operation and effects, and doses of medicines in use amongst 
us more than it has, beyond the walls of the college and, a 
little further on, we added , — “ Nor need he (its author) be 
content with domestic sources of information, but extend 
his researches into the continental systems of veterinary 
pharmacy .” 
“ There are more things in heaven and earth, Horatio, 
Than are dreamt of in your philosophy.” 
Shortly, we hope to be able to show how far such a step out 
of our vernacular provinces of information might or might 
not prove advantageous to us. 
The present (fifth) edition boasts of upwards of 60 pages, 
in addition to the number possessed by the former (fourth) 
edition ; which augmentation of space has enabled its author 
to make the following fresh introductions, besides giving new 
formulae to several former preparations. Among the former, 
we may enumerate Pyroxylic Alcohol, Iodide of Arsenic, 
Compounds of Antimony and Barium, Mylabris (a sub- 
stitute for Cantharis), Chloroform, Cullodion, Butea Seeds 
and Kosso (Vermifuges) Magnesium and its compounds. Cod 
Liver Oil, Castor Oil, &c. 
The new fomulae comprise, Potassio-tartrate of Antimony, 
Iodide of Potassium, Chloride of Zinc, & c. 
As specimen articles for quotation, we take “ Barium ” 
“ Chloroform,” and “ Butea Seeds 
“ Barium. 
“ This metal was obtained by Sir H. Davy by subjecting its 
hydrated oxide to electrolytic action in combination with 
mercury, when an amalgam was formed at the negative 
electrode. The mercury being distilled off, barium remained. 
It may also be produced by passing the vapour of potassium 
over baryta heated to redness in an iron tube. The reduced 
barium is to be removed by means of mercury, and this after- 
wards distilled off. 
“ Barium is a metal of a steel gray colour, specific gravity 
above 2. Symbol Ba. Atom. 6‘9. It rapidly absorbs oxygen, 
and when gently heated burns with a red light. Projected 
into water it decomposes it, evolving hydrogen, and forming 
a solution of baryta.
