 See under Cabalistic. T., Chemicoradical, accord- 

 ing to which the object of organic chemistry was the 

 investigation and isolation of radicles in the sense of 

 the dualistic theory, as the more intimate components 

 of the organic compounds, by which means it was 

 sought to explain the constitution of the latter. This 

 theory flourished in Germany simultaneously with the 

 electrochemic theory (a. v.) (Richter). T., Clark's, 

 of the pathology of asthma : That the asthma is 

 caused by a swelling of the bronchial mucous mem- 

 brane, due to relaxation of the vessels from vaso- 

 motor nerve causes. The swelling, according to 

 Clark, has the character of urticaria wheals and is in 

 a sense similar to that occurring in the erectile tissue 

 of the nasal mucosa in hay- asthma. T. of Color,

 T., Early- Type, of Dumas, according to which sub- 

 stances were considered to have the same chemic 

 type, to be of the same species when they possessed 

 like fundamental properties, e. g., acetic and chlor- 

 acetic acids ; or, as held by Regnault, they were re- 

 garded as of the same mechanical type, belonging to 



the same natural family, when they were related in 

 structure, but manifested different chemical characters ; 

 alcohol and acetic acid. (Richter.) T., Ehrlich's 

 Side-chain. See under Immunity and Lateral 

 Chain. T., Electrochemic, according to which 

 every chemic compound is composed of two groups, 

 electrically different, and these are further made up of 

 two different groups of elements. Thus salts were 

 regarded as combinations of electropositive bases 

 (metallic oxid) with electronegative acids (acid an- 

 hydrids), and these in turn were held to be binary 

 compounds of oxygen with metals and nonmetals. 

 This theory prevailed in Germany until about i860, 

 but was superseded by the unitary theory. (Richter.)

 ment but a symptom, and that nerve disturbances

 Coronary. T., Lateral-chain, of Ehrlich. See 

 Lateral-chain. T., Leyden's, of the pathology of 

 asthma : That the asthma is due to the presence of 

 the crystals discovered by Leyden, the sharp ends 

 of which are supposed to stimulate the terminations 

 of the vagus. T. of Life, Roeschlaub's Excite-

 T., Powell's, that the displacement of the heart and 

 other organs in pleural effusion is due to the traction 

 of the elastic lung on the healthy side. T., Rib- 

 bert's. See Ribbert and under Tuberctdosis. T., 

 Schapringer's, that traumatic enophthalmos may have 

 its origin in the paralysis of Miiller's orbital muscledue 

 to some lesion of the sympathetic. T., Schenk's, that 

 it is possible to govern the process of gestation so as to 

 determine the sex of human offspring : " When no 

 sugar is secreted, not even the smallest quantity, then 

 the ovum will be developed which is qualified to be- 

 come a male child." T., Spherular, of Kunstler, 

 according to which the protoplasm of the flagellatae is 

 built up as cells build up cellular tissue by numerous 

 protoplasmic spherules ( " spherules protoplasmiques ' ' ) 

 placed in close apposition to one another. Every 

 such protoplasmic spherule is supposed to consist of 

 an external dense and firm wall with fluid contents ; 

 therefore properly speaking a vesicle. In consequence 

 of this structure, protoplasm frequently appears to be 

 composed of closely packed vacuoles of the minutest 

 size, separated inter se by very delicate partitions of a 

 denser nature. T., Symmer's, of Electricity, it as- 

 sumes the existence of two electric fluids and explains 

 all electric phenomena by the assumption that an 

 attraction takes place between the molecules of these 

 electric fluids and the molecules of matter, similar 

 electric molecules repelling each other, dissimilar ones 

 attracting each other, but in both cases dragging 

 awav with them the molecules of matter. It has 

 been abandoned by electricians, though retained by 

 writers on medical electricity. [Jacoby.] T., Type, 

 of Gerhardt (1853), the culmination of the "type" 

 idea, an amalgamation of the early type or substitu- 

 tion theory of Dumas and Laurent with the radical 

 theory of Berzelius and Liebig. The molecule was its 

 basis, and to it was attached a more extended group- 

 ing of the atoms in the molecule. The types of Ger- 

 hardt were chemic types. He included the type
