to Goltzius, is tlie 7th year after the Roinans first stamped silver money ; and, 

 to mention no more, many are of the Serratos, filed in small notches round the 

 edge, of which sort I have of Scipio Asiaticus, &c. and other consular pieces, 

 but never saw any of a later date. 



v/w Account of some Indian Plants, &c. tvith their Names, Descriptions, and 

 Firtiies. Communicated in a Letter to Mr. James Fetiver, yiljotliecary and 

 F.R.S.from Mr. Sam. Brown, Surgeon ai Fort St. George. N°244, p. 313. 



Forty-six plants collected by Mr. Brown at Unanercoonda, were sent, with 

 their Malabar names, to Mr. Petiver for his examination. Mr. P. gives the sy- 

 nonyms of these plants from the Hort. Malabar, from Pluckenet's Phytogr. 

 Ray's Hist. Plant. &c. with their descriptions and uses. 



Concerning Magnetical Sand. In a Letter from Mr. Butterjield to Dr. Lister, 



N°244, p. 336. 



I send you a little of that black sand which in Italy they use instead of dust 

 to their letters; it is found 6 miles from Genes, near St. Piere d'Araine, on the 

 sea-shore. It has the properties of the load-stone, and I believe that it is 

 loadstone, or the powder of it, for it follows the loadstone ; it also sticks to a 

 knife that is touched with the loadstone : it draws a magnetic needle ; does not 

 ferment with aquafortis, like iron dust; does not rust with any acid that can be 

 put to it ; nor sparkle in the flame of a candle, like steel dust. It is commonly 

 found on the sea-shore after great storms.

An Objection to the new Hypothesis of the Generation of Animals from Anima!- 

 cula in Semine Masculino. By Dr. Martin Lister, Fel. Coll. Phijs. and R. S. 

 N° 244, p. 337. 



Amongst the many arguments which I have used to confute the opinion of 

 Mr. Leuwenhoeck about the generation of animals from innumerable little ani- 

 mals in semine masculino, one I omitted, which is as follows :* 



Rursus quajro, si humanuiTi corjuis nascatur ab animalculo e semine mascu- 

 lino unde sint ista animalcula genita? et quidem generantur ad plurimos annos; 

 scilicet ab adulto viro ad extremam usque senectutem ; certeacoitu peracto longe 

 maxima eorum pars ejicitur; unde nova soboles indies succrescat, necesse est. 

 An vero hoec animalculorum proles fere diurna a sui similibus animalculis gene- 



* From the peculiar nature of this subject it has been deemed proper to reprint this short but cogent 

 objection against the hypothesis of Leuwenhoeck in the original Latin.
