United states pharmacopeia was establish in 1820
<h2>They discovered animals and other things. Maybe this could help</h2>
Is there any choices for this ??
The modern development of today's world would have first made the routes safer. Today we have the safety of common things such as police officers, hospitals, e.t.c. Transportation of goods would have been easier, and it would have been easier to carry larger amounts of goods at one time.
hope this helps :)
