Account of a Booh, viz. — Myotomia Reformata : or, A New Administration of 

 all the Muscles of Human Bodies; ivherein the true Uses of the Muscles are 

 explained, the Errors of former Anatomists concerning them confuted, and 

 several Muscles not hitherto taken notice of described : to which are subjoined, 

 a Geographical Description of the Bones, and other Anatomical Observations. 

 Illustrated with Figures after the Life. By JVilliam Cowper, Surgeon. 

 Lon. 1694, 6vo. N°213, p. 1'lQ. 



This excellent work on the muscles is so well known to all anatomists, that 

 it would be superfluous to insert an account of its contents. Cowper's anato- 

 mical merits have been already noticed in the account of his life, at p. 6l5, of 

 this volume of the Abridgment,

The abbot Galloys having, in the year 1693, asserted that Mr. James Gregory 

 and Dr. Barrow had stolen their general propositions concerning the transforma- 

 tion of curves from M. Robervall ; Dr. David Gregory here fully refutes that 

 assertion. For Mr. Gregory published his book at Padua 1668, and Dr. Barrow 

 his Lectiones Geometricae 1674, which M. Robervall doubtless had a sight of 

 before he died, which was not till October 1675, yet he never complained of 

 any such injury done him.

 Jupiter, reduced to the Julian Stile, and Meridian of London. N° 214,

Among the books with which the Royal Academy of Sciences at Paris has 

 lately gratified the world, there is one entitled, Recueil d'Observations faites 

 en plusieurs Voyages pour perfectionner I'Astronomie et la Geographic, avec 

 divers Traites Astronomiques. In which those sqavans have set a very com- 

 mendable example in ascertaining by undoubted observations the true geogra- 

 phical site of all the principal ports of France. The method they have used to 

 determine the longitudes of their places, is by the observation of the eclipses of 

 the first satellite of Jupiter, which they find almost instantaneous, and with 

 good telescopes discernible almost to the very opposition of Jupiter to the sun : 

 and it may be said, that this account of the longitudes observed has put it past
