the vena cava. The artery carrying the blood from this heart was inserted into 

 the artery lately described, as well as that of the other heart. So that if the 

 blood circulated through either of them, the whole animal must necessarily be 

 supplied with blood; a contrivance not unlike that of the arteries under the 

 brain, where the arteriae carotides and vertebrales empty themselves into one 

 common channel, from which all parts of the brain may easily be supplied with 

 blood. The head was joined to 2 necks about the processus mammillares. There 

 were 4 orders of ribs, though the body was but one above the navel. That 

 which outwardly seemed to be a back, was really the place where the ribs met, 

 and which might be rather called the breast, though it wanted a sternum.

In treating of any disease, this author notices, 1 . The history of the distemper. 



2. The part affected. 3. The causes. 4. The prognostics. 5. The method 

 of cure. — He looks upon it to be of the greatest consequence to distinguish 

 between the animal faculty, placed in the spirits and genus nervosum, and the 

 vital, whose seat is in the blood and viscera. He commends Sylvius, Willis, 

 Sennertus and Helmont. The work is divided into 3 parts, to the last of which 

 are subjoined his Chirurgia Medica and Collegium Consultatorium; besides an 

 Appendix, consisting of several tracts. 



* This physician, who acquired great reputation as a teacher and an author, and who travelled in 

 the pursuit of knowledgs through the most enlightened parts of Europe, was born at Leipsic 1644, 

 (not 1646.) He died when only 39 years of age, of a hectic fever, brought on by his unremitting 

 exertions for the advancement of his profession. Ettmuller was much devoted to the chemical 

 theories of his days, and his pathology, founded thereon, now ceases to be received. He bestowed 

 much attention on pharmaceutical chemistry, and wrote commentaries on Schroeder and Ludovicus; 

 but, although in some instances he animadverted upon certain compositions in the dispensatories of 

 those authors, remarkable for the number and contrariety of ingredients; yet he concurred with 

 them in praising many substances described in their materia medica, which every man of reflection 

 must condemn as useless, disgusting, superstitious, absurd: such, for instance, as the calculus hu- 

 manus, as a diuretic and sudorific; the blood of a hunted hare, as a remedy against epilepsy ; broth 

 made from the spleen of an ox, against suppression of the menses ; and the internal use of the 

 dung of various animals, in cases of jaundice, vertigo, colic, &c. We cannot therefore allow to 

 Ettmuller the merit of having rendered the materia medica less redundant or more rational than he 

 found it; nor of having contributed much to that which until within these few years was so greatly 

 desired, the simplification of officinal and extemporaneous formulae. — More complete editions of his 

 works than that above noticed were afterwards published, one by the author's son in 3 vols, folio, 

 17O8; and another by Cyrillus, professor of physic, at Naples, in 4 vols, folio, 1728 and 1736.
