 

 subject separately, as the propositions of 

 an argument ; opposed to synthesis or com- 

 position. 2. In mathematics, the name 



given to " the method of resolving pro- 

 blems by means of algebraical equa- 

 tions." The analytic method of resolving 

 problems consists in "reasoning upon the 

 whole problem, reducing it at every step 

 to simpler terms, and so coming at last to 

 those considerations which must be put 

 together to make a solution and to verify 

 it." Analysis is divided into finite and 

 infinite, determinate and indeterminate, 

 laid residual. The analysis of finite quan- 

 tities constitutes algebra, and that of infi- 

 nite quantities constitutes the method of 

 flexions, or differential calculus. Analysis 



of powers is evolution. 3. In chemistry, 



the resolution of a compound body to its 

 elements, which is effected by means of 

 heat, mixture, electricity, &c. Qualita- 

 tive analysis consists in the determination 

 of the component parts of a compound 

 merely in respect to their nature, and 

 without reference to their proportions; 

 by quantative analysis, on the other hand, 

 it is required to determine the relative 

 proportions of the component part*. 



ANALY'TICS, the method of analysis. A 

 name given to algobra, as being a general 

 analysis of pure mathematics. 



ANAMORFHO sis, from a>, and [AogQo/ri;, 

 formation. 1. In perspective drau-ing, a pro- 

 jection or representation, which, under 

 ordinary points of view, appears extrava- 

 gantly distorted and ridiculous, yet seen 

 from a particular situation, it strikes the 

 eye. as one of complete symmetry. The 

 anamorphosis is also something restored

by reflection from specula, with certain 

 surfaces as those of cones and cylinders, 

 and by refraction through lenses, tru- 

 ncations of-this sort depend on the simplest 

 rules of mathematics and perspective. 2. 

 In natural history, no. appearance unusual 

 to the production. 



ANA'NAS (Brazilian), the pine-apple 

 plant. A species of bromelia which is a 

 native of South America, but now grows 

 wild in some parts of Africa and Asia, es- 

 pecially the Malayan Archipelago, where 

 it seems to thrive better than in its native 

 woods. 



ANAN'DROUS, from i, without, and av<j , 

 avge;, a male, a stamen. Plants whose 

 flowers are destitute of stamens ; thence 

 called female flowers. 



AN'APEST, \ from aa and xoutu, to beat

ANAPLEHO'SIS (aoirlr,%uirtf). Restora-

ANARRHICH'AS, the sea-wolf, or wolf-fish. 

 A genus of acanthopterygious fish, belong- 

 ing to Cuvier's family Gobiodes. Named 

 from aia, upwards, and $vu, to drag, in 

 allusion to its climbing rocks and shoals 

 by aid of its fins and tail. 



ANARRHIN'TJM, a genus of herbaceous 

 plants of the class didynamia, and order 

 angiotnonospermia. Named from ac-va. and 

 <yo?, the seed vessel being recurvated. 



AN'AS. The anas of Cuvier is a genus of 

 palmipedes, of the family Lamellirostres,

 the cygnus (swan), the anser (goose), and 

 the ANAS of Meyer, the duck, properly so 

 called, of which there are many species. 

 Name from cwctv, to swim well. 



ANASAR'CA, from a, between, and

 consists in a collection of serous fluid in 

 the cellular membrane, immediately under 

 the skin. 



ANASTO'MA., a subgenus of land- volute 

 shells (lucernin<e), belonging to the genus 

 lucerna. Name from , upwards, and

ANASTOMO'SE, from avo and rroiut, the 

 mouth. To inosculate : the term is used
