194 PREPARATION AND MOUNTING 



I used the common syringe, and filled the leg with the 

 liquid. We then placed it in cold water, and allowed it to 

 remain UDtil the next morning. 



The first work was to remove a piece of the skin, and 

 take sections of it by the aid of a Valentin's knife. Tho 

 arteries were shown beautifully; but the most attractive 

 part was where the growth of the hair was laid open before 

 us. Each hair exactly resembled a common onion, whilst 

 every bulb was surrounded by a perfect network of arteries ; 

 and where any bulb had been torn out by accident, there 

 was left a minute bird's-nest of them, clearly showing how 

 they had been intertwined around some lost friend. Dif- 

 ferent sections of the muscular portions showed every phase 

 of arterial distribution, with some exquisitely minute vessels 

 in parts. I then took an artery and cut cross sections, in 

 which the carmine portions were as closely interwoven as 

 wickerwork. I also, with a pair of scissors, laid open a 

 length of the artery, and mounted it, together with a cross 

 section. In the same way I used the veins. Many of the 

 nerves we took out, and, after cleaning carefully with knives 

 and small brushes where necessary, mounted them with 

 the attendant arteries around them. But as we approached 

 the hoof, double interest was given us. The skin with its hairs 

 just above the hoof plainly showed the change taking place, 

 and sections of the hoof gave beautiful specimens of where 

 circulation was gradually stayed by the growth of harder 

 substance. Here, too, we reached the laminae, or thin 

 plates (somewhat resembling the gills of certain fishes), 

 the exact use of which, we have no space to discuss and 

 these were readily removed by the aid of scissors and 

 knife. In these the vessels are minutely and exquisitely 

 shown. 



These are a fe* of the beauties which this injection 

 afforded me. My friend Mr. Hepworth and I worked to- 

 gether at this subject for a week or two, and part of the 

 knowledge which he gained from it was communicated to
