'JO PHILOSOPHICAL TRANSACTIONS. [aNNO I673. 



distributed over the surface of their kings in a wonderful manner, so as to resem- 

 ble a beautiful net-work ; and its minute branches strike into the interior vesi- 

 cles, where the eye may trace the anastomosings with the pulmonary vein. This 

 vein is twice as large as the artery. It is situated in the cavity of the lungs, (in 

 pulmonum cavo), and especially in the margins or borders of the vesicles, from 

 whence its capillary and almost; invisible ramuli are distributed to all the cells, 

 and even to the investing membrane itself. 



The animals which I suspect to possess the same pulmonary structure with 

 frogs, are toads, lizards, serpents, the chamaelion, tortoises, the salamandra 

 aquatica, &c. but these I have not yet had opportunities of dissecting and exa- 

 mining. I must therefore be contented with having pointed them out to other 

 abler inquirers. 



As I perceive you were pleased with my observations on the organs of genera- 

 tion in the scarabasus nasicornis, I have thought it right to transmit to the Society 

 a drawing thereof; wherein are represented the testicles composed of a single 

 tube, 2 feet 6 inches long; the vasa deferentia, out of which drops a quantity 

 of white seminal liquor, whenever they are cut or punctured ; six vesiculae or 

 rather glandulae seminales, extremely elegant ; and the ducts which proceed from 

 the glandulae seminales, containing a yellowish seminal liquor, as in men and 

 brutes.

I. La Statique, ou La Science des Forces Mouvantes, par le P. Ignace Gaston 

 Pardies. A Par. 1673, in l-Zmo. 



The learned Author of this book had proposed to himself to write a whole 

 body of mechanics, such a one as might be adapted to ordinary capacities; con- 

 ceiving that there had not been extant hitherto a complete system of that science ; 

 or if there had, it was beyond the reach of most readers: w^hich latter he thinks 

 to be the character due to Dr. Wallis's 3 vols, de Motu et Mechanice. But 

 since the publication of this part of it, vve understand that he has been prevented 

 and cut off by an untimely death ; being regretted by those that knew his frank- 

 ness and strong inclination to promote philosophical knowledge. 



IL Antoniile Grand Hi storia Naturae. Lond. 1673, inSvo. 



The learned author of this book, desirous to show that even the common and 

 obvious phaenomena of nature can be very well explained and accounted for 

 by those principles he had formerly laid down, and published An. 1672, under 

 the title of Institutio Philosophias, described in Numb. 80 of these tracts ; he 

 undertakes in this treatise, to pass through the whole body of physiology, and 

 in so doing, to supply in due places what he has omitted in the said institution.
