LAW 



L., Hook and Gravesande's, of Elasticity, 

 that the tension is directly proportionate to the length 

 of , ctended, and to the amount "i the extend- 



.ind that it is also inversely proportionate 

 to the d ofthe extended body. L., Huxley's, 



t l lL . eren > bei ween man and the higher 



ss marked than those between the higher 

 lower apes. L., Joule's, the heating-power 

 rtional to the product "I the resist- 

 square ol the current-strength, and the time the 

 current flows. L., Kirchhoff's, in electricity : i. The 

 sum of all thepositive i urrents is equal to the sum of all 

 the negative currents, and, hence, if we add these, the 

 2. I he sum of all the electromotive 

 s in any circuit is equal to the sum of all the 

 products obtained by multiplying the separate currents 

 by | tances through which they are (lowing. 



i. In optics, the law that a transparent body absorbs 

 of light passing through it those rays which 

 it emits in the incandescent state. See L., Angstrdn? -. 

 L., Kofacker-Sadler's, a law as to the cause of the 

 differenci From a study of 80,000 cases these

 wife there an- a- many boysas girls; if both are of 

 the sam re are 1029 boys to 1000 girls; if the 



husband is older, 1057 hoy-, toiooogirls. L., Kopp's 

 ■ 1, the addition of CH 2 to members of 

 in homologous series of chemic compounds 

 raises the l«>iling-point about IQ.5 C. L., Lenz's, 

 the law in eltctro-magnetic induction that the direction 

 of induced currents is such that their reaction arre-ts 

 the motion that produce.-, them. L., Levert's, that 

 in placenta prsevia there is a marginal insertion of the 

 cord. L., Listing's, pertain-, to the movements of the 

 eye-ball: when moved from the position of rest, the 

 angle of rotation in the second position is the same as 

 if the eye were turned about a fixed axi- perpendicular 

 to the first and second positions of the visual line. 

 L., Louis', in adults the lungs usually contain 

 tubercle when it is present elsewhere in the body. L., 

 Magnus's, in thermo-electrii ity, the law that " in cir- 

 cuit- of the same metal throughout, no electromotive 

 force is produced by variation in temperature or of 

 section ofthe conductor at different parts ofthe circuit." 

 L., Malaguti's, when two salts are mixed in solution 

 double decomposition occurs and tour salts are formed 

 . the proportions of each depending on the 

 ngth of union of the respective basic and acid 

 radicles. L., Mariotte's, the law of physics that 

 the volume of a gas varies inversely as the pressure to 

 which it is subjected See /.., Boyle's. L. of 

 Molecular Weights, the molecular weight of an 

 menl is twice its atomic weight (with the exception 

 of 1 1.' and 1 d ) ; the molecular weight of a compound is 

 ii! the sum of the atomic weights of its 

 L. of Multiple Proportions, that two 

 uniting to form a series of chemic com- 

 tnds, do so in proportions that are simple multiples 

 ol one another or of one common proportion. L., 

 Newton's, the unit force is thai force which, acting 

 tor unit 1 1 me on the unit mass, produces unit velocity. 

 L., Ohm's, the law that the current strength varies 

 dii tromotive force, and inversely as the 



It is usually expressed by the formula 



. in which C is the current in amperes; E, 



1 > 



the electromotive force in volts; R, the resistance of 

 the . that of the internal part of the 



nit, in ohms. L. of Organic Balance, exces- 

 ■ opment of one pari n organism is coun- 



tei by deficient growth of another part. L.,
