analogous to alkanct red. By subsequent trca-tment with alcoliol an 

 alkaloid was obtained which the authors term cytwglossine. It is 

 liygToscopiCj- combines with acids, formdug uncrystallizable salts 

 which are decomposed at 100^ 0. The base was also found in the 

 seeds, but not in the leaves or stalk's. Cynoglossine has a toxic 

 action; injected hypoderniically O'OOl to 0*002 gram caused violent 

 convulsive movements in a frog, followed by death after several 

 hours. O'ffSO gram repeated several times caused nausea and vomit- 

 ing in a pigeon and death without convulsions. In a rabbit weighing 

 3'5<)0 kgs, a dose of about one gram produced narcotism and convulsive 



movements. {Fharm. F'ost^ xxv.j 1.)

The tomato f rait ha? b3eu chemically examriaed by G. B-riosi and 

 T. Gigli. Oa an average the fresh fruit contains: Seeds 10*9 per 

 cent,, pulp 85*4 per cent., and skin 3r-7 per cent. The pulp can be 

 separated into a yellow juica aad a red residue, which is tasteless 

 after washing ; the juice on an average has the specific gravity 

 1'021T, and contains leviilose, citric acid (0'4 to 0'65 per cent, of 

 the Juice), albuminoids, and ash which is composed of 60 per cent, 

 potassium salts. Minute traces of alkaloid are indicated ; tartaric 

 acid could not be detected. The red residue will impart its colouring 

 matter to ether, alcohol, chloroform, and aqueous alkalies. The 

 alcoholic solution is not changed by ferric chloride, dilute acids or 

 Ikalies ; on addition of strong nitric acid a transient blue colour is 

 produced; the residue on evaporating the alcoholic solution becomes 

 blue by adding sulphuric acid ; the colouring matter resembles that 

 of saffron. iChemlher Ztg,, 1891, 205,) 



Mr. Frederick Davis has found that English-grown tomatoes sub- 

 jected to distillation with water afford a volatile substance analogous 

 to oil of onions or garlic. The crude oil obtained by distilling 

 twenty-eight pounds consisted of oxide and sulphide of allyl. The
