CAMBRIDGE, Mass. (AP) _ New graduates of Havard's business administration school waved dollar bills. Law school grads popped open champagne. But at the Public Health School, graduating seniors on Thursday tossed condoms inscribed in Latin.

The 210 people receiving Public Health masters degrees shouted ''condoms'' and tossed the mementos to classmates in celebration of graduation and as endorsement of use of prophylactics in the fight against AIDS.

The condoms, wrapped in white envelopes, were inscribed ''Harvard School of Public Health Class of 1987'' and below that ''Ad Venerem Securiorem,'' Latin for safe sex.

The rest of the crowd cheered.

Parveen Morani, 34, a graduate from Pakistan, ''This time we came up with the idea that this is the time to convey the idea of safety. I think its a good idea to do it here because the majority of the public is going to believe it.''

Graduate Tom Baiocchi, 37, of Gray, Maine, said the class decided to toss the condoms because, ''It's clearly a good idea to protect yourself from AIDS and venereal disease. Also, the idea of throwing condoms is good clean fun.''

Other schools showed their interests as well. The medical school contingent yelled and ripped up legal pads. Opponents of the school's investments in firms doing business in South Africa flew pink balloons imprinted: ''Divest the rest.''
