MR. barlow's MAGNETICAL DISCOVERIES. 



nPHE emperor of Russia has presented Mr. Barlow, of the 

 -"- Royal Military Academy, (through his excellency Count 

 Lieven,) with a valuable gold watch and rich dress chain, &s a 

 mark of the value which his majesty places upon the magne- 

 tical discoveries of that gentleman, and on their important ap- 

 plication to the improvement and security of navigation. We 

 are glad also to add that the East India Board has followed 

 the example of the Admiralty and Trinity Boards, and pre- 

 sented Mr. Barlow with the sum of two hundred pounds. 

 Mr. Barlow not having availed himself of a patent right for 

 his correcting place, is justly entided to these marks of public 

 acknowledgement. 



IMPORTANT CORRECTION RELATIVE TO THE CURE OF GLAN- 

 DERS. 



We have been informed on good authority that the fit mode 

 of exhibition of the sulphate of copper, as a remedy for the 

 contagious glanders of liorses, (noticed in Phil. Mag. for Sep- 

 tember 1824,) is in a liquid state, and not as usual in a ball : it 

 is supposed the form of a ball occasions the medicine to remain 

 so long in the stomach as to produce mischief from irritation. 



USE OF CROTON TIOLIUM IN VETERINARY MEDICINE. 



It is well known that horses do not easily undergo the ope- 

 ration of purging, and scarcely any cathartic which readily 

 affects the human bowels operates on the brute creature. Aloes 

 alone, or along with calomel, purges the horse. Oil, indeed, is 

 also slightly laxative : but of late an accession has been made 

 by the oil of (Proton Tiglium, revived by Mr. Short. This, 

 in the dose of 15 to 25 drops, works as eflfectually as aloes: 

 l)ut the latest improvement is the exliibition of the dried seeds, 

 or even the husk of the dried seeds after the oil has been ex- 

 pressed, 20 to 30 grains of which answers as well as the oil 

 of Croton. 



The danger from an over-dose is as great from this new 

 drug as from aloes. For a small and weakly horse the dose 

 should be less than above stated. Five grains of the Croton 

 seeds is calculated to l>e equal to about one drachni of aloes
