mm Dorfi (Fig. 4. 28.^ not unlike the Sacroliwibalis above noted, was 

 not fo thick and fle(hy at it's Origin from the Os Ilium , hacrnm ^ and 

 Vertebra of the Loins 5 nor was it's external Surface in the Pygmre fo 

 tendinous, as in Humane Bodies^ but was fomewhat broader. The 

 ^tadratm Lumbonun was longer than in Me», agreeable to the fpace 

 between the Spine of the Os Jlium^ and lower Rib of this Animal. See 

 the Figure of the Sceleton. The Sacer^ and ScKfij^inatm , differ'd not 

 from the Humane^ as I have reprefented them in my Myotomia Reform at a^

The Miifcles of the Superior Parts and Trunk of the Body being di- 

 fpatch't,we come next to thofe of the Limbs ; and firft of the Arm or Os 

 Humeri. The Pe^oralk (Fig. 3.53.) was much broader at it's Original, 

 from the Sternum, than in Man : it's Fibres were decuflated near it's 

 Infer tion. ■ Galen and Jacobus Sylvim take notice of another Mnfch un- 

 der the Pe& oralis in Apes^ which is implanted into the Arm near the 

 Peroral Mufde. Thi Deltoides (Fig. 3. 1 5. aiid 4. 12.) was alfo broa- 

 der at it's Original. Jac. Sylvim tells us, this Mufcle in Apes is like that 

 of a Man. The Suprajpinatm (Fig. 4. 8.) agreed with the Humane in 

 it's fituation :, but was fomewhat broader at it's Origin from the upper 

 -part of the Bafis ScapuU. The Infrajpinatus, as the former Mufcle was 

 broader at it's Original from the Scapula, this on the contrary was there 

 -narrower than the Humane. Sylvius Aud Drelinconrt mention thek Muf- 

 cles in Apes j but whether they refemble thofe of Men., or this Animal, 

 do's not appear by their Accounts. Teres minor , ( Fig. 4. 10. ) this is 

 fometimes wanting in Men : it was fomewhat thorter and thicker in this 

 Animal. The Teres major, (Fig. 4. II.) was very large in the Pygmie. 

 The Latijfiwus Dorji agreed with the Humane in it's Original and Pro- 

 grefs towards the Ann ^ but when it arrived at the JxiZ^^, it parted with 

 a flelhy Portion, which defcended on the infide of the Arm, with the 

 Mnfc 111 m Biceps, and becoming a flender Tendon is inferted to the in-' 

 tcrnal protuberance of the Oj-Jy//«/cri/ f w<^e Fig. 8. C, ) which repre- 

 fentS the production of this Mufcle. Th\s Appendix ox Acceffory Mufcle 

 of die Latijjiinm Dorfi, is not peculiar to this Animal ; the like being 

 found in Apes according to Jacobus Sylvius , who, I am inclin'd to think 

 is raiftaken, in reprefenting it's Infertion at the Olecranum of th^t Ani- 

 mal :. This part of the Latijjimuf Dorfi feems a proper Inftrument in 

 turning the Os Humeri to a prone Pofition, when, thefe Animals go on 

 all four, for the more advantagious ftepping with the Fore-feet , by 

 raifing the Os Humeri^^nd turning it backwards. Galen in Lib. de Muf- 

 culk, C^/j.XIX. defcribes this Appendix of the Latijfimus Dorfi, under the 

 Title ok \ fmall Mufcle found in the Articulation of the Shoulder. The 

 Coracobrachial^ was like that in Man, but had no divifion in it for any 

 Nerve to pafs through. The Subfcapularis was alfo like that in Mati.
