242. On the poisonous effects of the Seeds of Hemlock. In Lindley's ' Introduction 

 to the Natural System,' 2nd ed. p. 22, it is stated tbat " the fruit of the Unibellifera' 

 is in no case dangerous." In the 'Pharmaceutical Journal' of this month, p. 337, Dr. 

 Pereira mentions the case of a gentleman who suffered severely from having drank an 

 infusion of anise, in which some seeds of Conium maculatura were detected. From 

 the expressions used by the Dr. I presume that they were not numerous. It appears 

 to me veiy desirable that the point should be set at rest. Dr. Maton is quoted by Pa- 

 ris in his Pharmacologia, as stating that the value of Extractum Conii is much in- 

 creased by including the seeds in the preparation. If any confidence is to be placed 

 in the case detailed by Dr. Pereira, which is taken by him from the ' Journal de Chi- 

 mie Medicale' for August, 1842, it would appear that an infusion of the seeds is infi- 

 nitely more powerful than tlie extract usually procured in commerce, since Dr. John 

 Davy has admistered the latter in drachm doses daily, with scarcely any untoward 

 symptoms. — Geo. Sparkes ; Bromley, Kent, November 5, 1842. 



243. On the folia accessoria of Hypnum filiciriiim, Lin. A short time ago, whilst 

 walking along the banks of one of our rivers, I haj'pened to take up a tuft of that state 

 of Hypnum filicinum which has been called H. fallax by Bridel, and on scrutinizing 

 it with my pocket-lens, was surprised to observe, scattered here and there on the stem, 

 several minute leaflets, scarcely one tenth so large as the true leaves, but yet resem- 

 bling them in appearance. I brought the tuft home with me, and took an early op- 

 portunity of examining it with the microscope. I found these " folia accessoria '' to 

 occur chiefly towards the summit of the main stem, and more sparingly on the princi- 

 pal branches. In shape they are lanceolate, denticulate at the margins (a), nerveless 

 (so far as I have observed), more delicate and with a wider reticulation than the true 

 leaves. Sometimes they stand singly, as in figures b, c, d ; not unfrequently several 

 are found near each other, when they are smaller than usual ; but most generally they 

 stand in pairs, one leaflet partially overlying the other (c/). I observe them to be si-
