His head they took, but could not turn his heart ; 

 And thus it is, apostates are abhorred 

 By living man, and scorned by the undying God. 

 His death brought shame on the Muhammedan, 

 Though his soul went to everlasting bliss. 

 Dear is thy memory, Tegh Bahadur ! 

 Earth mourn' d its separation from thee, 

 And heaven welcomed thee with shouts of joy.

 India.— By G. Buist, LL. D„ F. R. S., L. & C., F. G. S. fyc. 



One of the greatest desiderata with travellers, is to be able to obtain 

 an instrument for measuring elevations, of moderate size, considerable 

 portability and immunity from injuries from the accidents apt to be 

 encountered in journeying through new countries ; a great degree of 

 nicety or exactitude is rarely attainable on a first visit, and is willingly 

 dispensed with in comparison to tolerable approximations when only 

 attainable at the expense of much outlay, trouble and loss of time. The 

 mountain barometer can be made tolerably portable so far as size and 

 weight are concerned, but is in its strongest and most efficient form so 

 extremely liable to accidents, so expensive, and so difficult in India to 

 get repaired or replaced that few travellers in the East care to be en- 

 cumbered with it at all. The Mountain Thermometer has done excel- 

 lent barometric service in India ; but it has seldom happened that 

 instruments, cut finer than fifths of a degree, have been made use of — 

 at moderate altitudes one degree corresponds with five hundred feet of 

 elevation, so that even when degrees are cut to tenths, the smallest 

 division will not indicate less than fifty feet. A good barometer read-
