explanation. The special telegrams will contain that information which experi- 

 ence has shown to be especially valuable. Whenever possible, these telegrams 

 will be in cipher according to the Science Observer Code, a cipher language de- 

 vised to les:;en the number of words and to render the message less liable to muti- 

 lation and misunderstanding. To those persons who do not possess the code, 

 the telegrams will be sent in ordinary manner, but abbreviated according to the 

 following form : 



Telegram. — Comet Swift eleventh May fifteen six ascension zero fifty-nine 

 north fourteen thirty-six plus six south four tenth. 



Translation. — Comet discovered by Swift, May iid. i5h. 6m., Washing- 

 ton Mean Time, in R. A. oh. 59m., Declination -|- 14° 36'. Daily motion, R. 

 A. -}- 6m., Declination — 4'. Tenth magnitude. 



The date will be expressed by the name of the month, preceded by an ordi- 

 nal number giving the day of the month, and followed by two numbers express- 

 ing the hour and minute in Washington Mean Time (civil). Right ascension 

 will be given in hours and minutes, preceded by the word "ascension." Decli- 

 nation will be given in degrees and minutes, preceded by the word " north" or 

 "south." Daily motion in R. A. will be ^iven in minutes of time, preceded by 

 the word "plus" or "minus," and in declination in minutes of arc, preceded 

 by the word " north " or " south ", 



Magnitude will be expressed by an ordinal number. 



The actual expense of sending the telegrams will be borne by the persons 

 receiving them, though, for convenience, the charges will be prepaid and annual 

 accounts sent to the subscribers. 



Mr. Ritchie has already had considerable experience in this kind of work 

 while sending the Special Circulars of the Science Observer ; and his success in 

 this almost guarantees the success of the larger undertaking.

INDUCTION IN SCIENCE. 



PROF. H. S. S. SMITH. 



The scientific method, as usually understood, is the method of induction. 

 By it the statement of a law of action is formulated from a knowledge of many 

 facts that bear on the subject. The progress of science clearly shows that the 

 principles of induction may be used in two ways and we may call them, for con- 

 venience, quahtative induction and quantitative induction. In many respects 

 they differ widely from one another. The qualitative is essentially metaphysical 

 in its manner of procedure and as such, in many instances, produces naught bu t
