The undertaking of tlie anthorS; in the preface of the first volume, 

 to supplement the previous work published by Dr. Dymock with 

 original investigation concerning the chemical c oiiiposition and 

 physiological action of Indian drugs, and to give toxicological 

 statistics relating to the more important drugs^ has been most 

 conscientiously carried out. Consequently the present part, which 

 completes the second volume, does not extend fuilher than Nicotiana 

 Tabacum, and the two volumes ah'eady published contain, as nearly 

 as possible, twice as much matter as can be foimd in the ' Materia 

 Medica of Western India,' up to the same point. Yet there still 

 remains enough matter to be treated of to fill at least one more 

 volume. Several new alkaloids have been discovered dm'ing the 

 chemical examination to which some of the hitherto unexamined 

 articles of materia medica have been subjected. Of these some have 

 received a name, but of others only sufficient has been obtained to 

 indicate their presence. Of those which have received a name may 

 be mentioned — Bahmanine from red behen root ; Nyctanthine from 

 Nyctanthes arbor trhtis ; Jasminine ixom. Jasmmuni yrandijlomm ; 

 Salvadoiine from Salvadora persica ; Tylophorine from Tylophora 

 asthmatica : Dsemine from Dtcmta extensa; and Cuscutine from a 

 species of Cuscuta. A new glucoside, to which the name of Dregein 

 has been given, has been discovered in Dregea volubilis^ an asclepia- 

 ,i..^.„_ plant, and another, viz., gymnemic acid, in Gymnema
