Illustrating Dr. G. Things paper on the Formation of 

 Blood-vessels, as observed iu the Omentum of Young 

 Rabbits. 



Fig. 1. — A milky patch, iuto the larger interstices of which injection 

 mass has penetrated from a capillary, (a) capillary ; (b) interfasicular space 

 in communication with the vessel ; (c) stellate space in the membrane ; 

 (fi?) border of the patch, which is defined by a faint staining by picro- 

 carminate ; (e) nucleus of flat cell. 



Fig. 2. — Osmic acid and subsequent staining by logwood. («) and (b) 

 branched cells ; (c) nuclei of flat cells. 



Fig. 3. — Purpurine staining, (a) space ; {b) lymph corpuscle ; (c) 

 nucleus of spindle cell in the wall of the space. 



Fig. 4. — Osmic acid and subsequent staining by logwood, (a) spindle 

 cell in wall of space ; a small vacuole in the cell corresponds to the point of 

 escape of a rounded body ; (b) the space j (c) lymph corpuscle. 



Fig. 5. — Picrocarminate. (a) capillary formed ; (b) enlarged spindle 

 cells indicating tract in which a capillary would develop ; (c) lymph- 

 corpuscle.
