COLLEGE REL'ORD. 191 



Imtched out by the heat of the sun, and an innumerable progeny of in- 

 sects, which are nearly all females, distribute themselves over the plants. 

 These, after some time, nearly lose their power of locomotion, attach 

 themselves to the leaves, grow rapidly in size, and are brushed off by 

 means of a blunt knife, and destroyed either by the heat of a stove or 

 dipping them enclosed in a sack into boiling water, and subsequently 

 dried. 



The insect of the shops is in the form of irregularly circular or oval 

 grains, marked with transverse wrinkles. These are bruised and infused 

 in water, from which alumina throws down a beautiful red precipitate 

 called a lake^ the salts of tin or acids produce the brilliant pigment 

 called carmine^ and the salts of potash a purple dye. 



The insects observed by Parrot "were collected together in large 

 nests, round the roots of a short, hard species of grass, the Dactylis lit- 

 teralis, which grows in large quantities in the vicinity, where they may 

 be gathered in abundance." "■This," he farther remarks, "is a discov- 

 ery of some interest to the commercial speculations of Russia, and one 

 which, imder proper management, might become a source of profitable 

 occupation to those provinces. The value of these insects is well un- 

 derstood in Persia, where they are very generally used for dyeing scar- 

 let, and, in fact, throughout every part of the East ; the prepared insects 

 being sold, sometijnes at a very high price."

The Summer Session of Pennsylvania College commenced on the 

 21st ult. It gives us pleasure to be able to inform our numerous friends 

 abroad, that the session has opened with the most encouraging pros-

 attendance during last session, have, with a lew exceptions, returned. 

 The annual Catalogue, which will be issued in August next, will show 

 a large increase above the last, and a larger number than has ever, here- 

 tofore, been in attendance, during any one year, at the Institution. 



This College is yet comparatively in its infancy, and, having been 

 permitted to gain its way into public favor almost entirely as its merits 

 developed themselves before the people, without any puffing or unfair 

 representation, on the part of its friends, it has but recently become gen- 

 erally known. That an institution, possessing so many facilities for the 

 acquisition of knowledge, and holding out so many inducements for 

 young men to enter its walls, should be patronized by an intelligent pub-
