persons really desirous of inspecting the collections, take the trouble to procure 

 a ticket, with which they feel responsible for their conduct; the introduction of 

 crowds is also avoiiled, which, from constant motion, give rise to dust, so detri- 

 mental to the more perishable articles in a natural history collection. The janitor, 

 who keep^ a register of the names and residences of visitors to the Museum on the 

 Exhibiiion days, informs me that upwards of three thousand persons have availed 

 themselves of this privilege since the middle of May las*, when the new 

 arrangement went into effect. This is an average of about 380 admissions per 

 month, or nearly 5000 per annum.
