THEATRE OF ANATOMY, 

 Blenheim-Street, Great Marlborough-Strcet. 



THE AUTUMNAL COURSE of LECTURES on ANATOMY, 

 PHYSIOLOGY, and SURGERY, will be commenced on Thursday, 

 the 1st of October, at Two o'Clock, 



By Mr, BROOKES. 



IN these Lectures the Structure of the Human Body will be demonstrated on recent 

 subjects, and further illustrated by preparations, and the functions of the different 

 organs will be explained. 



The Surgical operations are performed, and every part of Surgery so elucidated a» 

 may best tend to complete the operating Surgeon. The art of Injecting, and of makr 

 ing Anatomical Preparations, will be taught practically. 



Gentlemen zealous in the pursuit of Zoology, will meet with uncommon opportu- 

 nities of prosecuting their researches in Comparative Anatomy. 



Surgeons in the Army and Navy may be assisted in renewing their Anatomical 

 Knowledge, and every possible attention will be paid to their accommodation as well 

 as instruction. 



Aiiatomical Convcrzatioues will be held weekly, when the different Subjects treated 



of will be discussed familiarly, and the Students' views forwarded. To these none 



but Pupils can be admitted. 



Spacious Apartments, thoroughly ventilated, and replete with every convenience, 

 are open all the Morning for the purposes of Dissecting and hijecting, where Mr. 

 Brookes attends to direct the .Students, and demonstrate the various parts as thoy ap- 

 pear on Dissection.

The Inconveniences usually attending Anatomical Investigations are counteracted 

 by an antiseptic Process, the result of Experiments made by Mr. Brookes on Human 

 Subjects, at Paris, in the year 1732, the account of which was delivered to the Roval 

 Society, and read on the 17th of June, 1784. This method lias since been so far im- 

 proved, that the florid colour of the Muscles is preserved, and even heightened. Pu- 

 pils may beaccommudattd in the House. Gentlemen established in Practice, desirous 

 of renewing their Anatomical Knowledge, maybe accommodated with an Apartment 

 to Dusect in privately.
